Dimples are dominant over no dimples. A mother that does not have dimples marries a man. Together they have 4 children. 2 of them have dimples and 2 of them do not. Determine the genotype and phenotype of the FATHER and explain your choice .Include the possible genotypes of offsprings.

Alex is newly pregnant with twins and curious about everything about her developing children. Her doctor was able to tell her that her twins are dizygotic twins via ultrasound. In your essay, describe the difference between monozygotic and dizygotic twins and explain how each is conceived. Alex is also wondering about the genetics of her children and how they will act when they are older. Offer an explanation of genotype and phenotype and provide an example of each specific to Alex’s future children being dizygotic twins. Finally, in your previous explanation be sure to also describe how most traits are both polygenic and multifactorial and how that may influence her twins’ phenotypes.
