Females have 2 X chromosomes so the X-linked genes follow the same rules of dominance & recessivity as the genes on the autosomes.
Sex-linked inheritance involves traits that are linked to genes on the sex chromosomes (X and Y). Traits carried on the X chromosome are typically expressed differently in males and females due to differences in the number of X chromosomes they inherit. Examples include color blindness and hemophilia.
Sex-linked inheritance refers to the inheritance of traits that are carried on the sex chromosomes (X and Y). Maternal inheritance, on the other hand, refers to the inheritance of traits that are passed down exclusively from the mother through the mitochondrial DNA. Sex-linked traits can be passed down by both males and females, while maternal inheritance is specific to traits passed from the mother.
One key difference is that autosomal traits are located on the autosomes (non-sex chromosomes), while sex-linked traits are located on the sex chromosomes (X or Y). This difference affects how these traits are inherited and expressed, as sex-linked traits show different inheritance patterns among males and females.
The inheritance of sex-linked traits through meiosis is where chromosomes are replicated. This relates to genetics in that the traits are passed on to divided cells from the parent cell.

Sex-linked traits in humans follow specific inheritance patterns based on the genes located on the sex chromosomes. In males, who have one X and one Y chromosome, sex-linked traits are typically passed down from the mother on the X chromosome. In females, who have two X chromosomes, the trait can be passed down from either parent. This results in different patterns of inheritance for males and females when it comes to sex-linked traits.
Sex-related inheritance can be categorized into two main types: sex-linked inheritance and sex-influenced inheritance. Sex-linked inheritance involves genes located on the sex chromosomes, primarily the X chromosome, where traits can manifest differently in males and females due to their differing sex chromosome compositions. In contrast, sex-influenced inheritance refers to traits that are expressed differently based on the sex of the individual, even though the genes are located on autosomes, such as the influence of hormones on the expression of certain traits.
Inheritance of sex-linked traits differs between boys and girls because boys have one X and one Y chromosome, while girls have two X chromosomes. This means that boys inherit sex-linked traits from their mothers, while girls can inherit them from both parents.
A trait controlled by a gene on the sex chromosome is known as a sex-linked trait. These traits are often inherited in a sex-specific manner, with different patterns of inheritance depending on whether the gene is located on the X or Y chromosome.
Two sex-linked traits present in humans are color blindness and hemophilia. These traits are carried on the X chromosome and are more commonly expressed in males due to their inheritance pattern.
Sex-linked mutations and gene mutations are alike in that both involve changes to the DNA sequence that can affect an organism's traits or functions. However, they differ in their location and inheritance patterns: sex-linked mutations occur on the sex chromosomes (X or Y), typically affecting traits associated with gender, while gene mutations can occur on any chromosome and affect a wide range of traits regardless of sex. Additionally, sex-linked mutations are often passed down differently in males and females due to their association with sex chromosomes.
These are called sex linked genes since they are on the genes that code for sex.
