So, this post is mainly for her and many other inquisitive people out there wondering similar things. I have been having so many thoughts on this and the following is a small gist of my thoughts penned down.

Replication can be done in the lab too but the issue is that there is not much understanding about gene regulation and reproduction. Most of us know about Dolly, the sheep which was the first mammal to be cloned, using the diploid nucleus from an adult tissue. Here
