WebWhat is the first stage of meiosis during which a cell is considered haploid? Prophase II How is oogenesis different from spermatogenesis? Oogenesis results in one egg cell, … WebOne very important event in meiosis is crossing over, which occurs between prophase and metaphase I. Crossing over increases genetic variation. The haploid cells produced through meiosis are otherwise known as gametes. Gametes combine during sexual reproduction which also increases genetic diversity .
http://www.waynesword.net/lmexer8.htm WebMost fungi and algae employ a life-cycle strategy in which the multicellular “body” of the organism is haploid. During sexual reproduction, specialized haploid cells from two individuals join to form a diploid zygote. The zygote immediately undergoes meiosis to form four haploid cells called spores ( Figure 7.2 b ).
