Briefly explain what is sex linked characters as used in genetics?

Sex-linked characters are traits that are determined by genes located on the sex chromosomes, specifically the X and Y chromosomes. These traits are often inherited in a sex-specific manner, with males and females showing different patterns of inheritance. For example, traits that are located on the X chromosome are typically passed from mothers to sons, as sons inherit their X chromosome from their mother. This can result in certain traits being more common in one sex than the other.

Sex-linked characters are genetic traits that are carried on the sex chromosomes. In humans, females have two X chromosomes, while males have one X chromosome and one Y chromosome. This means that males are hemizygous for sex-linked genes, while females are heterozygous.

Sex-linked genes can be dominant or recessive. If a sex-linked gene is dominant, then males will be affected by the trait if they have one copy of the dominant allele. Females will only be affected by the trait if they have two copies of the dominant allele. If a sex-linked gene is recessive, then males will be affected by the trait if they have one copy of the recessive allele. Females will only be affected by the trait if they have two copies of the recessive allele.

Examples of sex-linked traits include colorblindness, hemophilia, and muscular dystrophy.
