The reproduction is the phenomenon which involves the production of an offspring by particular individuals or individuals to propagate there species. Reproduction are of two types:
1. Asexual reproduction: In asexual reproduction, they does not involve the fusion of gametes. The unicellular organism reproduce mainly by binary fission. In this, a single cell divides into two daughter cell. The daughter cell completely resembles their parent. It involves only one parent.

A. Scientists discovered chromosomes and DNA.

When scientists discovered chromosomes and DNA, they were able to see how Mendel's observations made sense in the context of DNA and chromosomes.
