The autosomal chromosomes are the non sex chromosomes. The sex chromosomes determine the sex of an individual. In humans we have 23 pairs of chromosomes in total. This is made up of 22 pairs of autosomal chromosomes and one pair of sex chromosomes. The autosomal pairs are all recognisable by specific shapes and are numbered The pairs are identical in size, shape, the genes that they carry, but not always the same form of the gene.

Sex-linked dominant

Understanding Autosomal and Sex-Linked Inheritance - AP Biology

Sex-linked dominant is a rare way that a trait or disorder can be passed down through families. One abnormal gene on the X chromosome can cause a sex-linked dominant disease. Inheritance of a specific disease, condition, or trait depends on the type of chromosome that is affected. It can be either an autosomal chromosome or a sex chromosome. It also depends on whether the trait is dominant or recessive. Sex-linked diseases are inherited through one of the sex chromosomes, which are the X and Y chromosomes.

8.4: Mendelian Inheritance

Pedigrees are genetic diagrams that track the inheritance of a trait through generations. Generally, on a pedigree, biological males are depicted as squares and females are depicted as circles. A shaded in shape represents the expression of a given trait. Sex-linked pedigrees are different from autosomal pedigrees because sex-linked pedigrees show the inheritance of sex-linked traits which tend to
Some genetic conditions are caused by mutations in a single gene. These conditions are usually inherited in one of several patterns, depending on the gene involved:. Many health conditions are caused by the combined effects of multiple genes described as polygenic or by interactions between genes and the environment. Such disorders usually do not follow the patterns of inheritance listed above. For more information, please see What are complex or multifactorial disorders?
