Sexual reproduction results in an increase in genetic diversity because:
A. during prophase I, genes that are
paternally and maternally derived are
recombined on the chromosomes so that the
gametes have chromosomes that are
different from the parents' chromosomes.
B. during metaphase I, the bivalents line up in
a random orientation so that gametes inherit
a random set of maternally and paternally
derived chromosomes.
C. during fertilization, the gametes that fuse
are random so that a large number of
chromosomal combinations are possible in
the new organism.
D. of both recombination during prophase I
and random orientation of bivalents during
metaphase I.
E. All of these choices are correct.
