Identifier	Name	Description
WBPhenotype:0000206	autosomal nondisjunction meiosis	A non-sex chromosome fails to segregate away from its homologous chromosome, resulting in gametes with no or extra copies of the non-sex homolog.
WBPhenotype:0001664	X chromosome nondisjunction	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.
WBPhenotype:0001633	lethal gamete	Animals produce ova/sperm that contain lethal factors as a result of chromosomal disjunction defects.
