Chapter 10, Problem 8GP
Summary Introduction
To determine:
The proportion of male offspring that will walk backwards.
Concept introduction:
The genes causing X linked disorders are present on the X chromosomes. The X linked disorder can be dominant or recessive. Silly, a male fraggle had an X-linked recessive disorder that made him walk in backward direction. He mated with a female Lilly who was a carrier for fraggle.

Thus, a female who is heterozygous for this gene and does not have the disease can be a carrier. What kind of offspring can you expect from a DMD-affected male and a carrier female? Can there be a carrier male?arrow_forward
