In sexually reproducing organisms, an indiÂ­vidual receives one genome or one set of chromosomes (and hence genes) from male parent and a second genome or set of chromosomes from female parent.
Well, your genetic material known as deoxyribonucelic acid (DNA) is the reason. DNA is the hereditary material found in the nucleus of eukaryotic cells (animal and plant) and the cytoplasm of prokaryotic cells (bacteria) that determines the composition of the organism. DNA is found in the nucleus of every cell, and it is exactly the same in each cell. There is another type of genetic material found in cells and viruses known as ribonucleic acid (RNA). Structure and Function. DNA contains all the secrets that make you so awesome! So, it is super important that the cell keeps the DNA safe.
