Although Paolo and David are identical twins, they have traits that are different from each other such as their height. Which of the
following statements best describes how the process of crossing over during meiosis leads to their genetic diversity? A. During prophase I, DNA replication takes place and homologous chromosomes trade places with each other before lining up in
preparation for metaphase I.
B. During prophase I, DNA segments are exchanged between homologous chromosomes resulting different combination of
alleles.
C. During prophase II, DNA segments are exchanged between homologous chromosomes resulting different combination of
alleles.
D. During prophase II, sister chromatids separate from each other and as they travel to opposite ends of the cell, DNA segments of
nearby chromosomes are exchanged.
