Which is not true for haplodiploid sex determination? a)It is reported...
Haplodiploid sex determination is a unique mechanism of sex determination observed in certain organisms, particularly in insects such as honey bees. It is characterized by the fact that males develop from unfertilized eggs, while females develop from fertilized eggs. Let's go through each option and understand why option B is not true for haplodiploid sex determination.
a) It is reported in honey bees:
This statement is true. Haplodiploid sex determination is indeed reported in honey bees. In honey bee colonies, the queen bee mates with multiple drones (males), and the fertilized eggs develop into females, while the unfertilized eggs develop into males.
b) In this, male produces sperms by meiosis:
This statement is not true. In haplodiploid sex determination, males develop from unfertilized eggs and are haploid, meaning they have half the number of chromosomes compared to females. Therefore, they cannot produce sperm through meiosis, as meiosis is a process that produces haploid cells from diploid cells.
c) They do not have a father and thus cannot have sons:
This statement is true. Haplodiploid organisms, such as honey bees, do not have a father in the traditional sense. Males develop from unfertilized eggs and are haploid, so they only have a mother. As a result, they cannot have sons, but they can have daughters.
d) In this, unfertilized egg develops as a male by means of parthenogenesis:
This statement is true. Haplodiploid organisms, including honey bees, can develop males from unfertilized eggs through a process called parthenogenesis. Parthenogenesis is a form of reproduction where an egg develops into an individual without fertilization. In the case of haplodiploid sex determination, unfertilized eggs develop into males, while fertilized eggs develop into females.
Therefore, the correct answer is option B) In this, the male produces sperms by meiosis. This statement is not true because in haplodiploid sex determination, males are haploid and do not produce sperm through meiosis.
