What proportion of the offsprings obtained from cross AABBCC X AaBbCc will be completely heterozygous for all the genes segreated independently?(Please explain in detail with the cross) (a)1/8 (b)1/4 (c)1/2 (d)1/16

answered-by-expert Expert Answer

Parents- AABBCC ×  AaBbCc

Gametes – ABC, ABC, ABc, AbC, Abc, aBC, abC, abc

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 correct answer is option A- '1/8'.
