Q1 of 49 Page 1

A few statements describing certain features of reproduction are given below:

i. Gametic fusion takes place


ii. Transfer of genetic material takes place


iii. Reduction division takes place


iv. Progeny have some resemblance with parents


Select the options that are true for both asexual and sexual reproduction from the options given below:


In Sexual reproduction, gamete fusion occurs and the genetic material transfers from both the parents after which reduction division (meiosis) takes place to reduce the diploid body (2n) into a haploid body(n). The progeny resembles the parents.


In asexual reproduction fusion of gametes does not take place, genetic material transfers from the parent body to the new born but no reduction division takes place. The progeny is similar to the parent.
