<span>its meiosis 2 because in this separation of sister chromatids occur which is very similar to mitosis..</span>

According to McGraw-Hill, meiosis II and mitosis are similar because during both processes, sister chromosomes split along the center of the cell. During both meiosis II and mitosis, the sister cells line up down the middle of the cell and the spindle fibers pull them apart. The result is daughter cells that are genetically identical to one another.

When is selective breeding okay and when is it not? Provide evidence.
jonny [76]

Answer:

Farmers have been using selective breeding for improving their crop qualities and producing animals with better characteristics.

improved so that mankind can benefit from it.

Selective breeding is not okay on a bigger level where it might eradicate the natural varieties of plants and animals completely.  When done on a larger level, the wild-type traits of plants and animals will change and be removed completely. This will lead to lesser genetic diversity.

How does the recesive sickle-cell allele stay in the gene pool
Zina [86]

Answer:

Because natural selection selects for it. Thus it persists.

Explanation:

You have to understand heterozygote advantage. Basically, it's where heterozygotes have an advantage over homozygotes. In the case of sickle cell disease, heterozygotes have an advantage, and natural selection favors whatever is advantageous. Thus, because heterozygotes each have one recessive sickle-cell allele, as natural selection favors the heterozygotes, the recessive sickle-cell allele persists and remains in the gene pool.

The sickle-cell allele produces a serious blood disease in homozygous recessive individuals. why doesn't natural selection elimi
icang [17]

No, the sickle-cell anemia allele won't be eliminated by natural selection.

Sickle-cell anemia trait is controlled by a single gene and the allele (S) for sickle-cell anemia is a harmful autosomal recessive.

It is caused by a mutation in the normal allele (A) for hemoglobin (a protein on red blood cells).

Heterozygotes (AS) with the sickle-cell allele are resistant to malaria, a deadly tropical disease. It is common in many African populations.

In these areas, (S) carriers have been naturally selected, because their red blood cells, containing some abnormal hemoglobin, tend to be in sickle shape when they are infected by the malarial parasite.

Therefore, they are more likely to survive and reproduce. This keeps the S allele in the gene pool.
