WormMine: Phenotype WBPhenotype:0001664 X chromosome nondisjunction

• Description: The frequency of sex chromosome segregation is perturbed, resulting in the production of exceptional gametes (e.g. ova or sperm) and populations with a sex ratio altered from the rate of 1:500 as observed for control populations.

Identifier	Name	Description
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:0001631	nullo X gamete	Animals produce ova/sperm that contain no X chromosome in a nonmendelian segregation pattern.
WBPhenotype:0001583	XXX progeny	Animals segregate progeny with 3 X chromosomes.
WBPhenotype:0001665	low incidence male progeny	Lower numbers of male progeny occur in the population compared to control populations. In C. elegans, the low incidence of males phenotype in a self-fertilizing hermaphrodite population is a result of an decrease in X chromosome nondisjunction.
WBPhenotype:0001632	diplo X gamete	Animals produce ova/sperm that contain 2 X chromosomes.

WBPhenotype:0001174	chromosome disjunction defective	Chromosomes fail to segregate away from their homolog, resulting in gametes with no or extra copies of the chromosome.
