Question

Which is not true for haplodiploid sex determination?

• A. It is reported in honey bees.
• B. In this type, the male produces sperms by meiosis.
• C. They do not have a father and thus cannot have sons.
• D. In this type, the unfertilized egg develops as a male by means of parthenogenesis.

Answer 1

Answer: (B)

Haploid diploid sex determination process has one of the individual as haploid (male) and the other as diploid (female). Honey bees follow this pattern of sex determination. The males are haploid developed by process of parthenogenesis and produce gametes by process of mitosis. The females are diploid and the queen produces gametes by meiosis process.
