Definitions:

Dominant Traits

Genetic characteristics that are expressed in an organism's phenotype even when only one copy of the gene responsible for the trait is present.

Recessive Traits

Genetic characteristics that are expressed in offspring only when two copies of the gene are present, one from each parent.

Dosage Compensation

A mechanism that ensures equal expression of genes from the sex chromosomes despite the difference in chromosome number between males and females.

X-Linked Gene

A gene located on the X chromosome, with its expression and associated traits often differentially presented in males and females due to X-chromosome inactivation or hemizygosity in males.
