John had unattached earlobes like his father, but his mother has attached earlobes. What is johns genotype with unattached being dominant

Respuesta :

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).
  • So for John to have an unattached earlobe, his father has to be either AA or Aa.
  • Therefore John's genotype would be Aa
