a male guinea pig is homozygous dominant for hair texture and hair length. A female guinea pig is heterozygous for hair texture
nekit [7.7K]

If we talk about guinea pigs, the trait of hair length is controlled by a gene with two alleles.

Allele for short hair (S) is dominant on the allele for the long hair (s).

The texture of hair texture  is controlled by a gene with two alleles. It can be rough or smooth, and the allele for rough hair (R) is dominant on allele for smooth hair (r).

Now coming towards the question:

  • A female guinea pig is heterozygous for hair texture and homozygous recessive for hair length.

Phenotype of the female will be Rough and long hair.

  • A male guinea pig is homozygous dominant for hair texture and hair length.

Phenotype of the male will be Rough and short hair.

Hope it help!

In part A, you analyzed genes that contribute to two diseases. How can scientists use this information to develop new treatments
Sergeeva-Olga [200]

Answer:

Yes scientist will need to develop multiple treatments to control symptoms.

Explanation:

because if they only do one treatment it may not work for everyone because some people could be allergic to that one treatment that's why there are multiple treatments.

How do the cells in meiosis differ from the cells in mitosis?
AfilCa [17]

Answer:

C. Cells in meiosis have unique genetic information

Explanation:

Meiosis is the cell division that forms four daughter cells from one parent cell. It includes two successive divisions called as meiosis I and meiosis II. Crossing over during prophase I of meiosis I imparts new gene combinations to the daughter cells of meiosis. Hence, daughter cells formed by the end of meiosis have some new gene combinations, that is, unique genetic information.

What kinds of traits do not evolve through natural selection?
Harrizon [31]

Natural selection doesn't favor traits that are somehow inherently superior. Instead, it favors traits that are beneficial (that is, help an organism survive and reproduce more effectively than its peers) in a specific environment. Traits that are helpful in one environment might actually be harmful in another.

(one again, I hope this helps ^^)

Construct a concept map that shows how a population of bacteria can develop resistance to antibiotics.
Vsevolod [243]

The attached picture shows how bacteria gain antibiotic resistance. Firstly, a few individuals attain a beneficial mutation in their genetic material that accords them the capability to survive in an antibiotic. The individuals are hence able to survive and reproduce more than those individuals without the mutation. There is, therefore, a genetic shift in the population in favor of the resistant genotype. After generations, the whole population becomes antibiotic resistant.
