It also depends on whether the trait is dominant or recessive. The dominant allele is often given the capital letter while the recessive allele is given the lower case. 2D Animation of Genes and Inheritance. The dihybrid cross Punnett square calculator allows you to calculate the chances that 2 traits will be inherited at once. Autosomal recessive: A genetic condition that appears only in individuals who have received two copies of an autosomal gene, one copy from each parent.
