What is an recessive trait?
An X-linked recessive trait is coded for by a gene on the X-chromosome and is not dominant (is canceled out by the presence of a different allele). Example of X-linked recessive traits are; Haemophilia A & B and Duchenne muscular dystrophy.
Which type of muscular dystrophy is X-linked?
Duchenne
What is an X linked traits?
An X-linked recessive trait is coded for by a gene on the X-chromosome and is not dominant (is canceled out by the presence of a different allele). Example of X-linked recessive traits are; Haemophilia A & B and Duchenne muscular dystrophy.
Is duchenne muscular syndrome dominant or recessive?
It is a recessive X linked form of muscular dystrophy
What makes something a sex linked trait instead of just a regular trait?
A sex linked trait can only be found on the x chromosome such as hemophilia, color blindness, and muscular dystrophy. These are traits that can only be inherited through chromosomes instead of regular traits coming through genes.

What type of birth disporder is Duchenne muscular dystrophy?
Some disorders are linked to the sex-determining chromosomes passed along by parents.Duchenne muscular dystrophy, which causes muscle weakness.carried on the X chromosome
What disease most often occurs in males and causes muscular weakness and hypertrophy?
Certain forms of muscular dystrophy are x-linked, cause weakness, and can cause muscular hypertrophy as muscle cells are replaced with fat.
What are three diseases that are sex linked like hemoplilia?
Three disorders which are sex-linked are: Fragile X syndrome Duchenne muscular dystrophy Colour blindness (most forms, but not all)
What race does Duchenne Muscular Dystrophy usually occur in?
Duchenne Muscular Dystrophy is more commonly seen in males of all ethnicities. It is an X-linked recessive disorder that primarily affects males because the gene mutation responsible for the condition is located on the X chromosome.
Can girl have muscular dystrophy?
The short answer is yes, absolutely. You may be primarily thinking of sex-linked dystrophies, such as Duchenne's or Becker's Muscular Dystrophy. The gene mutations for these types of dystrophy are recessive traits located on the X chromosome. It is vastly more common in boys then in girls because boys only have one X chromosome. If they get the gene for these dystrophies on their mom's X chromosome, then they will not have another X chromosome to "mask" the trait, and thus they will get the disease. Since girls have two X chromosomes, this is a lot rarer. Even if one X chromosome has the gene for the disease, as long as the other one doesn't, they are only a carrier, they don't actually have symptoms. There are only two ways where a girl can get a sex-linked dystrophy: if her mom is a carrier and her dad has the disease, or if her X chromosomes mutate in a way that make her have the gene on both X chromosomes. However: Muscular dystrophies come in dozens of types. Sex linked varieties may be among the most common, but there are plenty out there that are autosomal (i.e.: not sex-linked). Some come from autosomal recessive genes, other come from spontaneous mutations. For those types of muscular dystrophy, girls are just as likely to get them as boys.
Is an x linked dominant trait the same as an x linked recessive gene?
An X-linked recessive trait is coded for by a gene on the X-chromosome and is not dominant (is canceled out by the presence of a different allele). Example of X-linked recessive traits are; Haemophilia A & B and Duchenne muscular dystrophy.
