Solution


Q.

What is the disadvantage of parthenogenesis
1 Wastage of germplasm  
2 Retention of genotype  
3 Lack of adaptability  
4 Variety in population  

Ans.

(3)

Since there is no fertilisation of gametes in parthenogenesis, there will be no crossing over of genes. This hence causes no variations in the generations. Which makes it difficult for the offspring to adapt to the changing environmental conditions.
