Deeply Blue

Deeply Blue
Biology. Test Cross (I deeply value whether the explanations are given as well)?

In humans, the gene of non-blue eyes (brown, hazel, or gray) is dominant over the gene for blue eyes. Mr. Jones has brown eyes and your wife has hazel eyes. They have 5 children, three of which have blue eyes. What are the genotypes of the parents? How would you explain the eye color of children? Thank you.

to this question, we conclude that both parents are heterozygous for eye color. for example, when we do a test cross to determine the genotype of the parents, the first thing we can say that B is dominant eye color and B is recessive eye color, when we do an intersection test for Bb x Bb We can see that one of the springs is not that BB codes for color recessive blue eyes. if one parent is homozygous for eye color, for example, BB x Bb then the cross does not show off the spring with blue eyes. by We can therefore conclude that both parents are heterozygous … and Bb and BB for men and women. the color of the eyes of children can be explained as a proportion 3:1, since only 1 in 4 children in the test cross can have blue eyes, and combinations of the cross test are as follows BB, Bb, Bb, bb.
