This means that each dominant allele "adds" to the expression of the next dominant allele. Usually, traits are polygenic when there is wide variation in the trait. For example, humans can be many different sizes. Height is a polygenic trait, controlled by at least three genes with six alleles.

G always pairs with C...So, if there is 30% G, then there's 30% C...which is 60%...that leaves 40% A+T - and you have to split this up too - so 20% Thymine (T) and 20% Adenine (A).
A eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have a membrane-bound nucleus.
