The number of taxa exhibiting asexual reproduction is drastically reduced in the higher plants (angiosperms) and higher animals (vertebrates) as compared with lower groups of plants and animals. Analyse the possible reasons for this situations.

Text Solution

Verified by Experts

Asexual reproduction does not produce new combinations or variation. Sexual reproduction produces a lot of variations due to crossing over, chance recombination, random fertilisation and independent assortment. Angiosperms and vertebrates have complex structural organisation and longer life span. They have adapted sexual reproduction for better survival
