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

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

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