What is sex linked trait

Sex-linked traits are characteristics other than sex that are carried by the sex chromosomes coiled structures in a cell's nucleus that carries the cell's genetic information. Sex chromosomes in humans do more than determine whether a person is male or female, and they can carry such traits as the condition color blindness and the disease muscular dystrophy. Most sex-linked traits occur only on the X chromosome since it is larger than the Y chromosome. At fertilization the union of sperm and egg , the new embryo that is created receives half twenty-three its chromosomes from the female parent and half twenty-three from the male parent.

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. In females, the effect of the mutation may be masked by the second healthy copy of the X chromosome. Sex linked These are traits that are found on either one of the chromosomes that determine sex, or the sex chromosomes.

Definition noun, plural: sex-linked traits A trait genetically determined by an allele located on the sex chromosome Supplement A sex-linked trait is a trait that is controlled by a gene or an allele located on the sex chromosome. In humans, the sex chromosomes are the X chromosome and the Y chromosome. A trait that is determined by the allele on X chromosome is particularly described as X-linked whereas that determined by the allele on Y chromosome is said to be Y-linked.

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.
