why is genetic recombination important for species?
a) genetic recombination allows new genetic combinations and increases the genetic diversity in a population. this drives natural selection and evolution.
b) genetic recombination allows the genetic material of a cell to be copied before cell division, resulting in daughter cells that can undergo genetic recombination.
c) genetic recombination allows the best genes to be selected, ensuring that mutated genes arent passed on to offspring.
d) genetic recombination allows the genetic material to be expressed, creating both rna and proteins from a cells dna.

Explanation:

Genetic recombination shuffles genetic material, creating new combinations. This increases genetic diversity in a population. Higher genetic diversity provides more variation for natural - selection to act upon, which is crucial for evolution. Option B is about DNA replication before cell division, not the main role of genetic recombination. Option C is incorrect as genetic recombination doesn't specifically select the 'best' genes or prevent mutated genes from being passed on. Option D is about gene expression, not genetic recombination.

Answer:

A. Genetic recombination allows new genetic combinations and increases the genetic diversity in a population. This drives natural selection and evolution.
