Which one of the following statements about haplodiplontic life cycles is false?
A)For each gene,cells of the gametophyte stage have a single allele.
B)Spore mother cells produce haploid spores by meiosis.
C)The gametophyte stage produces gametes by mitosis.
D)The zygote is the only diploid cell in the sporophyte stage.
E)Mitosis occurs in both sporophyte and gametophyte stages.

The statement that "the zygote is the only diploid cell in the sporophyte stage" is false in haplodiplontic life cycles. In haplodiplontic life cycles, the sporophyte stage is also diploid and produces haploid spores through meiosis. The gametophyte stage is haploid and produces gametes by mitosis. Therefore, both the sporophyte and gametophyte stages undergo mitosis.
