61. Which of the following violates the assumptions of the Hardy-Weinberg model? The population is infinitely large. Every individual survives and reproduces equally well. The population does not change in size because of an influx of migrants. Sexual selection exists within the population. There are no changes in the chromosomal structures of individuals in the population.
77)Each graph below shows the frequency of the A allele in six simulated populations (each line in a graph) over 500 generations. Each of the six simulations within a graph were done with the exact same settings of relative fitness among the genotypes and population size BUT these settings differed between the four graphs. Which graph shows a situation in which the effect of selection is the highest relative to the effect of drift? C D A B
Describe a situation in which a population would undergo the bottleneck effect and explain what impact that would have on the population’s gene pool.
32. What is a species? Group of answer choices a.Two populations that only interbreed very occasionally or rarely if at all. b.An interbreeding population. c.Two populations that never interbreed.
48. Coevolution can best be described as ________. A. reciprocal evolutionary change among interacting species B. an antagonistic relationship, where both participants have lower fitness C. a mutualistic relationship, where both participants benefit D. a change in allele frequency in a population over time E. adaptations to the physical environment
86 In a population of 466 individuals, a locus has two alleles: T and t. If 108 individuals have the tt genotype, and the locus is at Hardy-Weinberg equilibrium, what is the frequency of the TT genotype? Round your answer to the second decimal place.
1. A population consists of 300 individuals with the following genotypes: AA – 100 Aa – 75 aa – 50 a. What are the values of p and q? b. Is the population in Hardy-Weinberg equilibrium? Explain.
79)In very a large population, which of the following genotypic fitness values would result in the most rapid loss of the allele a? AA: 1.0, Aa: 0.8, aa: 0.8 AA: 1.0, Aa: 0.9, aa: 0.8 AA: 1.0, Aa: 1.0, aa: 0.8 AA: 1.0, Aa: 1.0, aa: 1.0
75. Under the conditions of the Hardy-Weinberg equilibrium, what term in the equilibrium equation represents the expected genotype frequency for homozygous recessive individuals? p2 2pq 2p+q p2+2pq+q2 q2
1) In smurfs, blue tails are dominant to red tails. You observe the following distribution in a smurf population: 214 blue tailed individuals genotype BB 37 blue tailed individuals genotype Bb 19 red tailed individuals genotype bb Is this population in HW equilibrium for the blue tail gene? Show your work. If the population is not in HW equilibrium, what might me causing the disequilibrium?
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.
1. In a population of plants, flower color is controlled by a single gene with two alleles (P and p). PP individuals have purple flowers, Pp individuals have pink flowers, and pp individuals have white flowers. Suppose you randomly sampled 100 individuals from the population and found that 75% of the plants had purple flowers, 20% had pink flowers, and 5% had white flowers. a. With regard to the flower color gene, is the population in Hardy-Weinberg equilibrium? Use the space below to show your work. Critical value df=1= 3.841 b. n a second population of the same kind of plants, 16% of the plants have white flowers. Assuming a) that flower color is controlled by the same gene as in the first population, b) that there are the same two alleles as in the first populations, and c) that the population is in Hardy-Weinberg equilibrium, what proportion of the plants should have pink flowers in this second population? Show your work.
