Let’s suppose that pigmentation in a species of insect is controlled by a single gene existing in two alleles, D for dark and d for light. The heterozygote Dd is intermediate in color. In a heterogeneous environment, the allele frequencies are D = 0.7 and d = 0.3. This polymorphism is maintained because the environment has some dimly lit forested areas and some sunny fields. During a hurricane, a group of 1000 insects is blown to a completely sunny area. In this environment, the fitness values are DD = 0.3, Dd = 0.7, and dd = 1.0. Calculate the allele frequencies in the next generation.
Do a chi square tablet for the question. I left a reference down below. Question: 3. In dihybrid cross where both parents were heterozygous for both traits, the following data was obtained: 890 dominant for both traits, 97 recessive for both traits, 315 dominant for trait 1, but recessive for trait 2, and 298 dominant for trait 2, but recessive for trait one. Perform a chi-square analysis to determine if this data agrees with the expected outcomes. State your null hypothesis as well as if the null is rejected or not.
Assume for simplicity that height is a discrete characteristic that is affected most strongly by a single locus with two alleles, T and S. Homozygous TT are taller than average, heterozygous TS are of average height, and homozygous SS are shorter than average. a) In the Dutch population, the results of height on fertility in males is an example of heterozygote advantage, heterozygote disadvantage, general dominance, selection against a dominant phenotype, or selection against a recessive phenotype? b) Would your answer above change for the Dutch women? c) What about the American men and women? d) Can you provide an explanation for the discrepancies in this phenomenon between the Dutch and American populations?
If a trait determined by autosomal recessive allele occurs at a frequency of 0.25 in a population, what are the allelic frequencies? Assume Hardy-Weinberg equilibrium and use A and a to symbolize the dominant and recessive alleles, respectively. Show calculation.
Which of the following statements is not true about heritability? a. H^2 is always a number between 0 and 1 b. H^2 =1 indicates most variation in a trait among individuals due to variation in genes c. H^2 means what fraction of variation in a trait is due to variation in genes and what fraction is due to variation in environmental conditions d. H^2 =1 indicates most variation in a trait among individuals due to variation in environments
In a population at Hardy-Weinberg equilibrium, 190 out of 1000 individuals have polydactyly. Note that the trait is dominant. a. What is the frequency of the dominant and recessive alleles? b. How many are expected to be heterozygotes for the trait? c. How many are expected to be homozygous dominant?
If 83% of the Elmo Muppet population has a condition that makes them refer to themselves in the third person, and you know that this condition is the result of the homozygous recessive genotype (ee)… Assuming Hardy-Weinberg equilibrium, what is the allelic frequency of the dominant allele (E)? ______ Assuming Hardy-Weinberg equilibrium, what percent of the phenotypically normal population of are carriers of the recessive allele? ________ (NOTE this is asking for # that carry the allele/total "normal" population) In your answer, clearly answer with a number for both 1) and 2). Show calculations.
In 1927, the ophthalmologist George Waaler tested9049 schoolboys in Oslo, Norway, for red-green colorblindness and found 8324 of them to be normal and725 to be color blind. He also tested 9072 schoolgirlsand found 9032 that had normal color vision while40 were color blind.a. Assuming that the same sex-linked recessive allelec causes all forms of red-green color blindness,calculate the allele frequencies of c and C (the allelefor normal vision) from the data for the schoolboys.(Hint: Refer to your answer to Problem 12a.)b. Does Waaler’s sample demonstrate Hardy-Weinbergequilibrium for alleles of this gene? Explain youranswer by describing observations that are eitherconsistent or inconsistent with this hypothesis.On closer analysis of these schoolchildren, Waalerfound that there was actually more than one c allelecausing color blindness in his sample: one kind forthe prot type (cp) and one for the deuter type (cd).(Protanopia and deuteranopia are slightly differentforms of red-green…
Recall that the alleles for blood groups are A, B, O, and that A and B are each dominant to O, and A and B are codominant (AA and AO= A blood type; BB and BO = B blood type; AB = AB blood type; OO = O blood type). According to the Red Cross, in the US Asian population the alleles frequencies of A, B, an O are 18.8%, 17.6%, and 63.6%, respectively. If a mother and son from this population have blood type AB and the father has blood type B, what is the probability that the father’s genotype is BB?
. In pea plants, height is controlled by a Dominant Allele (T) for Tall Height and by a Recessive Allele (t) for Short Height. If 96% of a population of pea plants have the tall phenotype, calculate the frequencies of dominant allele (T) & recessive (t) alleles. Out of the 96%, what is the estimation of how many are homozygous dominant vs. heterozygous? What is the frequency of the recessive phenotype?
If the frequency of an allele at a locus of interest is 0.57, and we know there are only two alleles at this locus, what must be the frequency of the other allele?
