Question

Only answer question c please

6. After a population becomes divided by some barrier to gene flow (i.e., reproductive isolating barrier), alleles
in the two resulting populations go through a process called lineage sorting. This process is illustrated in the
diagram below, in which the past is at the top and the present at the bottom.
a) What type of relationship do the two populations have
immediately after time X: Polyphyletic, paraphyletic, or
reciprocally monophyletic? Briefly explain how you
know this.

1.) Consider flower color in a hypothetical population of 7,000 flowers, red flowers (4,000), blueflowers (2,000) are dominant over pink flowers. If there are 1,000 pink flowers, find thefollowing:a. Frequency of dominant (red flower) alleleb. Frequency of recessive (pink flower) allelec. Frequency of each genotype (homozygous dominant, homozygous recessive,heterozygous)d. Make a Punnett square and use the rule of multiplication.
3. a. Why are most populations not in Hardy Weinberg Equilibrium? b. There is an ancient village population of humans. We know very little about this population. How can we use genetics to determine if the societal system of the village was matrilocal or patrilocal? c. There was variation in a rat phenotype (coat color.) The coat colors ranged from dark color coats to light color coats. As the rats migrated into the basements of campus, the light color rats were more likely to be caught by the campus cat. Over time, the basement rat population shifted to entirely dark color coats. This is an example of what kind of selection? d. Explain how a genetic bottleneck could lead to higher susceptibility of a disease, such cancer, in that population.
1A) When you have extreme inbreeding (i.e. same genotypes mate to give rise to the next generation), the percent of heterozygotes will decrease by ________ % a generation, whereas the percent of AA homozygotes will increase ________ % each generation and the percent of aa homozygotes will increase ________ % each generation . 60, 40, 0 none 50, 25, 25 50, 10, 40 25, 50, 25 1B) What is the one measurement we have to make if we want to know the percentage of particular genotypes within an actual population, assuming complete dominance and two alleles? the frequency of dominant phenotypes the frequency of heterozygous genotypes the frequency of recessive phenotypes all of the options are correct the frequency of heterozygous phenotypes
1.A small group of turtles float on a log to an island and establish a new population there. How do you expect the genetic diversity of the island turtles to compare to genetic diversity of the mainland turtle population they originated from? Group of answer choices A. Genetic diversity should be similar, since they are the same species. B. Genetic diversity should be higher for the island turtles, because the new environment will produce new alleles. C. Genetic diversity should be lower for the island turtles, since the island turtles represent a small sample of the genetic diversity from the mainland turtles. 2.If the probability of a turtle having a brown shell is 3/4 and the probability of a turtle having a bumpy shell is 1/4, what is the probability of a turtle that has a shell that is both brown andbumpy?

5) 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 < 1.05 6) 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…
