Answer:
Gametes that will be produced are:
YST, YSt, YsT, Yst, yST, ySt, ysT, yst
Explanation:
From YySsTt, it is obvious that as there 3 type of genes.
The number of gametes = 
= 8
5 genes = 
= 32 genotypes
10 genes = 
= 1024 genotypes
20 genes = 
= 1048576 genotypes
Starting at least level up to the largest as organized by ecologists, see the chart below.
