Question

12. A trait is coded by a single locus with three alleles. The allele frequencies are: Ai 0.2; A2 0.3; A 0.5. If the population is at Hardy Weinberg equilibrium which is the correct order of relative abundance in the population? a. More A3As than A2A3 b. More A1Ai than A2A2 c. More AiA3 than A3A3 d. More A2As than A3A3 ree inferences led Darwin to propose the theory of evolution by natural 13. Th selection. Which of the following is NOT one of those inferences? a. Mutation leads to variability upon which selection can act. b Organisms have the capacity to reproduce in excess of replacement, leading to a struggle for existence. c. Superior competitors win in this struggle for existence. d. Heritable traits that enhance an individual's chance of survival will increase in frequency through time

Explanation / Answer

12) C

13 ) A

Because the three interferences are

1) production of more individuals than that the nature can support leads to a struggle for existence among the individuals of a population with only a fraction of the offspring surviving each generation

2) differential reproduvtive success in which an organism with trait favored by environment produce more offspring than do organism without those traits leading in the favored trait being disproportionately represented in the next generation it has nothing to do with the sizr or strength.

3) This unique abilities of individuals to survive and reproduce will lead to a gradual change in a population with favorable characteristics accumulating over generations.
