I have model with 20 genes which can take on a value of 1 or 0 (the alleles). What is their expected value and variance assuming the alleles are selected with equal probability?
Is this just a binomial distribution?

Yes, assuming independence and equal probabilities, this is just the binomial distribution. So the number of alleles of value 1 is $X\sim \mathcal{Binom}(20,p)$.
