D
Formation of identical daughter cells
검증된 단계별 안내1
Understand that crossing over occurs during prophase I of meiosis, where homologous chromosomes pair up and exchange segments of genetic material.
Recognize that this exchange of genetic material between homologous chromosomes results in new combinations of alleles, which increases genetic diversity.
Note that the primary purpose of meiosis is to produce gametes (sperm and eggs) with half the number of chromosomes, not to produce ATP or identical daughter cells.
Identify that the increased genetic variation due to crossing over is crucial for evolution and adaptation, as it contributes to the genetic differences among offspring.
Conclude that the correct result of crossing over during meiosis is increased genetic variation in gametes, which is essential for the diversity of traits in a population.
