The intersex is produced by ________________(a) Fusion of a male and female zygote(b) Loss of X chromosome from some cells(c) Loss of Y chromosomes from some cells(d) Gain of X or Y chromosome due to non-disjunctionI have been asked this question in an online quiz.My enquiry is from Sex Determination in Mammals in section Chromosomes and Sex Determination of Cytogenetics

Answer»

Right choice is (c) LOSS of Y chromosomes from some cells

The best I can explain: Intersex has the combination AA+ XO/XY. PRESENCE of Y chromosomes develops male CHARACTER so AA+XY cells are male. ABSENCE of Y gives female characters so AA+XO gives female, this is due to loss of Y chromosome from these cells. Overall it results in intersex.
