Answer:
The loss of fur is a protection mechanism for the epithelium that covers us, over the years this method of protection was replaced by the protection provided by melanocytes with their melanin, therefore people who had a low presence of melanin could not survive in the evolution.
Explanation:
The presence of melanocytes and melanin in the skin is what protects it against ultraviolet radiation, over time the human being was affected by solar radiation, thus being one of the causes of bipedalism.
In those humans where melanin is defective or a small number of melanocytes are more predisposed to suffer epithelial pathologies today.
Human evolution then led to hair loss and increased epithelial tonality, causing those who could not have this phenotypic quality to be extinct or deceased.

Answer:
<h2>
All the gametes are 25%; SY(25% so on) Sy, sY, and sy .
</h2>
Explanation:
Spherical shape (S) is dominant over dented shape(s), so S is dominant over s;
Yellow (Y) is dominant over white color (y), so Y is dominant over y.
Here as given, parent is heterozygous for both parents.
so its genotype is= SsYy
Gametes formation follow both law of segregation and law of independent assortment:
So, 25% of gametes are SY
25% of gametes are Sy
25% of gametes are sY
25% of gametes are sy.
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.
