Whether or not a trait is common has to do with how many copies of that gene version (or allele) are in the population. It has little or nothing to do with whether the trait is dominant or recessive.

Is curly hair a dominant or recessive trait?

What are the 3 laws of inheritance?

The key principles of Mendelian inheritance are summed up by Mendel's three laws: the Law of Independent Assortment, Law of Dominance, and Law of Segregation.

What is the P generation?

The parental generation refers to the first set of parents crossed. The parents' genotype would be used as the basis for predicting the genotype of their offspring, which in turn, may be crossed (filial generation). ... These two plants comprise the parental generation (P generation).
