Question

mother has brown eyes and father have black eyes . the son has black eyes what is it​

Answer 1

Answer:

The most likely outcome is that the children have brown eyes. If both parents have brown eyes, but both are also carrying the recessive gene for blue eyes, then the ratio is expected to be 3 brown-eyed children for every 1 blue-eyed child. However, this is by no means certain.

The key to understanding genetic eye colors is that Brown is dominant and Blue is recessive, so it only takes one Brown gene to make a person’s eyes appear brown, but it takes two Blue genes to make a person’s eyes appear blue. Thus, a brown-eyed person may be carrying the recessive gene for blue eyes, which may be passed to their children. The expression of the genes that is visible, or can be observed and identified, is called the phenotype. There are many shades of eye colors (phenotypes), but there are only two genetic possibilities — brown and blue.
