According to analysis the children's with white eyes will having white eye parents is the children responsible for white eye dominant. Why? |
|
Answer» Answer: Genetics. The parents with the more dominant allele will influence the eye color of a child. I'm not sure if white is an eye color, but blue EYES are the less-dominant alleles in comparison with brown. So, if one PARENT has brown (with no trace of blue eyes in the PREVIOUS generations) and the other has blue, the child is likely to have blue eyes. however, when he/she has a child, she/he MIGHT be able to give his/her blue eyes if the partner ALSO has blue eyes. I hope this helped... :) (Melanin is a pigment that influences this) Explanation:
