Question 92 (2 points)
There are many genetically inherited diseases or conditions. When the allele, causing the condition, is recessive the
parents can be carriers of the allele but they are unaffected by the disease themselves. The dominant allele protects
them. However, there are conditions caused by dominant alleles. For example, the condition Achondroplasia,
which causes dwarfism in humans, is the result of a dominant allele. Therefore only one allele is required to have
Achondroplasia. Achondroplasia is lethal for those that are homozygous dominant and no adult exists with that
genotype. Migraine headaches are another example of a dominant allele causing a deleterious condition. In cases
like this at least one parent is affected by the condition if it is passed to the offspring. We will use A and a to
represent the dominant and recessive alleles for Achondroplasia. In addition, M and m will be used for the dominant
and recessive alleles for migraine headaches. Consider the following problem. A woman with Achondroplasia who
has never had a migraine headache marries a man that has migraine headaches but does not have Achondroplasia.
