Will a brown eyed husky parents produce blue-eyed pups?
If the parents are homozygous dominant in their brown-eye genes, then no. If one parent is homozygous dominant and one is heterozygous dominant, then no. If both parents are heterozygous dominant, then they have a one in four chance of producing a blue-eyed puppy. Brown is the dominant eye color and blue is the recessive eye color. In other words, you kind of have to know about the parents’ background. Do they both have a history of blue-eyed parents and/or grandparents? If both dogs come from brown-eyed lines, it’s unlikely they possess the recessive blue-eye gene. Basically: XX = homozygous dominant Xx = heterozygous dominant Cross 1: Two homozygous dominant parents Parent 1: XX Parent 2: XX Offspring Genotypes: XX, XX, XX, XX Cross 1 results in four brown-eyed puppies, because the brown-eye dominant gene is the only one present in either parent. Cross 2: One heterozygous dominant parent, one homozygous dominant parent. Parent 1: Xx Parent 2: XX Offspring Genotypes: XX, XX, Xx, Xx Cr
