Solution


Q.

Offspring formed by asexual method of reproduction have greater similarity among themselves because:

(i) Asexual reproduction involves only one parent.
(ii) Asexual reproduction does not involve gametes.
(iii) Asexual reproduction occurs before sexual reproduction.
(iv) Asexual reproduction occurs after sexual reproduction
1 (i) and (ii)  
2 (i) and (iii)  
3 (ii) and (iv)  
4 (iii) and (iv)  

Ans.

(1)

Offspring have greater similarity as only one parent is involved in asexual reproduction thus no gametes are formed. The basis of asexual reproduction is mitosis (division of a nucleus into two identical daughter nuclei). Each daughter nucleus has same genetic make up because of replication of parental DNA. The new offspring produced are called clones.
