Zoology - Principles of Inheritance and Variation Question with Solution | TestHub
In which of the following mechanism of inheritance, male will be genotypically similar to of a female organism?
Options:
Answer:
Solution:
Sex-determination of Honey bee:
The sex-determination in honey bee is based on the number of sets of chromosomes an individual receives. An offspring formed from the union of a sperm and an egg develops as a female (queen or worker). And an unfertilized egg develops as a male (drone) by means of parthenogenesis. Thus genotypically male will be similar to females.This means that the males have half the number of chromosomes than that of a female. The females are diploid having 32 chromosomes and males are haploid, i.e., having 16 chromosomes. This is called as haplo-diploid sex-determination system and has special characteristic features such as the males produce sperms by mitosis.
