The cells in the body don’t work correctly when a protein is altered or produced in not enough quantity, or sometimes not produced at all. Sometimes muscular dystrophies are caused by spontaneous mutations that can’t be found in their parents, the defect can be passed down to the next generation. There are three way muscular dystrophies can be inherited. One way being autosomal dominant inheritance which happens when the child receives one normal gene from a parent and one defective gene from another parent, only one parent is needed to pass along the abnormal gene in order to produce the disorder. When one parent has the abnormal gene there is a 50% chance that either gender can be at risk, depending on the person the disease is more or less severe. Another way is autosomal recessive inheritance which occurs when both parents have to carry and pass on the gene. Which means both of the parents have one defective gene but are not affected by it. Kids have a 25% chance of inheriting both copies of the defective gene and a 50% chance of inheriting one gene, which makes them a carrier, meaning they can pass it down to their children. The third way is x-linked recessive inheritance which means the mom has the affected gene on one of the two X chromosomes and passes
