A cross between two heterozygous parents for blue eye color will result in what phenotypic ratio for their offspring?
|
|
1:2:3
|
|
|
1:2
|
|
|
1:2:1
|
|
|
3:1

Explanation:
Detailed explanation-1: -The expected genotype ratio when two heterozygotes are crossed is 1 (homozygous dominant) : 2 (heterozygous) : 1 (homozygous recessive). When a phenotypic ratio of 2 : 1 is observed, there is probably a lethal allele.
