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.

WHO | Gender and Genetics

When a genetic disorder is diagnosed in a family, family members often want to know the likelihood that they or their children will develop the condition. This can be difficult to predict in some cases because many factors influence a person's chances of developing a genetic condition. One important factor is how the condition is inherited. For example:. Autosomal dominant inheritance: A person affected by an autosomal dominant disorder has a 50 percent chance of passing the mutated gene to each child. The chance that a child will not inherit the mutated gene is also 50 percent.

How Hereditary Illnesses Work

The following will give you information about what X linked inheritance means and how X linked conditions are inherited. To understand X linked inheritance, it is first helpful to know about genes and chromosomes. Our bodies are made up of millions of cells. Most cells contain a complete set of genes.

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.
