It could be said that males are able to provide gametes with more genetic diversity than females for reproduction. One main reason would be

A. males provide more genes in sperm than females provide in eggs
B. crossing over occurs more often in the formation of sperm than in eggs
C. spermatogenesis in males results in four fictional sperm while oogenesis in females results in only one egg and three structures that contain genetic information that is lost when they disintegrate
D. sperm that contain a recombination of genes are usually more successful in fertilizing


Ans: C. spermatogenesis in males results in four fictional sperm while oogenesis in females results in only one egg and three structures that contain genetic information that is lost when they disintegrate
