1. 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

2. Multiple Genes RrSs = rrSs = RRss = Rrss = RrSS = RRSS = Red Light Red
Very Dark Red
Dark Red

3. Multiple Genes
Cross medium wheat (RrSs) with dark red wheat (RrSS).
