πŸ•·οΈ Genetic Diversity

The genetic diversity between organisms is accounted for by variation in DNA. Even a tiny difference in DNA can result in a lot of variation. What’s more, even identical DNA can still result in variation due to certain genes being active and others not. Is it visible that these two have largely identical DNA?

 

 

Nope. Yet when compared to bacteria or an imaginary alien, those two above definitely look more closely related. So the similarities between humans’ DNA and chimps’ DNA cause the visible and functional (phenotypical) similarities such as limbs, eyes, mouth, etc. while the differences in DNA result in the phenotypical differences such as hair thickness, facial features and so forth.

 

This knowledge has been used for a very long time by humans to manipulate wild plants and animals in order to make them somehow useful. People selectively breed plants and animals to change their genetic profile, so that certain traits are…
