In a population of snails, two alleles, T and t, affect the thickness of the shell, and the degree to which the snails are protected from predation. TT individuals have thick shells, which repel predators, and survive best. Tt individuals have medium shell thickness and survive 88% as well as do TT individuals. tt individuals have thin shells and are easy for predators to eat; they survive only 14% as well as do TT individuals. In a population of gametes at the start of a generation, the frequency of the t allele is 0.23. What is the frequency of the t allele in the gametes that will produce the next generation? 91% 77% 23% 18% cannot calculate with the information given 34%
In squirrels, the gray allele (G) is dominant to the brown allele (g) at the coat color locus. A population of 153 squirrels in Pullen Park was scored for the coat color locus. The frequency of the gray allele was found to be 0.81. Due to construction at NC State, 57 NC State squirrels migrated to Pullen Park. The frequency of the gray allele in the NC State squirrels was 0.27. The squirrels mated randomly to form a progeny generation at Pullen Park. Assuming that no further migration occurred and that all other conditions for Hardy-Weinberg equilibrium were met, what is the frequency of the gray allele in the progeny generation at Pullen Park? Round your answer properly to 4 decimal digits. Answer:
1) In cats, the allele for white fur(W) is completely dominant and will result in cats with all white fur in both the homozygous dominant and heterozygous cases. Suppose you look at 50 cats and notice that none of them are completely white. What's the allele frequency for the white fur allele in this population? 2) In carnations, the allele that makes red pigment (R) in flowers is incompletely dominant. Flowers that are red are homozygous dominant and those are pink are heterozygous. White flowers (r) are the result of the recessive allele. Suppose you look at a field of 100 carnations and notice 42 of the plants produce red flowers, 42 have pink flowers, and 16 produce white flowers. What's the allele frequency for both the red (R) and white (r) alleles?
You have cultivated a people-friendly garden of Toxicodendron radicans. The 7 water you used on these plants emanates from the discharge of a leaky, local, nuclear, power plant. Upon studying these plants, you learn that 16% of them can cause death within 2 min of exposure. This killing ability happens to be a recessive trait. Assume the dominant allele confers complete dominance. Find the following: % that do not have this ability Frequency of the recessive allele
Two alleles have been found at the X-linked phosphoglucomutase gene (Pgm) in a Drosophila persimilis population in California. The frequency of the PgmA allele is 0.3, while the frequency of the PgmB allele is 0.7. Assuming the population is at Hardy- Weinberg equilibrium, what are the expected genotype frequencies in males and females?
A population of mealworm beetles (Tenebrio molitor) called the founder generation-consisting of 150 Black (MM) individuals, 100 Brown (Mm) individuals and 250 Orange (mm) individuals-is established on a remote region of Puerto Rico. Mating within this population occurs at random, the three genotypes are selectively neutral and mutations occur at a negligible rate. (a) What are the frequencies of alleles M and m in the founder generation? Frequency of allele M= Frequency of allele m= (b) Calculate p2, 2pq, q2 and the expected number of MM individuals, Mm individuals, and mm individuals in the population, assuming that the population is in Hardy-Weinberg equilibrium
In a Lebanese population, the frequency of the IO allele is 0.67, while the frequency of the D allele (Rh locus) is 0.6. The two loci are independently assorting. What is the frequency of individuals with blood type O+? Assume mating in the population is random
You observe some bark beetles with different feeding behaviors. You find that the behavioral phenotypes you observed are closely associated with the following genotypes. genotype phenotype number observed BB feeds under bark 60 Bb feeds on top of bark 24 bb feeds on leaves 16 a) What are the allele frequencies and the expected number (out of 100 beetles) of genotypes? b) Calculate the Chi-Squared value (c2). Then look up the p-value only using this Chi-squared calculator: https://www.mathsisfun.com/data//chi-square-calculator.html Clear all the values in the box at upper right, enter the Chi Square value that you obtain FROM YOUR CALCULATIONS in the Chi-Square box, and enter 1 for the degrees of freedom. Is the population in H-W equilibrium? c) If you answered “No” to b): Provide at least three biologically valid reasons why the observed beetle population may not be in equilibrium. If you answered “Yes” to b): Why do you think this…
There is a lack of dominance in black (B) and white (W) horse coat colours. An offspring produced from a black horse and a white horse has a blue-roan coat colour (BW). When the blue-roan coat is closely examined, both black and white hair can be found. In an ideal horse population exhibiting Hardy–Weinberg equilibrium, 10 out of every 150 foals have a white coat. Calculate the frequency of the black horse coat allele in the population. Express your answer using two significant digits.
About 7% of men in a population are red-green colour blind due to a sex-linked recessive gene. Assuming random mating in the population with respect to colour blindness; What percentage of women would be expected to be heterozygous?
You decide to examine call duration in Canadian toads at Big Lake near Edmonton. Call duration in the toads is determined by a single autosomal locus "noisy", at which there are two alleles (N & n). You observe three distinct call patterns in the toad population: Long duration, intermediate duration and short duration calls. Based on research from Dr. Phoney Balloni longer calling is dominant to short duration. On one evening at Big Lake you and your socially distanced assistants record the phenotypes of the toads in the table below. Phenotype No. of individuals Long 123 Intermediate 226 Short 101 Determine whether the population is in Hardy-Weinberg equilibrium. a) What are the frequencies of N and n?. b) What are the expected frequencies for each phenotype? c) Is the population is in HW equilibrium?
