Question

Arrhenotoky is related to
(a) Parthenogenesis
(b) Wax formation
(c) Both A and B
(d) None of these

Answer 1

Hint: Arrhenotoky refers to the development of the young individual without any process of fertilization. It occurs in haploid organisms where the development of the haploid male occurs through an unfertilized egg.

Complete answer:
Sexual reproduction follows the process of fertilization of an egg by a sperm. The fusion of both male and female gametes results in the formation of a zygote which develops to become an embryo. Whereas parthenogenesis is the formation of an individual, from an unfertilized egg ultimately developing into an embryo. Parthenogenesis is a form of asexual reproduction. Parthenogenesis can be haploid or can also be diploid. If the parthenogenesis is haploid it is known to be Arrhenotoky. The haploid egg, unfertilized by a sperm gives rise to an embryo. The haploid parthenogenesis process generally gives rise to an embryo which develops into a male.

Additional Information:
- It may occur that animals that undergo parthenogenesis division may we come incapable of sexual reproduction it may also occur that they tend to switch between sexual and asexual modes of reproduction.
- The organisms which can switch between the sexual and sexual modes of reproduction generally follow the sexual mode of reproduction and fewer stimuli or any stressful conditions post them to go for the asexual mode of reproduction.
- No modification of genes also known as mutation occurs in the case of parthenogenesis hence the offspring produced parthenogenesis is exactly a clone of the parent.
- Parthenogenesis can mainly be seen in lower plants some fishes, some reptiles, and other organisms who may not have any sex chromosomes.
So, the correct option is, ”Parthenogenesis”.

Note:
- If by parthenogenesis, female gamete formation occurs then that process is called to be thelytoky and if it leads to male gamete formation it is known as arrhenotoky.
- As parthenogenesis does not offer any genetic modification on meditation the offspring may also inherit all the diseases that the parent has.
