How can evolution of a population occur without changing the allele frequency of a trait within the population?

When heritability is 0%, genes play:

Why can’t we measure genetic variation in a population using observable traits (phenotypes)?

When heritability is 0%, genes play:

You are examining a human pedigree for a trait. You notice that an offspring can be affected even if neither parent is affected. This immediately tells you that the trait is:

Which of the options correctly lists the stages of human development in order?

Mendel crossed true-breeding yellow-seed plants with true-breeding green-seed plants. Given that yellow color is a dominant trait, what would the genotype of the offspring be?
