The diagram shows a diploid cell with two homologous pairs of chromosomes.

AFTER crossing over occurs and due to independent assortment of alleles, the possible allele combinations that could be found in gametes produced by meiosis are-


A; B; a; b


AB; Ab: aB; ab


AA; BB; aa; bb


AB; AB; ab; ab

Answer: AB; Ab; aB; ab

Reason: Meiosis produces haploid gametes. With two independently assorting loci (and crossing over allowing recombinants) all four allele combinations — AB, Ab, aB and ab — can be formed.
