... 4. Each time we add a gene it doubles what we had. So 2 genes were 2 x 2 = 22 = 4, 3 genes is 4 x 2 = 23 = 8 and so on until we get to 22 genes. That’s 222= 4, 194,304 unique combinations. That’s just possible sperm or eggs. Combine those and you get a possible 17 trillion unique children from one c ...
