(select all that apply) ii IAi IBi IAIB. In what frequencies would you expect the offspring genotypes? . A. Calculate the allele frequencies ( p and q ) Total population = 1612 . Expect female --> eggs m+ w m w+ m+ w+ m w Expected if independent segreg. SURVEY. A) red-eyed mouse (ww) white-eyed mouse (Ww) where you would expect a 1:1 ratio of red eyes to white eyes. Indicate the frequency of each genotype by dragging the labels to the table. a) Calculate the expected allele frequencies and genotype frequencies if the population were in Hardy-Weinberg equilibrium. What other genotypes and in what frequencies would you expect in all offspring from the original parents? What are the genotypes of these individuals? "Epistasis" is when a pair of alleles (i.e. A normal couple has a child affected with Tay-Sachs. Part D: What genotypes would you expect in future offspring from this marriage? The report concludes that, because 3/4 of the offspring of parents who are heterozygous for neurofibromatosis will have the (assume all parental flies are true-breeding). To generalize: if the allele frequencies are p and q, then at Hardy-Weinberg Equilibrium you will have (p + q) X (p + q) = p 2 + 2pq + q 2 as the distribution of the genotypes. Earl has normal color vision, while his wife Erma is colorblind. Selection has removed all a/a genotypes from the population, decreasing the number of a alleles in the population. The son would have an X chromosome with the defective allele producing hemophilia and of course his second sex chromosome would by a Y. Labels may be used once, more than once, or not at all. As there are three phenotypes, this is likely incomplete dominance, with the grey rooster being a blend of the black and white -genotype BW. None of the male or female offspring will have white eyes. a recessive) pair, cover up the expression of a dominant allele at another locus (i.e .

Transcribed image text: PART 4-EVOLUTION OF POPULATIONS Hardy-Weinberg Principle This principle, named after Godfrey Hardy and Wilhelm Weinberg, is a mathematical equation that allows us to predict allele frequencies in a population and see how the frequency of these alleles changes over time (i.e., microevolution). in their offspring. What other genotypes, and in what frequencies, would you expect in offspring from this marriage? Allele A1 converges to 0.667. Learn where . What other genotypes and in what frequencies, would you expect in offspring from this marriage? Examine the Punnett square to determine the other genotypes possible. The Q. Tay-Sachs is an inherited, autosomal recessive trait which involves the inability to properly break down certain lipids. In 1981, a stray black cat with unusual rounded, curled-back ears was adopted by a family in California. If white-eyed female flies are bred to red-eyed male flies, describe the expected offspring (assume all parental flies are true-breeding). In this way, what is the genotypic ratio of the f2 generation? If white-eyed female flies are bred to red-eyed male flies, describe the expected offspring (assume all parental flies are true-breeding). The answer is explained below by taking the specific example of pea plant in both monohybrid and dihybrid cross. 6. Type O blood is the result of two recessive alleles (ii). Their child has type O blood. If you know the frequencies of each genotype, you can calculate the allele frequencies (as in question 6). Blood Type O is recessive. Their child has type O blood. Phenylketonuria (PKU. Imagine that you take one of the black kittens, raise it to maturity, and then mate it with a lilac / beige cat. What are the expected phenotypes of the offspring, and how many of each phenotype woul d you expect to get? Earl has normal color vision, while his wife Erma is colorblind. c) You now take an F1 female and cross her to a true-breeding black, wingless male. Earl has normal color vision, while his wife Erma is colorblind. freq. 32.) Color pattern in a species of duck is determined by one gene with three alleles. If one of the parents is a homozygote for one or more traits, the Punnett Square still contains the same number of boxes, but the . Let us take both monohybrid and dihybrid cross. Under the assumption of Hardy-Weinberg, what is the expected frequency of A 1 A 1? 5.7 on page 135 for an illustration) Given the way this population began, how would you expect the frequency of genotypes in the F1 generation to differ from the frequency of genotypes in the 11 generation as described . What genotypes would you expect in future offspring from this marriage? 60 seconds. Under the assumption of Hardy-Weinberg, what is the expected frequency of A 1 A 1? XB XB Xb XBXb XBXb Y XBY XBY Offspring are expected to be 100% yellow if male, and 100% calico if female. Since each parent provides a single gene all children (100%) will have AO blood. Some of the kittens that you'd get from the above cross are black. Assume two alleles and one locus and arbitrarily name the alleles A and a.You have the genotypic frequencies of two genotypes from the question: Aa = 1/25 = 0.04;AA = 1/2500 = 0.0004. If the same genotype is present in two boxes, its probability of occurring doubles to 1/8 (1/16 + 1/16).
