Multiple Genes

Much like dihybrid, but more capital letter
alleles contribute to more of the specific
trait

Ex.
Four dominant genes produce very dark red kernels.
Three dominant genes produce dark red kernels.
Two dominant genes produce red kernels.
One dominant gene produces light red kernels.
A lack of any dominant genes would be albino
