WBPhenotype:0000688
|
sterile
|
Animals generate defective gametes, are otherwise unable to reproduce or they generate progeny that are unable to reproduce. |
WBPhenotype:0001175
|
high incidence male progeny
|
Higher numbers of male progeny occur in the population compared to control populations. In C. elegans, the high incidence of males phenotype in a self-fertilizing hermaphrodite population is a result of an increase in X chromosome nondisjunction. |
WBPhenotype:0001215
|
germ cell mitosis variant
|
Variations in the mitotic expansion of germ cell populations or in the appearance of nuclei during development in the premeiotic region of the germline compared to control. |
WBPhenotype:0000775
|
meiosis variant
|
Variations in the specialized nuclear and cytoplasmic divisions of a single diploid cell, whose specific outcome is the formation of four haploid daughter cells compared to control. Meiosis occurs during the formation of gametes. |
