What is a pedigree in biology?</h3>
A pedigree reveals the connections between family members and identifies the members of a family who have particular genetic pathogenic variations, features, and diseases as well as their current health. A family's pedigree might reveal how diseases are passed down through the generations.
<h3>
How do you determine if a pedigree is sex-linked?</h3>
They can be identified by notation; in a sex-linked pedigree, the majority of the affected individuals will be males, and the female carriers are often indicated by a half-shaded circle.
<h3>
