1) I have mostly dominant traits.

2)The dominant trait is not always common in a population, this is because the population constituent is dependent on the starting population, and not on the dominant or recessive nature of the allele. Traits can be of course become more common over time, but that doesn't mean that traits are influenced by dominance or recessiveness of the allele.

If we consider my data set, we see that the dominant traits are not so common at times, while it is very common at times and vice versa. This suggests that being dominant allele does not mean that it should be the more common trait.
