Question

short note of parthenogenesis and parthenocarpy

Answer 1

Answer:

parthenogenesis is a type of asexual reproduction in which the offspring develops from unfertilized eggs. It is particularly common amongst arthropods and rotifers, can also be found in some species of fish, amphibians, birds, and reptiles, but not in mammals. Parthenogenetic development also occurs in some plants species, such as roses and orange trees.

Most animal species that reproduce parthenogenetically also display a phase of sexual behaviour and sexual reproduction. In most cases, parthenogenetic reproduction occurs when environmental conditions are favourable and there is plenty of food that can sustain the generation of large numbers of individuals in a short period of time.

Answer 2

Explanation:

Parthenocarpy is the production of fruits from unfertilized ovules in plants. The fruits produced by parthenocarpy do not contain seeds. For example, seedless watermelon and oranges. Parthenogenesis is a type of reproduction in which the ovum develops into an individual without fertilization.
