8) In a population of chimps, a gene that controls the presence or absence of an extra digit on forelimbs is in Hardy-Weinberg equilibrium. This gene has two alleles (D1 and D2), and 40% of the gametes in the chimp population carry the D1 allele. Given this information, what is the percentage of chimps that carry both the D1 and D2 alleles? a.16% b.48% c.60% d.40% e.36%

If the genotype frequencies in a population are 0.60 AA, 0.20 Aa, and 0.20 aa, and if the requirements of the HardyWeinberg principle apply, the genotype frequencies in the offspring generation will be: a. 0.60 AA, 0.20 Aa, 0.20 aa. b. 0.36 AA, 0.60 Aa, 0.04 aa. c. 0.49 AA, 0.42 Aa, 0.09 aa. d. 0.70 AA, 0.00 Aa, 0.30 aa. e. 0.64 AA, 0.32 Aa, 0.04 aa.
When male lions reach sexual maturity, they leave their group in search of a new pride. This can alter the allele frequencies of the population through which of the following mechanisms? natural selection genetic drift gene flow random mating
1.) What happens to the genotypic frequencies from generation 1 to generation 5? 2.) What process is occurring when there is a change in genotypic frequencies over a long period of time? 3.) What would happen if it were more advantageous to be heterozygous (Ff)? Would there still be homozygous fish? Explain. 4.) What happens to the recessive genes over successive generations? Explain. 5.) Why doesn't the recessive gene disappear from the population?
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…
1. A sample of 600 individuals from a population is examined for the presence of the HindIII polymorphism in an autsomal Sca gene. There are two alleles of Sca gene, A and a. The results are 14 individuals are AA, 212 are Aa, 374 are aa. Please answer the following questions accordingly? How many alleles are present in the gene pool in the sample population fort he Sca gene? What are the genotype frequencies? What are the frequencies of A and a alleles? What are the expected numbers of the three genotypes, assuming random
1. Certain flowers are either red (dominant) or white (rr). 91% of the flowers are red. Using the equations, calculate the frequency of the R allele. First you replace R and r for p and q. Thus we know that q2 = .09, because only the homozygous recessives will be white. *changed away from percentages to work the math more easily* What is the frequency of the R allele in this population? 2. In a coastal city in Nigeria, the incidence of Sickle-Cell disease is 4% of the population. Based on this information, what is the frequency of this allele in the population of that city? 3. In a given human population, only the "A" and "B" alleles are present in the ABO system; there are no individuals with type "O" blood or with O alleles in this particular population. If 200 people have type A blood, 75 have type AB blood, and 25 have type B blood, what are the alleleic frequencies of this population (i.e., what are p and q)? 4. An allele W, for white wool, is dominant over allele w, for…
1. What is the expected time to fixation in generations for a new mutation in a diploid population (like humans) with an effective population size of 50? This new mutation is neutral and has no impact on fitness (e.g. synonymous polymorphism). Assuming the mutation isn’t lost immediately, will it reach fixation faster in a population of Ne=500 or Ne=5,000 and why?
1.) Which statement below is not consistent with a population in Hardy-Weinberg equilibrium? A.) Genetic drift is occuring. B.) Random mating is occuring. C.) Population size is large. D.) Migration is not occuring. 2.) Sickel cell anemia is an autosomal recessive genetic disorder. Because individuals affected by sickle cell anemia have defective hemoglobin proteins, their blood cannot transport oxygen properly. There appears to be a relationship between the incidence of malaria and sickle cell anemia. Individuals with sickle cell anemia are carriers of the sickle cell allele have some resistance to malaria. Malaria is caused by the parasite Plasmodium and is transmitted between humans by mosquitoes.” If scientists are successful in significantly reducing or eliminating malaria, the best prediction for what will happen to the allele for sickel cell anemia in the population is that it will: A.)not be affected by the elimination by malaria. B.) increase as its selective advantage…
1. You measure the effects of a single allele (A2) on fitness in two populations of the same plant species, Population X and Population Y. Population X lives at higher altitudes. The average excess of fitness of the A2 allele (aA2) in Population X is 1.21, and the average fitness of the population (w) is 1.0. Population Y lives at a lower altitude. The average excess of fitness of the A2 allele (aA2) in Population Y is -1.68 and the average fitness of the population (w) is 1.0 a) Which population is likely to experience faster evolution? Why? b) What do you predict will happen to the frequency of the A2 allele (pA2) in population X? c) What do you predict will happen to the frequency of the A2 allele (pA2) in population Y? d) Why do you think the average excess of fitness of the A2 allele is different in these two populations?
2) In 1999 suppose that in a field of snapdragons (a type of flower), there are 8000 red snapdragons (RR), 4000 pink snapdragons (RW), and 2000 white snapdragons (WW). In 2016 there are 10000 red snapdragons (RR), 2000 pink snapdragons (RW) and 1000 white snapdragons (WW) a) Calculate the genotypic frequencies of the population in 1999 and in 2016. b) Calculate the allele frequencies of the parent population 1999 and 2016. c) Is micro-evolution occurring?
