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 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:- 3. Wild type Drosophila has red eyes and gray body*. Autosomal recessive mutations sepia (se) and ebony (e) modify the eye and body color, respectively. What kind of a cross (or crosses) can you set up to determine whether the two genes are linked? You have several lines to choose from: a pure-breeding wild type line (where alleles for both, sepia and ebony are wild type), a double homozygous recessive line, a pure breeding sepia mutant line and a pure breeding ebony mutant line. You don’t have to use all of them. (a) Write down the cross (or crosses, if necessary) which will allow you to determine linkage; include genotypes of both crossed individuals (b) What kind of results (offspring) do you expect if the two genes are linked? (c) What kind of results (offspring) do you expect if the two genes are not linked? For (b) and (c), state the phenotypes, genotypes and numbers.
Question 1 Given that the passing of alleles into gametes is random, if we observe one gamete (egg or sperm) of an individual at a specific gene/locus: What is the probability that the allele in that gamete is the one from the father of the individual making the gametes? 2. What is the probability that the allele in that gamete is the one from the mother of the individual making the gametes?
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. Why would multi-gene families complicate things in terms of being sure of which member of the family was responsible for a particular phenotype?
question- Color blindness is inherited as a sex-linked recessive disease. A normal male marries a female who is heterozygous for the trait. What percentage of their sons will exhibit color blindness?
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: 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 14 Antibiotic resistance is an example of a(n) 1. allele 2. phenotype 3. genotype
Question 12 In a series of crosses involving pea plants that have round or wrinkled seeds (round is dominant to wrinkled) and yellow or green seeds (yellow is dominant to green), the following ratios were observed in the progeny: Parents -----> Progeny a) round, green x wrinkled, yellow -----> 100% round, yellow b) round, yellow x round, yellow -----> 9/16 round, yellow 3/16 round, green 3/16 wrinkled, yellow 1/16 wrinkled, green c) round, yellow x round, yellow -----> 3/4 round, yellow 1/4 wrinkled, yellow d) wrinkled, yellow x round, yellow -----> 6/16 wrinkled, yellow 2/16 wrinkled, green 6/16 round, yellow 2/16 round, green On the basis of these progeny ratios, determine a possible genotype for each of the parent plants in each set of crosses (a,b, c, and d). Sometimes more than one genotype is possible, but you need only suggest one.
Question 10. Identify the three ways that a karyotype can be organized.
Question 68 Sister chromatids are best described as two chromosomes having the same genes in the same order but having different alleles. the same alleles of the same genes in a different order. different genes in the same order and possibly having different alleles of some genes. different alleles of the same genes arranged in a different order. an identical DNA sequence. Question 69 During what phase of meiosis do the homologous pairs of chromosomes line-up in the middle of the cell with the help of spindle fibers?
