QUESTION 1 Which of the following statements is true of a gene and its alleles? A. All genes have only two alleles: a dominant allele and a recessive allele. B. A gene's alleles are the only factors that influence its corresponding phenotype; environment does not play a role. C. A gene may have more than two alleles, which can interact with one another in recessive, dominant, codominant, etc. fashions. D. Two genes can share the same alleles in a phenomenon called pleiotropy.

Question 6 Albinism is caused by an autosomal recessive allele that interferes with skin pigmentation in mammals. Two normally pigmented human parents already have an albino boy. They plan to continue to have children until they get a girl. Some or all of this information is important for each of the questions below. a) What is the probability that their next child (currently unborn) will be a girl with albinism? Explain your reasoning. b) What is the probability their first female child will be albino? Explain your reasoning. c) The answer to part (b) is different (and, yes, the answer is different) from the answer to part (a). Explain why. (Hint: it has something to do with the underlined words.)
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…
QUESTION 43 Which of the following statements is true about linkage disequilibrium? a. D= -0.21 indicates that two loci are in greater LD than D= 0.15 b. New alleles are born into a population in LE with the surrounding loci c. Divergent populations that experience a sudden large migratory event will be immediately in LE after mixing. d. Selective sweeps occur randomly along chromosomes as a result of LE and LD alternating at regular intervals.
QUESTION 8 Morphological differences are abundant among many species. We make assumptions about why adaptations exist, but to understand whether a specific trait is a adaptive and why, researchers must create experiments that have all the following, EXCEPT: a. replication of each treatment to ensure reliability of results. b. hypotheses that are testable and falsifiable. c. include control groups. d. exceedingly small sample sizes in each treatment group. e. experimental design that enables all full interpretation of differences.
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 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."
QUESTION 35 You are conducting a QTL analysis to better understand monkey flower color and shape. To begin you start with breeding a plant that produces a long white tubular flower with purple flat flower. You continue your breeding for many generations. Which of the following is something you most likely observe? a. Variation in flowers your F2 population far exceeded the parental generation characteristics. b. The flower phenotypes did not correlate between siblings and between parent-offspring pairs. c. The variation in phenotypes is greater in the F2 population compared to the F1 population. d. Through selective breeding of the F1 individuals you could not recover the parental generation.
Question 11 D Blue allele Chromosome Brown allele The color of pigeon feathers is a heritable trait that is controlled by different alleles of a single gene as represented in the figure, Blue feather color is dominant to brown feather color. Which of the following statements is true about pigeons with blue feathers and pigeons with brown feathers? They have identical DNA sequences in the feather-color gene. They have identical genotypes for the feather-color gene.
Question 1: In tomatoes, round fruit (O) is dominant to oblong fruit (o). Write as much as possible of the genotypes of: (A) A plant from a homozygous round-fruited stock (B) A plant from an oblong strain (C) A round-fruited plant which resulted from a testcross (D) A oblong-fruited plant which resulted from the cross of two round-fruited ones.
Question 5 A rather large population of organisms have 396 red-sided individuals and 557 tan-sided individuals. Assume that red is totally recessive. Please calculate the following: a) The allele frequencies of each allele b) The expected genotype frequencies. c) The number of heterozygous individuals that you would predict to be in this population. d) The expected phenotype frequencies. e) Conditions happen to be really good this year for breeding and next year there are 1,245 offspring. Assuming that all of the Hardy-Weinberg conditions are met, how many of these would you expect to be red-sided and how many tan-sided?
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 #1 a. Explain why there is a non-Mendelian 2:1 yellow/agouti phenotypic ratio in this cross. b. What is the Raly gene? What does it encode? How does it relate to the lethality of Ay? c. A heterozygous mouse AAy does not produce enough pigment and it is yellow. Homozygous individuals die during development, but AAy heterozygous do not. Why? You may use any graphic aid to explain this, if necessary. This means that you may use a Punnett square or a forking segregation diagram, or computations with fractions.
