Answer to Question #227704 in Cell Biology for Joana

Question

why is crossing over and formation of haploid cells in meiosis important in the survival of every species?

Answer 1

The crossing over or recombination of genes which occurs in meiosis rearranges the alleles present in each chromosome of a homologous pair, allowing the mixing of paternal and maternal genes, either of which can be expressed in the resultant offspring.
