Question 1 Not yet graded / 0 pts
We are taking this quiz under unusual (awful) circumstances. We're all in this
together. It is important that this exam is fair to all students, and that no student has
an unfair advantage.
With that in mind, please affirm the following:

Osuare Atafo
Question 2 pts
Forest tree species typically show high measures of within-population genetic
diversity (e.g., heterozygosity) and low levels of among-population genetic diversity
(e.g., FST).
Which of the following life-history traits might influence these two factors?
Large and continuous geographic ranges
Wind seed dispersal mechanisms
Animal seed dispersal mechanisms
Wind pollination mechanisms
Question 3 pts
Why was the mutation of the sickle cell allele (HbS) not eliminated from the human
'gene pool'?
HbS - sickle cell
HbA - non-sickle cell

Because when an individual has the homozygote genotype (HbS/HbS) it is fatal.
Because when an individual has the homozygote genotype (HbA/HbA) it means that
the person has protection against malaria.
Because when an individual has the homozygote genotype (HbA/HbA) there is no
advantage conferred to the individual.
Because when an individual has the heterozygote genotype (HbA/HbS) it confers no
advantage to the individual.
Because when an individual has the heterozygote genotype (HbA/HbS) it confers
resistance to malaria.
Question 4 pts
Which statements are true regarding genetic variation from an evolutionary
standpoint?
It is an important factor of evolution as it allows natural selection to increase or
decrease frequency of alleles in a population.
If all individuals of a population were genetically homogenous, the entire population
could be vulnerable to new biotic disturbances.
It permits flexibility and survival of a population in the face of changing environmental
circumstances
