Question

what process is important for creating genetic variability among organisms that reproduce primarily by asexual means?
○ crossing - over
○ fertilization
○ meiosis
○ mutation

Explanation:

Crossing - over occurs during meiosis in sexually - reproducing organisms and results in the exchange of genetic material between homologous chromosomes, creating genetic variability. Fertilization combines gametes but doesn't directly create new genetic combinations like crossing - over. Selection acts on existing genetic variation. Mutation creates new alleles but is not the main process for creating genetic variability in sexual reproduction compared to crossing - over.

Answer:

Crossing over
