Question

Parthenogenesis is connected with

• A. Sexual reproduction
• B. Asexual reproduction
• C. Regeneration
• D. Budding

Answer 1

The correct option is B Asexual reproduction

Parthenogenesis is the development of an embryo from an unfertilized egg or if a spermatozoa does penetrate the egg, there is no union of male and female pronuclei. It is a mode of asexual reproduction. On the basis of divison, it is of two types- apomictic parthenogenesis and automictic parthenogenesis.

In apomictic parthenogenesis, the mature egg cells are produced by mitotic divisions, and these cells directly develop into embryos. The offsprings produced are full clones of the mother.

In automictic parthenogenesis, the mother cell undergoes meiosis and produces haploid offspring which are half clone of the mother cell.

So, the correct answer is option B.
