Recall Mendels law of segregation for autosomal alleles D and d and consider the behavior of homologous chromosomes in meiosis.

Biology
1 answer:
givi [52]3 years ago
8 0

Answer:

D

Explanation:

Homologous chromosomes are similar but non-identical chromosomes received from each parent. They are non-identical in the sense that they may contain different alleles for the same gene. For example, in this case, D and d alleles on each homologue. These homologous chromosomes are usually involved in meiotic division, which occurs in a two-step division process; Meiosis I and II.

In meiosis I, homologous chromosomes separate/pulls apart, specifically during the anaphase stage. Alleles D and d borne on the HOMOLOGOUS pair of chromosomes are separated in the process with each of them going to either pole of the cell, according to Mendel's law of segregation.

If the number of photosynthetic organisms on the earth decreased drastically, which would happen as a result?
IgorLugansk [536]
Photosynthetic organisms use the process of photosynthesis to produce their energy. During this process they also take in carbon dioxide and release oxygen. If there were less of such organisms, there would be more carbon dioxide  and less oxygen in the atmosphere.

NeX [460]
In 1668, Francesco Redi, an Italian scientist, designed a scientific experiment to test the spontaneous creation of maggots by placing fresh meat in each of two different jars. ... Redi successfully demonstrated that the maggots came from fly eggs and thereby helped to disprove spontaneous generation.

If you sorted 200 flies by eye color and body color, how many whole flies out of that 200 would you expect to exhibit each of th
mafiozo [28]

9:3:3:1 is the ratio.

From the given data,

We have a 9.8 two, ratio since we have 49/5, 15/5, 18/5, and 5/5.

This ratio resembles nine a little bit, which is what we inferred from the opposition's score.

When the two relevant genes exhibit independent assortment, this is the result. Therefore, the chromosomes/genes are not connected.

We are finally getting a ratio of 9:3:3:1

In flies, two possible outcomes for the body color phenotype is black and brown.

Whereas in eye color we have white eye and red eye.

Here, white eye is recessive and red eye is dominant

<h3>What does the independent assortment law entail? </h3>
  • According to Mendel's law of independent assortment, the alleles of two or more distinct genes are independently selected into gametes.
  • In other words, an allele for one gene does not affect the allele for another gene that a gamete acquires.

<h3>Where can I find independent assortment?</h3>
  • Meiosis I of gamete production, when homologous pairs line up in random orientations at the center of the cell as they prepare to split, provides the physical foundation for the law of independent assortment.
