- 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.The next several questions refer to the data given in this problem. You sample a population of leafhoppers and genotype 250 individuals at a polymorphic locus with two alleles. You obtain the following numbers: AA = 68 individualsAa = 54 individualsaa = 128 individuals What is the frequency of the A allele? (You may round your answer to 2 decimal places)Question 2. A widow's peak hairline is a dominant trait and a straight hairline is a recessive trait. What will be the genotypes and phenotypes of children of a homozygous dominant parent and a heterozygous parent? a) Construct a Punnett Square - List gametes in the area with the dashed line and the genotypes of the offspring in the area with the sold line. b) Genotypes of Children-c) Phenotypes of children-
- Question 3. There are 100 students in a class. Ninety-six did well in the course whereas four blew it totally and received a grade of F. Sorry. In the highly unlikely event that these traits are genetic rather than environmental, if these traits involve dominant and recessive alleles, and if the four (4%) represent the frequency of the homozygous recessive condition, please calculate the following: A) The frequency of the recessive allele. B) The frequency of the dominant allele. C) The frequency of heterozygous individuals. Question 4 Within a population of butterflies, the colour brown (B) is dominant over the colour white (b). And, 40% of all butterflies are white. Given this simple information, which is something that is very likely to be on an exam, calculate the following: A) The percentage of butterflies in the population that are heterozygous. B) The frequency of homozygous dominant individuals. Question 5 A rather large population of organisms have 396 red-sided individuals…Multiple choices: Question: Handedness (whether you are right or left-handed) shows a 79% concordance in monozygotic twins and a 77% concordance in dizygotic twins. Using this information, do you expect handedness to have a large genetic influence? a. No, although the concordance numbers are high, they are similar between MZ and DZ twins b. No, concordance is not 100%QUESTION 29 You are interested in selecting for increased brain size in Fisher cardinals. You’ve chosen three traits that seem to correlate with brain size. a. Calculate the heritability of each trait (H2 = Vg/Vp). Trait: Vg Vp H2 Skull size 1.36 6.08 ______ Ability to find food 5.33 5.98 ______ b.

B) The frequency of homozygous dominant individuals.
- Hardy-Weinberg Problems Please be sure to SHOW ALL WORK in order to get credit. This assignment will be graded for accuracy. *Hint: Remember what p and q represent. Determine first if I am asking for allele frequency or genotype/phenotype frequency. Then determine which equation is appropriate. What does p and q represent in the equations? Which equation do you use if I am asking for allele frequency? If the frequency of the recessive allele is 0.1, what is the frequency of the dominant allele? If the frequency of the dominant allele is 0.4, what is the frequency of the recessive allele? If the frequency of the dominant allele is 0.6, what is the frequency of the homozygous dominant genotype? If the frequency of the homozygous recessive genotype is 0.81, what is the frequency of the recessive allele? If the frequency of the homozygous dominant genotype is 0.25, what is the frequency of the dominant allele? If the frequency of the…42. Kermode bears are found in the central and north coastal regions of British Columbia. Although most Kermode bears have black coats, about 10% of the population have white coats like polar bears. This white coat colour is caused by two autosomal recessive alleles.What is the probability of two black Kermode bears having a male white cub?Answer(Record your answer as a value rounded to two decimal places.)Question 1.You have sampled a population in which you know that the percentage of the homozygous recessive genotype (aa) is 36%. Using that 36%, calculate the following: A) The frequency of the "aa" genotype. B) The frequency of the "a" allele. C) frequency of the a allele, then the frequency is 60%. D) The frequency of the "A" allele. E) frequency of A is by definition equal to p, so the answer is 40%. F) The frequencies of the genotypes "AA" and "Aa." G)The frequencies of the two possible phenotypes if "A" is completely dominant over "a."
