Which two processes generate the most genetic variation in meiosis?
A.Crossing over and independent assortment
B.DNA replication and transcription
C.Mitosis and cytokinesis
D.Translation and mutation repair
Explanation
Core Concept
Crossing over creates recombinant chromatids by exchanging DNA between homologous chromosomes, while independent assortment produces many combinations of maternal and paternal homologs in gametes. Together they greatly increase genetic variation, but they do not guarantee that every individual gamete has a combination unique from every other gamete.
Correct Answer
ACrossing over and independent assortment
