Definitions:

Genes

Units of heredity that carry information from parents to offspring, influencing traits and characteristics.

X-Linked

A gene carried on the X chromosome. If a male inherits an X-linked recessive trait from his mother, he expresses that trait because the Y from his father has no counteracting gene. Females are more likely to be carriers of X-linked traits but are less likely to express them.

Epigenetic

The study of heritable changes in gene expression that occur without alterations in the DNA sequence, influenced by environmental factors.

Polygenic

Pertaining to or involving multiple genes, especially in relation to the genetic basis of complex traits and characteristics.
