Vedclass · Answer

(A) Crossing over occurs during the $pachytene$ stage of $prophase-I$ of $meiosis$. It involves the exchange of genetic material between non-sister chromatids of homologous chromosomes. This process leads to the recombination of genes,which results in genetic variation among offspring. Genetic variation is the raw material for natural selection and is essential for the process of evolution,as it allows populations to adapt to changing environments over generations.

Genetic variation produced in species due to crossing over is an important process for which of the following?
