Answer:
Explanation:
If there are 5 genes, let us assume that they are in the alternative forms with 2 possible gets for each five... So we have
2 possible gametes for each five = 2 to the power of 5 = 32 gametes
Then genotypes = 3 to the power of 5 = 243
The same also for 10 genes
2 possible gametes for each 10 = 2 to the power of 10 = 1024 gametes
Then genotypes = 3 to the power of 10 = 59,049
The same also for 20 genes
2 possible gametes for each 20 = 2 to the power of 20= 1,048,576
Them genotypes = 3 to the power of 20 = 3,486,784,401
