Answer:
p=0.9
Explanation:
The frequency of the different genotypes is as follows:
- AA = 0.81
- Aa = 0.18
- aa = 0.01
There are 2 alleles for this gene, the dominant allele <em>A</em> appears twice in the homozygous dominant genotype and once in the heterozygous.
Then, the frequency of the <em>A </em>allele, <em>p</em>, can be calculated as:
p= freq(AA) + freq(Aa)/2
p= 0.81 + 0.18/2
p=0.9
Generally speaking, if a person had an overall amylase deficiency (alpha, beta, and gamma), they would naturally have hypoglycemia or low blood sugar. They would have to regularly take supplements in order to compensate for said amylase deficiency. This may put a strain on their pancreas, since their levels of insulin (decreases blood sugar) and glucagon (increases blood sugar) would become abnormal, and would increase the demand for insulin.
