Yes, Duchenne muscular dystrophy is a genetic disorder caused by mutations in the dystrophin gene. It is inherited in an X-linked recessive manner, meaning it primarily affects males and can be passed down from carrier females.
A trait is sex-linked dominant if it appears in every generation and affects both males and females. It is sex-linked recessive if it skips generations, more common in males, and passed from carrier females to affected males. Mendelian inheritance patterns can help determine if a trait is sex-linked dominant or sex-linked recessive.
Parents who carry a recessive disorder gene have a 25% chance of passing the disorder to their children. They may not necessarily suffer from the disorder themselves, as carriers typically do not show symptoms. However, they can still transmit the gene to their offspring, who may then inherit the disorder.
Haemophilia is a sex-linked recessive disorder - which means it can skip a generation, but only if it is carried in the female line.A female can be a carrier of haemophilia, but a male cannot. This is because males only have one X chromosome, so if they have a defective X they will have the disorder. If a father has haemophilia, all of his daughters will also have haemophilia.
A disorder can be either dominant or recessive, depending on the specific genetic inheritance pattern. Dominant disorders only require one copy of the mutated gene to be expressed, while recessive disorders require two copies.
