What would happen if crossing over no longer occurred in human meiosis?

Question

Quizplus · Accepted Answer

Crossing over during meiosis is a critical process that increases genetic diversity by exchanging DNA between homologous chromosomes. If crossing over did not occur, the genetic variation among offspring would be significantly reduced, leading to a decrease in the population's ability to adapt to changing environments or resist diseases. Independent assortment, the separation of chromosomes during anaphase, and the determination of sex (male or female) would not be directly affected by the absence of crossing over.
