Chromosomes and Phenotyperename

SummaryThe chromosomes on which genes are located can affect the expression of traits. Two alleles of autosomal genes interact to produce phenotype. Genes on the
sex chromosomes are expresses differently in male and females of many species. In humans, males are XY and females are XX. Males only have one copy of
each gene found on the sex chromosomes, so all of those genes are expresses in their phenotype.
|Carrier||doesn't show disease symptoms, but can pass disease-causing alleles to offspring|
|Sex-linked genes||genes located on sex chromosomes|
|X chromosome inactivation||one of the 2 x chromosomes is turned off and is not expressed|
