When two parents participate in reproductive process and also involve fusion of their gametes, it is called

The offsprings formed by asexual reproduction method have greater similarity among themselves because:
(i) asexual reproduction involves only one parent
(ii) asexual reproduction involves two parents
(iii) asexual reproduction involves gametes
(iv) asexual reproduction does not involve gametes
(a) (i) and (ii)
(b) (i) and (iii)
(c) (ii) and (iv)
(d) (i) and (iv)

Offspring formed by sexual reproduction exhibit more variation than those formed by asexual reproduction because
(a) Sexual reproduction is a lengthy process
(b) Gametes of parents have qualitatively different genetic composition
(c) The genetic material comes from parents of two different species
(d) Greater amounts of DNA is involved in sexual reproduction

Given below are few statements about sexual reproduction.
Choose the correct set of statement(s).

1. Involves fusion of male and female gametes.

2. Females usually produce more gametes when compared to males.

3. It is an elaborate, complex and slow process.

4. Offsprings are genetically identical among themselves but different from parents.
