When the nursery at the hospital caught on fire, everybody rushed out with a baby. Unfortunately, after the fire was put out, the babies were in the wrong cribs. Fortunately, the hospital could type all the babies blood types.
Baby#1 was type O
Baby#2 was type B
Baby#3 was type AB.
1. Mr and Mrs jones both had type A blood. Which baby was theirs?
2. Mr and Mrs Williams had types AB and O blood. Which baby was theirs?
3. Mr and Mrs Wilson had types B and A blood. Which baby was theirs?
Answer:
baby #1 goes to family 2
baby #3 goes to family 1
and baby #2 goes to family 3
Explanation:
its simpler then it looks☺
Baby with blood group O belongs to Mr. and Mrs. Jones, baby with blood group B belongs to Mr. and Mrs. Williams, and baby with blood group AB belongs to Mr. and Mrs. Wilson.
What is a blood group?
Blood group or blood type is the classification of the blood cells into different classes on the basis of presence or absence of antibodies and antigens on the membrane of the blood cells.
The alleles which can be formed in case of Mr. and Mrs. Jones are AA or Ai type. These alleles can only result into formation of an offspring with blood group O or A. Similarly, the possible combination of alleles in case of Mr. and Mrs. Williams is AB and ii, these combinations will result into development of offspring with blood group A or B. In case of Mr. and Mrs. Wilson, the possible combinations of alleles are Ai or AA and Bi or BB, which results into formation of offspring with blood group AB.
This can also be represented through punnett square.

fossils are taken as the strongest evidence so far regarding the evolution of organisms. justify this statement
Answer:
No present empirical evidence supports the idea of that natural causes can result in an increase of complexity. The idea that descent with modification has happened in the past is supported by the fossil record. This makes the fossil record the strongest evidence for Darwin's theory of evolution
Explanation:
Fossils are defined as the preserved remains or traces of animals, plants, and other organisms from the past that are important evidence for evolution because they show that life on Earth was different from what was once found on Earth.
What are Fossils?A fossil is defined as the preserved remains, impression, or trace of a once-living thing from a past geological age, including bones, shells, exoskeletons, fossilized traces of animals or microbes, amber, hair, petrified wood, and DNA.
The totality of fossils is known as the fossil record. These are the preserved remains of plants and animals whose bodies were buried in sediments such as sand and mud at the bottom of ancient seas, lakes and rivers, including any preserved traces of life which are usually over 10 000 years old.
The different types of fossils include:
1. Petrified fossils
2. Mold and cast fossils
3. Carbon film fossils
4. Trace fossils
5. Reserved remains, etc.
Thus, Fossils are defined as the preserved remains or traces of animals, plants, and other organisms from the past that are important evidence for evolution because they show that life on Earth was different from what was once found on Earth.

In the year 2500, five male space colonists and five female space colonists (all unrelated to each other) settle on an uninhabited Earthlike planet in the Andromeda galaxy. The colonists and their offspring randomly mate for generations. All ten of the original colonists had free earlobes, and two were heterozygous for that trait. The allele for free earlobes is dominant to the allele for attached earlobes. If one assumes that Hardy-Weinberg equilibrium applies to the population of colonists on this planet, about how many people will have attached earlobes when the planet's population reaches 10,000
Answer:
100 individuals will have attached earlobes out of a population of 10000
Explanation:
From the Hardy-Weinberg equilibrium; p² + 2pq + q². Also, p + q = 1
p² = population of individuals breeding true for free earlobes
2pq = population of individuals heterozygous for free earlobes
q² = population of individuals breeding true for attached earlobes
p = frequency of dominant allele
q = frequency of recessive allele
The dominant trait is free earlobes while the recessive trait is attached earlobes.
Eight out of ten are breed-true for free earlobes, whereas, two were heterozygous for that trait.
p² = 8/10 = 0.8
p = 0.89 or approximately 0.9
q = 1 - p
q = 1 - 0.9
q = 0.1
q² = (0.1)²
q² = 0.01
For a population of 10000 persons, number of people with attached earlobes will be:
0.01 * 10000 = 100 persons
Therefore, 100 individuals will have attached earlobes out of a population of 10000

Explain how errors in DNA replication and environmental factors cause genétic variation
DNA replication is a truly amazing biological phenomenon. Consider the countless number of times that your cells divide to make you who you are—not just during development, but even now, as a fully mature adult. Then consider that every time a human cell divides and its DNA replicates, it has to copy and transmit the same sequence of 3 billion nucleotides to its daughter cells. Finally, consider the fact that in life (literally), nothing is perfect. While most DNA replicates with fairly high fidelity, mistakes do happen, with polymerase enzymes sometimes inserting the wrong nucleotide or too many or too few nucleotides into a sequence. Fortunately, most of these mistakes are fixed through various DNA repair processes. Repair enzymes recognize structural imperfections between improperly paired nucleotides, cutting out the wrong ones and putting the right ones in their place. But some replication errors make it past these mechanisms, thus becoming permanent mutations. These altered nucleotide sequences can then be passed down from one cellular generation to the next, and if they occur in cells that give rise to gametes, they can even be transmitted to subsequent organismal generations. Moreover, when the genes for the DNA repair enzymes themselves become mutated, mistakes begin accumulating at a much higher rate. In eukaryotes, such mutations can lead to cancer.

Wild boars, hogs and pigs all have just small differences externally. Their anatomy and physiology are identical. They are all mammals. They are highly intelligent and talented ones.

Answer:
biological definition of species, which works for sexually reproducing organisms, is a group of actual or potential interbreeding individuals. There are exceptions to this rule. Many species are similar enough that hybrid offspring are possible and may often occur in nature, but for the majority of species this rule generally holds. The presence in nature of hybrids between similar species suggests that they may have descended from a single interbreeding species, and the speciation process may not yet be completed.
Given the extraordinary diversity of life on the planet there must be mechanisms for speciation: the formation of two species from one original species. Darwin envisioned this process as a branching event and diagrammed the process in the only illustration found in On the Origin of Species (Figure 1a). Compare this illustration to the diagram of elephant evolution (Figure 1b), which shows that as one species changes over time, it branches to form more than one new species, repeatedly, as long as the population survives or until the organism becomes extinct.
Explanation:
For speciation to occur, two new populations must be formed from one original population and they must evolve in such a way that it becomes impossible for individuals from the two new populations to interbreed. Biologists have proposed mechanisms by which this could occur that fall into two broad categories. Allopatric speciation (allo– = “other”; –patric = “homeland”) involves geographic separation of populations from a parent species and subsequent evolution. Sympatric speciation (sym– = “same”; –patric = “homeland”) involves speciation occurring within a parent species remaining in one location.
Biologists think of speciation events as the splitting of one ancestral species into two descendant species. There is no reason why more than two species might not form at one time except that it is less likely and we can conceptualize multiple events as single splits occurring close in time.
Allopatric Speciation
A geographically continuous population has a gene pool that is relatively homogeneous. Gene flow, the movement of alleles across a species’ range, is relatively free because individuals can move and then mate with individuals in their new location. Thus, an allele’s frequency at one end of a distribution will be similar to the allele’s frequency at the other end. When populations become geographically discontinuous, it prevents alleles’ free-flow. When that separation lasts for a period of time, the two populations are able to evolve along different trajectories. Thus, their allele frequencies at numerous genetic loci gradually become increasingly different as new alleles independently arise by mutation in each population. Typically, environmental conditions, such as climate, resources, predators, and competitors for the two populations will differ causing natural selection to favor divergent adaptations in each group.
