Consider a breeder that mates two heterozygous black Staffordshire bull terriers over the course of three years. The dam eventually produces 16 puppies: 11 are black like the parents, 4 turn out white, and 1 turns out gray colored. As a genetics student, what do you think of this outcome

Answers

Answer:

Different colour occur due to heterozygous nature.

Explanation:

Most of the puppies just like parents because the black colour gene or allele is dominant over other colour allele whereas other colour puppies also formed due to presence of heterozygous type of alleles. Other colour occurs due to appearance of recessive allele in the physique of the offspring or formation of hybrids occurs which causes colour other than black and white in the offspring. In the F1 generation all the offspring resembles to the male parent but after this generation some offspring resembles to male, some are hybrids and other resembles to female.

So, option B is correct one.

What is binary fission?The simplest meaning of binary fission is division into two. The binary fission is the most common methods of asexual reproduction.In biological , division of single entity into two or more parts and regenerates of these parts again and each parts have potential to grow to the size of the original cell.Binary fission occurs in Amoeba which is unicellular organismThe binary fission is type of asexual reproduction.

A scientist is studying metabolic rate in a Giant Hummingbird in Peru. The scientist assumes a captured individual has been feeding on nectar (glucose) recently, but in fact the individual has not fed in the last hour and is currently metabolizing fat (palmitic acid). 3. Calculate the measurement error the scientist would introduce based on their faulty assumption if the scientist were measuring CO2 production. Will the scientist over- or underestimate metabolic rate

Answers

Answer:

Yes.

Explanation:

Yes, the scientist underestimate the metabolic rate of Giant Hummingbird. The scientist experience the measurement error due to non-feeding of Giant Hummingbird that leads to faulty assumption when the scientist were measuring CO2 production because the Giant Hummingbird breakdown the fats of the body for the release of energy instead of glucose. There is difference in the production of carbondioxide rate due to difference in the composition of fats and glucose.

Name two reasons that viruses are considered nonliving.

Answers

Answer:

The virus simply can't replicate. Viruses fail the second question for the same reason. ... Finally, a virus isn't considered living because it doesn't need to consume energy to survive, nor is it able to regulate its own temperature. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.

Explanation:

Viruses, like bacteria, are microscopic and cause human diseases. ... Viruses also lack the properties of living things: They have no energy metabolism, they do not grow, they produce no waste products, and they do not respond to stimuli. They also don't reproduce independently but must replicate by invading living cells.

You are studying a new gene "X" that you think controls skin color in Bearded Dragons. In order to determine what gene X does you need lots of gene X DNA to work with. So, you decide to amplify it through the process known as PCR. You have a forward and a reverse primer that have been designed to gene Xf – a gene in frogs that is similar to the one found in the Bearded Dragon. You are pretty sure that these two primers will work in Bearded Dragons, so you decide to go ahead with the PCR. In frogs, the Forward Xf primer binds gene Xf between nucleotides 32 and 47. The Reverse Xf primer binds between nucleotides 1110 and 1135. What size PCR product would these two primers create if they amplified the frog gene Xfp

Answers

Answer:

The correct answer is - 1103 bp.

Explanation:

PCR or polymerase chain reaction is a process that uses a primer to amplifying the desired segments of DNA molecules. It is a technique that can amplify a million copies of the DNA segment.

given:

forward primer binds from - 32 to 47

reverse primer binds from - 1135 to 1110

PCR product would be between - 32 to 1135

So, product size would = 1135-32 = 1103.

Thus, the correct answer is - 1103.

The light-independent reactions of photosynthesis, also known as the Calvin cycle, must repeat three times in order for a cell to have enough material to construct half a glucose molecule. A variety of molecules are used and produced during this process. Identify the molecules into three categories: molecules brought in and used in three turns of the Calvin cycle, molecules produced during three turns of the Calvin cycle that leave the cycle, and molecules used and regenerated within the Calvin cycle during three turns.

Answers

Answer:

- molecules brought in and used in three turns of the Calvin cycle = carbon dioxide (CO2)

- molecules produced during three turns of the Calvin cycle that leave the cycle = Glyceraldehyde-3-phosphate (G3P)

- molecules used and regenerated within the Calvin cycle during three turns = Ribulose bi phosphate (RUBP)

Explanation:

The second stage of photosynthesis, called CALVIN CYCLE, occurs in the stroma of the chloroplast. The processes that occur in this stage can be divided into three stages namely: carbon fixation, reduction and regeneration.

As rightly stated in this question, the calvin cycle must repeat three times in order for a cell to have enough material to construct half a glucose molecule. Hence;

- In carbon fixation, molecules of carbon dioxide (CO2) are brought in and used in three turns of the Calvin cycle. The CO2 combines with a CO2 acceptor called RUBP (ribulosebiphosphate) to produce PGA (3-phosphoglycerate).

- In the reduction stage, PGA is reduced to Glyceraldehyde-3-phosphate (G3P). This G3P molecule is produced during three turns of the Calvin cycle and leaves the cycle to be used to form glucose.

- In the regeneration stage, remaining molecules of G3P are used to regenerate RUBP in order for the cycle to continue. Hence, RUBP molecules are used and regenerated within the Calvin cycle during three turns.
