Latin I think. It's like nomenclature, or something like that. ☺
What are the answer choices ?
Scientists compare the anatomy, embryos, and DNA of living things to understand how they evolved. Evidence for evolution is provided by homologous structures. These are structures shared by related organisms that were inherited from a common ancestor.
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.
