Duchenne muscular dystrophy (DMD) is a recessive X-linked disorder, which results in symptoms before the age of 6. A young girl, diagnosed with DMD has a 46 XX karyotype. The young girl’s brother is also living with DMD. Curiously, both parents are normal.
-
- Given the information in the question, why does this young girl have DMD? (1 sentence)
-
- How does this young girl have DMD? What mechanisms and how did this mechanism lead to this girl exhibiting DMD? (1 or 2 sentences)
Homework Answers
A) 46XX chromosome mutation causes Duchenne muscular dystrophy.Due to this condition the girl have DMD.
B) When a person X chromosome have a gene mutation in DMD gene then they will have DMD even if both parents are normal.

Duchenne muscular dystrophy (DMD) is a disease that results in progressive muscle weakness, ultimately leading to paralysis. DMD is a genetic disease that is inherited in an X-linked recessive fashion. Two parents have a large number of children, and find that some of their children have DMD. Specifically, they find that none of their daughters have DMD, but half of their sons have DMD. a. What is the genotype the two parents? Please be sure to specify which genotype corresponds...

Duchenne muscular dystrophy is an X-linked recessive condition affecting humans. It is a major form of muscular dystrophy. A female is a carrier (unaffected) and she has children with an unaffected man, and they have a boy. What is the percent probability that the boy will have the Duchenne muscular dystrophy disease? Enter your answer as a percentage value rounded to the nearest whole number. Do not enter a % sign. (i.e. enter 75, not 0.75 or 3/4)

A couple (both of which are normal) has a son that has Duchenne muscular dystrophy. This is a rare sex-linked recessive disorder which causes muscle deterioration that almost always affects boys. The parents believe that the hospital mixed their child up with a normal child and sue the hospital. You have once again been called as an expert in genetics to testify. What do you tell the jury? Is it possible that these are the biological parents or did the...
