Recombination is important during meiosis primarily because it creates gametes with new combinations of genes to increase diversity in offspring. During meiosis, specifically in prophase I, homologous chromosomes undergo crossover events, allowing segments of DNA to be exchanged between paired chromosomes. This process results in genetic variation among the gametes produced, which ultimately contributes to the genetic diversity of offspring when fertilization occurs. Increased diversity can enhance a population's adaptability and resilience in changing environments.
Why is recombination is so important during meiosis?
to create new variation in cells during mitosis
creates somatic cells with different combinations of alleles in order to produce variation
creates gametes with new combinations of genes to increase diversity in offspring
to create new stem cells that undergo uncontrolled cell reproduction
