Solution

The correct option is B Recombination of alleles
Chromosomal crossover is the exchange of genetic material between 2 homologous chromosomes that results in recombinant chromosomes during sexual reproduction. The effect is to shuffle the alleles on parental chromosomes so that the gametes carry combinations of genes different from either parent.
So, the correct option is 'Recombination of alleles'.
