Why must the life cycle of sexually reproducing species alternate between haploid and diploid stages?
A)Meiosis must occur at some point in the life cycle to prevent a doubling of chromosomes in each generation.
B)Mitosis must occur at some point in the life cycle to prevent a reduction of chromosomes in each generation.
C)The diploid stage allows for genetic recombination.
D)Meiosis must occur at some point in the life cycle to prevent a reduction of chromosomes in each generation.
E)Haploid cells cannot grow independently of diploid cells.
