Each individual has a pair of sex chromosomes ; one member of the pair is inherited from each parent. In humans, for example, the X , or female-determining, chromosome carries many genes, whereas the Y , or male-determining, chromosome is deficient in genes. A woman has two X chromosomes; a man has one X chromosome and one Y chromosome. Several traits, including red-green colour blindness , arise from the interaction of genes that are located on the X chromosome. A man a Y carrier has no opposite-acting genes on the Y chromosome that could influence or suppress the action of the genes on the X chromosome. Hemophilia is another trait controlled by genes located on the X chromosome and is thus transmitted to males only through the female line.

Sex-Linked Traits and Disorders

Sex linked is a trait in which a gene is located on a sex chromosome. In humans, the term generally refers to traits that are influenced by genes on the X chromosome. This is because the X chromosome is large and contains many more genes than the smaller Y chromosome. In a sex-linked disease, it is usually males who are affected because they have a single copy of X chromosome that carries the mutation.

Sex-linked traits

Sex chromosomes are found within our reproductive cells and determine the sex of an individual. Traits are passed on from one generation to the next by our genes. One allele for a trait is inherited from each parent. Organisms that reproduce sexually do so via the production of sex cells , also called gametes.

Sex linkage refers to when a gene controlling a characteristic is located on a sex chromosome X or Y. X and Y chromosomes. As human females have two X chromosomes and therefore two alleles , they can be either homozygous or heterozygous.
