Human genetic disease - Sex-Linked Inheritance: In humans, there are hundreds of genes located on the X chromosome that have no counterpart on the Y chromosome. Each person inherits one sex chromosome from each parent, resulting in either an XX configuration for females or an XY When a female parent is homozygous for a recessive X-linked trait, she will pass the trait on to 100 percent of her male offspring, because the males will receive the Y chromosome from the male parent. If a carrier female has children with a normal male, what is the probability that a child with hemophilia will appear in the offspring? Explain your answer. These genes provide instructions for making clotting factor (coagulation factor) proteins that form blood clots. The shorter Y chromosome does not carry the allele for the sex-linked trait. It predominantly affects males, as they possess only one X chromosome, while females have two and therefore require both to be affected. Sex-linked traits are fascinating because they reveal how genetics can influence characteristics based on one's sex.

A man with hemophilia (a recessive, sex-linked blood clotting disorder) has a daughter of normal phenotype. Explains how haemophilia is sex-linked and that some female carriers may not have symptoms while other females might have haemophilia. Females typically need two mutated X chromosomes to express hemophilia but carrying one mutated X chromosome makes them carriers. Males will either have the disease or not (but they won’t ever be carriers) = female, normal = female, carrier = female, hemophiliac When a female parent is homozygous for a recessive X-linked trait, she will pass the trait on to 100 percent of her male offspring, because the males will receive the Y chromosome from the male parent.
