Vedclass · Answer

(C) In sex determination,female heterogamety occurs when the female produces two different types of gametes,typically denoted as $ZW$ and $Z$ (or $ZW$ and $ZO$).This mechanism is characteristic of birds $(Aves)$,some reptiles,and some butterflies.In humans ($XY$ type) and grasshoppers ($XO$ type),the male is the heterogametic sex.In honey bees,sex determination is based on the number of sets of chromosomes (haplo-diploidy),where the queen is diploid and the drone is haploid.Therefore,the correct answer is birds.

In which of the following organisms is female heterogamety observed in sex determination?
