प्रश्न
How does the progeny formed from asexual reproduction differ from those formed by sexual reproduction?
Advertisements
उत्तर १
| Progeny formed from asexual reproduction | Progeny formed from sexual reproduction |
| Asexual reproduction does not involve the fusion of the male and the female gamete. Organisms undergoing this kind of reproduction produce offspring’s that are morphologically and genetically identical to them | Sexual reproduction involves the fusion of the male and the female gamete of two individuals, typically one of each sex. Organisms undergoing this kind of reproduction produce offspring’s that are not identical to them. |
| Offsprings thus produced do not show variations and are called clones | Offspring’s thus produced show variations from each other and their parents. |
उत्तर २
Production of offspring by a single parent without the formation and fission of gametes is called asexual reproduction. It involves only mitotic cell division that gives rise to the daughter cells which are genetically identical to the parent cell. Sexual reproduction is the production of offspring by two parents, male and female. It involves meiotic cell divisions producing haploid nuclei, which, on fusion, produce offspring that are genetically different from their parents.
