Question

What proportion of the offsprings obtained from cross AABBCC Ã AaBbCc will be completely heterozygous for all the genes segregated independently ?

Answer 1

$\huge\mathbb\orange{Heya\:Mate..!}$

Since one parent is homozygous AABBCC the genotype formed will be only 1 type i.e. ABC. The other parent is heterozygous for all genes. About 1/8th or 12.5% of total offspring will be heterozygous at all three-locus. So the answer is '1/8'.
