Erfðaþátta

Erfðaþátta is the Icelandic term for genes. Genes are the fundamental units of heredity, passed down from parents to offspring. They are segments of DNA, a complex molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all known organisms and many viruses. Each gene contains a specific sequence of nucleotides that codes for a particular protein or functional RNA molecule. These molecules, in turn, perform a vast array of tasks within the cell, ultimately determining an organism's traits.

The study of erfðaþátta falls under the domain of genetics. This field explores how traits are inherited and how genes are passed through generations. Humans, like all other living beings, have thousands of erfðaþátta organized into structures called chromosomes. These erfðaþátta interact with each other and with the environment to shape an individual's characteristics, ranging from physical attributes like eye color and height to predispositions for certain diseases. Understanding erfðaþátta is crucial for advancements in medicine, agriculture, and evolutionary biology.
