“A well known biologist stated that the life history of an organism can be summed up as gametic fusion, equational division and reductional division.” Comment.
Answer
The given statement is correct on the basis of the following facts :

1. The gametic fusion takes place at the time of fertilisation when sperm and ovum fuse to form a diploid zygote.

2. The zygote is divided by mitotic division during its embroynic life and post embryonic life to form a well developed individual.

3. A mature individual produces gametes by gametogensis. Reductional division takes place at this stage and results in the formation of haploid gametes.
