Answer:
Meiosis is a reductional division. The diploid parent gametes are reduced to the haploid offsprings. It involves the exchange of genes between homologous chromosomes. The homologous chromosomes pairs by crossover are known as synapsis and exchange the chromosomal segment which causes genetic recombination.These variations in the offsprings make organisms more adaptable to the environment and these have a definite role in evolution.
So, the correct answer is option B.
