Cartina’s eyes are brown, just like her mother’s eyes. Cartina has long fingers like her father, but her mother’s fingers are much shorter. What is the most likely reason why Cartina’s appearance is similar to and different from that of her parents?

What evidence in pea plant crosses supported Mendel’s Law of Independent Assortment?
There is a pair of identical twins in Ajani’s class. One of them was affected by a severe illness during his first few months of life. Although he survived, he is much shorter than his twin brother. How is this difference explained?

A particular species of moth can have green or yellow scales on its wings. The scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. When moths that are homozgyous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales. Based on this information, how do the alleles for scale color interact?
