Question

question 16 1 pts what main process in meiosis ensures genetic variation in the offspring? replication crossing over fertilization cytokinesis

Explanation:

Crossing - over during meiosis is the main process that ensures genetic variation. It involves the exchange of genetic material between homologous chromosomes. Replication just duplicates DNA, fertilization combines gametes but is not a meiotic process for variation within meiosis, and cytokinesis is cell - division related and not the main source of genetic variation in meiosis.

Answer:

B. crossing over
