Question

An irregular mode of reproduction resulting in the development of an embryo without fertilization is called
1.Parthenogenesis 2.Apogamy 3.Sporophytic budding
Select the correct answer using the code given below.
A) 1 only B) 2 only C) 2 and 3 only D) 1, 2 and 3

Answer 1

Answer:

In parthenogenesis formation of fruit occurs without fertilisation.

In apogamy haploid (n) vegetative cell forms embryo without gametogenesis and fertilisation.

In sporophytic budding diploid (2n) vegetative cell forms embryo from bud by vegetative reproduction.

Thus, all of these processes are irregular modes of reproduction.

So, the correct answer is option D.
