Recombination

Vedclass · Answer

(B) The correct answer is $B$. Genetic variation in sexually reproducing organisms primarily arises from the reshuffling of genes. This occurs through three main processes: $1$. Independent assortment of chromosomes during meiosis. $2$. Crossing over,which leads to the exchange of genetic material between homologous chromosomes. $3$. Random fertilization of gametes. Collectively,these processes are referred to as recombination. While mutations and genetic drift also contribute to variation,recombination is the most frequent and consistent mechanism driving variation in a sexually reproducing population.

Which is the most common mechanism of genetic variation in the population of a sexually reproducing organism?
