Question

2. Explain how you determined the genotype of Maria and Juanita, even though you did not test their DNA.

Answer 1

You can determine the genotype of Maria and Juanita, even though you did not test their DNA is by looking at the traits of their parents. If they have other siblings, the ratio of the traits can give the actual genotype of their parents which in turn, can help determine the genotype of Maria and Juanita. This is assuming that the genotype in question corresponds to an observable physical trait.
