They help to repair damaged cells

Answer 1

The importance of homologous chromosomes in prophase I of meiosis is that they contribute to genetic variety. This is achieved through the process of crossing over, where homologous chromosomes exchange genetic material, leading to the creation of new combinations of alleles in the resulting gametes. This genetic variation is important for evolution and the adaptation of species to changing environments.
