When doing a two-trait cross, the genotypes of the parents require how many letters? A) one B) two C) three D) four

Answers

Answer:

D) four

Explanation:

When doing a dihybrid cross, it's assumed that there is two alleles for each gene. Two traits requires two genes, and two genes requires four alleles, or "letters"

The genotypes of the parents require ( D ) : Four

A  two-trait cross ( dihybrid ) is a cross between 2 individuals who are heterozygous at 2 loci

example of a two-trait cross

dihybrid cross between Tall plants with Brown flowers

genotype for each plant ( heterozygous ) = TtBb

Therefore the cross = TtBb * TtBb

where : T ( tall ) = dominant

             t ( dwarf ) = recessive

             B ( brown ) = dominant allele

             b ( white ) = recessive

Hence the parents genotypes will require 4 letters ( TtBb * TtBb )

Man-made ozone at Earth's surface, bluish in color, and can cause breathing difficulty is
what form of ozone?

Answers

Answer:

Bad form.

Explanation:

Bad form of ozone causes breathing difficulty due to its availability near the surface of earth and its composition. Ozone is not emitted directly into the air, it is created due to the chemical reactions between oxides of nitrogen and volatile organic compounds. When these pollutants react with each other in the presence of sunlight, ozone is produced which leads to difficulty of breathing as well as damages the vegetation so this ozone is considered as bad ozone.

presence of the placenta (mammals)

Explanation:

Cat and dogs are two species that belong to the group of placental mammals (class Mammalia). Some phenotypic traits that are exclusive of mammal species include, among others, mammary glands, presence of hair or fur, sweat glands, specialized teeth, etc. A phylogenetic tree is a representation of the evolutionary relationships among different groups/taxa. Moreover, cats and dogs represent two different species of placental mammals, which are characterized by the presence of the placenta (an organ that facilitates the exchange of nutrients during gestation). In this case, the remaining two branches in the phylogenetic tree (branches from left to right) separate from more closely related to less closely related taxa that diverged from the same ancestral node.

0 Effects of oil discharged into the ocean​

Answers

Explanation:

Oil spills at sea are generally much more damaging than those on land, since they can spread for hundreds of nautical miles in a thin oil slick which can cover beaches with a thin coating of oil. These can kill seabirds, mammals, shellfish and other organisms they coat.

Depending on the circumstances, oil spills can be very harmful to marine birds, sea turtles and mammals, and also can harm fish and shellfish. Oil destroys the insulating ability of fur-bearing mammals, such as sea otters, and the water-repelling abilities of a bird's feathers, exposing them to the harsh elements.

Owls and foxes compete fiercely against each other for small rodents in their habitat.
Brightly colored cardinals are better able to survive and to reproduce than darker cardinals.

Answers

Answer:

Brightly colored cardinals are better able to survive and to reproduce than darker cardinals.

Explanation:

Variation definition- any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation). Variation may be shown in physical appearance, metabolism, fertility, mode of reproduction, behavior, learning and mental ability, and other obvious or measurable characters.

The brightly colored cardinals are able to survive and reproduce because of variation in a species. Your question states "Variations within a species", so with that clue we can eliminate A and C (examples of competition) And B does not mention variation in a species. So we can conclude that D is the correct answer, since the brighter cardinals are able to survive and reproduce better than the darker cardinals, this is an example of Variation.

 

Due to variation, brightly colored cardinals are better able to survive and reproduce than darker cardinals. The correct answer is d) Brightly colored cardinals are better able to survive and reproduce than darker cardinals.

What is the variation?

Any difference between cells, individuals, or populations of organisms of any species that result from genetic variations or from the influence of environmental circumstances on the manifestation of the genetic potentials (phenotypic variation) is referred to as variety. Physical characteristics, metabolism, fertility, mode of reproduction, behavior, learning, and mental capacity, and other evident or measurably different characteristics can all vary.

Natural populations exhibit variation, and every population has more offspring than the environment can support. The result of this overproduction is that those people who have the highest level of environmental genetic fitness will have kids who are better able to compete in that environment.

Variation within a species allows for the survival and reproduction of the vividly colored cardinals.

Therefore, the correct answer is d).

Explanation:

A "TT" (tall) plant is crossed with at "tt" (short) plant. What percentage of the offspring will be tall?

Answers

Answer:

100%

Explanation:

My biology teacher taught me the FOIL method. F=first, O=outside, I=inside, and L=last.

TT x tt

The first letter of each parent together would be Tt, T=tall so the plant would be tall, 25%

The outside letter of each parent together would be Tt, T= tall so the plant would be tall, 25%

The inside letters of each parent together would also be Tt, T=tall so the plant would be tall, 25%

The last letter of each parent together would also be Tt, T=tall so the plant would be tall, 25%

Each outcome has a T, and that is dominant so therefore, the plants will always be tall. You could also think about it as a letter has to be passed down to each child and the first plant only has capitals to pass and the second only has lowercase to pass down.

100% of the offspring will be tall.

What are Gametes cells?

Answers

Answer:

I think Gametes are mature male or female reproductive cells that fuse together resulting in a zygote during sexual fertilization. The key difference between somatic cells and gametes depends on the ploidy of the genome. Somatic cells consist of diploid (2n) genome while gametes consist of a haploid (n) genome.

Hope it help you!:)

Answer: Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. ... In contrast, each egg cell, or ovum, is relatively large and non-motile.
