The ages of most specimens were known, inasmuch as the specimens were used in studies of growth as well as gametogenesis. |
Meiosis is the component of gametogenesis responsible for the segregation of homologous chromosomes into haploid gametes. |
During gametogenesis the microgametocyte replicates its genome three times in order to produce eight motile microgametes. |
Flies homozygous for such hypomorphic mutations reach adulthood, but often exhibit defects during the proliferative stages of gametogenesis. |
Suppose that, during meiosis in the female, gametogenesis occasionally goes wrong, and the two X chromosomes fail to disjoin. |
Pond-breeding urodeles, such as A. texanum, exhibit postnuptial gametogenesis. |
