The statement we could make about the four species based on the phylogenetic or evolutionary tree would be that they all originate from one gene pool or source. As evolution expands, one animal or species develops many different accommodations to their geneology based on environmental factors. Over a span of thousands of years, these changes can lead to an entirely new species.

Answer:
Lisa and Monica
Explanation:
<em>The correct answer would be Lisa and Monica.</em>
<u>For X-linked recessive disorders, a female can be unaffected, a carrier, or affected. However, a male can either be affected or unaffected and never a carrier. This is because females have two X chromosomes while males have only one.</u>
In addition, completely filled-in shapes in a pedigree mean that such individuals are affected for the trait in question while half-filled shapes mean the individuals are carriers for the trait.
Hence, individuals in the pedigree that are labeled carriers for red-green color blindness are Lisa and Monica (they both have half-filled shapes).
