- QUESTION 2 A male hare with the genotype AaBb is crossed with a female hare with the genotype AABb. Use a Punnet square to determine the genotypes, phenotypes and proportions in the offspring. Show all your working. [17] A = black hair a = yellow hair B = brown eyes b = blue eyesQUESTION 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 5. The pedigree below follows the appearance of a rare autosomal dominant condition resulting in malformation of limbs through a family. What is the penetrance of this trait? i.e., What is the ratio between the number of individuals in the pedigree who display the trait (numerator) and the number of individuals you know from the pedigree must have the trait-determining genotype (denominator)? Enter your answer in the form of a fraction without any spaces. e.g., If your answer is “one-fourth”, enter: 1/4
- Question 6: If individuals IV-4 and IV-5 mate and have a child, what is the probability that the child will have the genetic condition? Assume people mating into the pedigree do not carry the abnormal allele unless information given in the pedigree suggests otherwise. Write the probability as a fraction without any spaces, answers given as a decimal will be marked incorrect. (For example write your answer as 5/72 – note that is NOT the correct answer).Question 1 refers to the pedigree chart in Figure 11.2 for a family, some of whose members exhibit the dominant trait, W. Affected individuals are indicated by a dark square or circle. 1) What is the genotype of individual II-5? What are the genotypes of individuals II-2, 3, and 4 and II-6, 7, and 8?Question 1: In celery the leaves can be curly (Dominant; L) or straight (recessive; l). Another trait is spots on the leaves.

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 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.

- QUESTION 1. Plant A is 2n = 40, and plant B is 2n = 42. If crossed, they produce a hybrid plant. How many chromosomes are found in a somatic cell of the hybrid? a) 42 b) 82 c) either 40 or 42, depending on which plant was female d) 41 e) 40Question 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 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.)
