What advantage does the process of crossing over bring to the reproductive process?

Answer 1

It produces offspring with genetic variation, different from the parent gametes. This is opposed to asexual reproduction where identical offspring are the product. This is the diversity that is created on the levels of genotype and phenotype.

Answer 2

Crossing over during meiosis increases genetic diversity by swapping genetic material between homologous chromosomes. This leads to new combinations of alleles in the offspring, promoting variation within a population. This variability is important for evolution and adaptation to changing environments.

Answer 3

it allows more genetic diversity in the plant species and because of this the species is more resistant to a changing environment. This is because individual plants would have slightly different characteristics which may be beneficial if there is a change in their environment.
