A mutant red coat color allele (Yr) arises in island B and is present in the adult population in a heterozygous individual in the population of 117 adults of year 2000. Yr is recessive to the other alleles at the Y locus. What is the probability (p) that, purely by the action of genetic drift, the allele will rise to fixation (reaching a frequency of 1.0) at some time in the future? (A) 0.0 < p < 0.2 (B) 0.2 < p < 0.4 (C) 0.4 < p < 0.6
(D) 0.6 < p < 0.8 (E) 0.8 < p < 1.0

For the same genetic scenario, what if the single red allele arose in the island A and was present by 1990 in a heterozygous individual, one of a population 12 individuals. Would this red mutant allele have a better or worse chance of rising to fixation relative to the island B population of problem 5?
(A) red allele more likely to reach fixation in A island beginning in 1990 compared to B island beginning in 2000.
(B) red allele less likely to reach fixation in A island beginning in 1990 compared to B island beginning in 2000.

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. b. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. c. prokaryotic poly-a tails have other functions, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.
