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
