Scientific knowledge and reasoning can provide an empirically-based perspective to inform society's decision making. For example, a genetic counselor may discuss with parents the probability of them having a child with a genetic disease caused by a recessive allele. The counselor may use a Punnett square to illustrate the chances of having such a child. What is this genetic counselor using when constructing the Punnett square to advise these parents?
A) how certain traits are determined by more than one gene
B) how mutations can affect the genetic information
C) Mendel's law of segregation
D) Mendel's law of independent assortment
Ans: C) Mendel's law of segregation

The Janzen-Connell hypothesis:
A. proposes that interactions with hostspecific pathogens, herbivores or seed predators play a role in decreasing plant diversity. B. was based on the observation that seeds often suffer lower rates of herbivory when growing directly beneath a parent tree. C. was supported by research that demonstrated that seeds that disperse far from their parent tree will escape from seed predators. D. was supported by data that indicated that seed and seedling mortality was not density dependent, thus favoring more common species. E. indicates that rare plants do not survive well in the tropics.
