Color in these beetles is determined by different versions of a gene—different alleles.

Green is the dominant trait so green beetles have two green alleles or a green allele and a brown allele.

Brown beetles have two brown alleles.

By counting the brown alleles and green alleles we can calculate that this population has 30% brown alleles and 70% green alleles.
