Vedclass · Answer

(B) During meiosis,specifically in the pachytene stage of prophase-$I$,the process of crossing over occurs between non-sister chromatids of homologous chromosomes.This process leads to the exchange of genetic material,resulting in new combinations of genes,which is known as recombination.Recombination is the primary mechanism responsible for genetic variation and the emergence of new characteristics in the offspring compared to their parents.Linkage refers to the tendency of genes to be inherited together,which reduces variation,and segregation ensures the separation of alleles,but recombination is the specific event that creates new genetic combinations.

Which event during cell division is responsible for the emergence of new characteristics in the next generation of organisms?
