In a pedigree,a circle represents a female. A square represents a male.Half-shaded circle or square indicates that a person is a carrier of the trait. A completely shaded circle or square indicates that a person expresses the trait.
The correct answer in this question is option A. Biochemical analysis uses similarities in DNA sequences as evidence for evolutionary relationships. Scientists believed that two species with almost the same protein structure are more likely to have a closer relationship. DNA hybridization and gene sequencing are two types of analysis that can be used.
The nucleus will have the greatest mass. Among the 3 kinds of subatomic particles, electrons are the lightest (by several orders of magnitude), protons and neutrons are much closer is magnitude, though neutrons are slightly heavier. However, in the diagram, the nucleus contains both the neutrons and the protons, so its combined mass would be heavier than either the neutrons alone or the protons alone.
