<span>Amylase needs an optimum pH for its activity. It is in the range of 6-7. Below or above pH will denature this enzyme. The pH level is optimum for this enzyme in the mouth and hence it catalyses the break down of sugar. The pH level of stomach is lower than its optimum level duet to the activity of gastric acid. Hence the enzyme becomes inactive in the stomach.</span>

Answer:
The correct answer is 6 genotypes
Explanation:
The most known case is two alleles of one gene (A and a), and we know the possible genotypes formed are three: AA, Aa, aa. Therefore, for a given number of alleles n, we calculate the number of possible genotypes as the sum of integers between 1 and n.
- For 2 alleles (n=2, the sum of integers between 1 and 2): Genotypes= 1 + 2= 3
⇒ For 3 alleles (n=3, the sum of integers between 1 and 3): Genotypes= 1 + 2 + 3= 6
So, we have 6 genotypes for 3 alleles (W1, W2 and W3) and they are:
W1W1
W1W2
W1W3
W2W2
W2W3
W3W3
