Genotype refers to the complete genetic make-up and can also be referred to as the alleles an organism carries on a particular gene.
John's genotype with unattached being dominant is Aa.
- Using A to represent the alleles
- Since his mother has attached earlobes, her condition can only be inherited in the recessive condition (aa).
