In the figure, the green and gold boxes represent the offspring of parents that are heterozygous at locus 1 (Aa) and locus 2 (Bb). Which of the boxes represent repulsion double heterozygote offspring?

Ab aB ab AB Ab aB ab D 0 Click to view larger image O a. the blue boxes O b the green boxes OC the gold boxes O d. None of the boxes represent repulsion double heterozygotes.

Solution

Ans.

Coupling refers to the linkage of two dominant or two recessive alleles, whereas repulsion indicates that dominant alleles are linked with recessive alleles.The green box shows Ab and aB genotypes indicating repulsion doble heterozygte offspring.

b) The green boxes represent repulsion double heterozygote offspring.
