a. determine the frequency of stains in the current season

b. utilizing the most virulent strain from the current season

c. completing gain-of-function experiments with flu strains in the lab

d. identify the most novel and divergent strain in the antigenic regions of the hemagglutinin protein

2. Which of these describes antagonstic pleiotropy?

a. genes that increase reproduction may decrease survival later in life

b. mating only once in life, then dying

c. steep reduction in fertility and fecundity late in life

d. the later in life that a mutation affects fitness, the weaker the selection against that mutation
