Crossing-Over and Genetic Diversity
Which of the following statements best describes how crossing-over during meiosis increases genetic diversity?
A
During interphase, DNA replication duplicates genetic material but does not lead to crossing-over.
B
During metaphase II, chromosomes align at the cell equator without exchanging genetic material.
C
During cytokinesis, cell division separates the cytoplasm but does not alter genetic content.
D
During prophase I, homologous chromosomes exchange segments, producing new allele combinations in the resulting gametes.
