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