Answer:
The correct answers are
Question a) "50%".
Question b) "66%".
Explanation:
Achondroplasia is caused by a dominant allele, which means that a person with a "A" allele will develop this condition. In this case, all the people with Achondroplasia are heterozygotes "Aa" because the dominant genotype "AA" causes prenatal death. If a person with achondroplasia "Aa" mates with a person of average height "aa", the expected percentage of children with average height will be 50%, since there are 50% of chances of having "aa" children and 50% chances of having "Aa" children. Also, If two persons with achondroplasia have children ("Aa" x "Aa") , the expected percentage of children with achondroplasia will be 66%. The probability of having children with the "Aa" genotype is 50%, however since the "AA" genotype causes prenatal death, this genotype is not considered in the percentage.
