Fiure A Figure C From: "Why our flu vaccines can't keep up" Which one of the graphs shows the frequency of trait variation in the surviving sparrow population after the storm.?

> Within a certain population, there are exactly 2 alleles at the T locus: T and t. Among the entire population, 30% of the alleles are T. If this population is in Hardy Weinberg equilibrium, what proportions (or percentages, however, you want to express it) will be TT, Tt, and tt? Show work. In a population, there are 75 TT individuals, 25 Tt individuals, and 250 tt individuals. What are the frequencies of T and t? Show work. What are the "expected" numbers of each genotype? Show work. Ís this population in Hardy Weinberg equilibrium? (don't do Chi², just compare your answer in a) b) c) part b io actual and it should be obvious.) ) Assume that, in a population of deer, two alleles exist for eye color. BB deer have blue eyes, Bb deer have purple eyes, and bb deer have red eyes. Out of a population of 1000 deer, 490 have blue eyes. You took notes on the amount of red and purple eyed deer, but your notebook fell in the mud and those numbers are obscured. However, if the population is in…

Using scenario 1 describe wheter the B allele frequency, and R allele frequency will increase, decrease, increase and decrease or remain the same

In a population of mayflies, variation in the STRIPE gene causes different body coloration. SS individuals have skinny stripes, Ss individuals have wide stripes, and ss individuals are unassigned. You collect some mayflies and estimate that the frequency of the S allele is 0.85. You want to know whether the population is evolving, so you will return to the same site next summer and collect 1000 mayflies from the next generation. If the population is not evolving, how many of the 1000 mayflies collected next summer should have wide stripes. (round to the nearest whole number) A. 255 b.850 C. 723 D. 23

Imagine you were to collect data from simulation 2 (negative selective pressure on SS genotypes) over five generations. The frequency of the S allele over time is graphed below. The graph shows a rapid decrease in the sickle cell allele frequency in the first generation but a slower decrease in later generations. By the fifth generation, the allele is not completely eliminated from the population. Provide two plausible explanations for why the S allele persists after five generations.

The figure below shows data on the frequency of the A1 allele at a locus over time (i.e., generations) in 10 populations of flour beetles evolving independently of one another. The populations were all maintained in the lab under the same conditions.
