Question

Meiosis is a process used by many organisms but not all organisms. What organisms or
habitats would make mitosis a better reproductive option than meiosis?

Answer 1

Meiosis does not occur in archaea or bacteria, which reproduce via asexual processes such as mitosis or binary fission. ... Because the chromosomes of each parent undergo genetic recombination during meiosis, each gamete, and thus each zygote, will have a unique genetic blueprint encoded in its DNA.
