A double-helix configuration can make a copy of the original. To achieve this, it unzips itself thereby exposing the two sides of the original double helix. This results in the creation of two identical chromosomes where there was only one. […]

When it comes to determining gender, male chromosomes play a crucial rule. Although true in case of humans, this is not universal. […]

There are three assumptions we need to make to study behavioral genetics: first, that we can quantify behavior; second, that we can identify environmental factors; and third, that we can determine genetic factors. […]

There are undeniable links between human behavior and genes. However, behavioral traits are quite complicated, and are a result of a large chain of many genes, as well as environmental characteristics. […]

With genetic fingerprinting, scientists can identify an individual from the genetic material in just a single cell. […]

Gregor Mendel came up with four laws with regard to genetics. They speak of the existence of genes and identify them as responsible for carrying specific traits. […]

Gregor Mendel conducted a series of experiments on pea plants, focusing on their distinctive traits. As a result of his findings, he postulated four basic laws of classical genetics. […]

Gregor Mendel charted his way from being a monk to a scientist. He conducted groundbreaking experiments in the field of genetics that finally led him to propose the basic laws of classical genetics. […]

Classical genetics studied genes at the level of organisms and their traits. However, the ancient theory of spontaneous generation seemed to threaten this idea. […]
