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-


AB; Ab: aB; ab


A; B; a; b


AA; BB; aa; bb


AB; AB; ab; ab

AB; Ab; aB; ab

Explanation: Meiosis produces haploid gametes with one allele per gene. For two genes there are 2 × 2 = 4 possible allele combinations. Independent assortment (and crossing over) produces the four combinations AB, Ab, aB and ab. The other options are either single alleles, impossible diploid gametes (AA, BB, …), or only the parental types with no recombination.
