Try drawing one for yourself. lowercase B, capital T lowercase t. And I'm just going to go through two hybrids, this is called a monohybrid cross Each gamete is haploid for the A gene, meaning it only contains one copy of that gene. This is also an autosomal dominant genetic disorder. However, some traits are not inherited with the simple mathematical probability suggested here. The Punnett square shows the inheritance of pea pod color. You could get the B from your they will assort independently.
