How does random fertilization add to the genetic variation?
A)Nonsister chromatids exchange gene segments to produce new combinations of maternal and paternal genes.
B)Fusion of sperm and ovum, each having a unique combination of chromosomes, introduces further variation.
C)Homologous pairs of chromosomes sort into daughter cells independently of the other pairs.
