Problem 2: Human Pedigree Analysis from Nickerson 11-1 & 11-2 A man and a woman have five children as shown in the following pedigree. 2 heterozygous. 2a. What is the mother's genotype? 2b. What is the father's genotype? The trait responsible for the trait is recessive and symbolized by d, while its dominant counterpart is symbolized by D. 2d. What is the mother's genotype? 2e. What is the father's genotype? 2f. Give the genotypes and their frequencies for the progeny expected from this mating. 2g. For Parts I and II, is this pedigree consistent with the hypothesis that the allele causing the trait is: please Circle ONE. Dominant Either Recessive or Dominant Recessive

Step 1
To determine the mother's genotype, we need to look at the children in the pedigree. Since two of the children are heterozygous, it means that they have one dominant allele (D) and one recessive allele (d). This means that the mother must also be heterozygous (Dd) Show more…

Exercise 6: Pedigree Analysis What is the mode of inheritance for the trait in pedigree A (Figure 4.3), Josal dominant; autosomal recessive or sex-linked? On what basis can you justify your answer? What is the genotype of II-L in pedigree A (Figure 1.3)? Is it possible to determine the genotype of III-8? If so, what is it? What is the likelihood of the trait appearing in the children of 1-1 and 1-2 of pedigree A (Figure 1.3)? What is the mode of inheritance for the trait in pedigree B (Figure 11.4)? On what basis can you justify your answer? Fill in the genotypes for II-2 and II-9 in pedigree B (Figure 11.4). If only one allele is known for an individual, fill in that allele.

EXERCISE 1: Family Pedigree for a Condition Caused by a Dominant Allele Determine the genotype (either AA, Aa, or aa) of the following individuals. If you are unable to determine the genotype: (i) describe the possible genotypes, and (ii) describe what would have to be different about the individual's parents or children in order to make it possible to determine her/his genotype. a. Generation I, individual # 1 b. Generation I, individual # 2 c. Generation II, individual # 4 d. Generation II, individual # 7 e. Generation III, individual # 4

Genetics Problems Solve each of the following genetics problems, showing all work. Assume complete dominance, unless otherwise stated. In pea plants, flowers can be purple or white due to an autosomal gene. Purple is the dominant color, from the allele T. If two plants with genotypes TT and Tt respectively undergo meiosis to form pollen and eggs, what is the genotypic makeup of the gametes for each parent? Note: Mendel's Law of Segregation states that "factors segregate during gamete formation." Gamete(s) from TT plant: Gamete(s) from Tt plant: 2a. Using the information from question #1, what is the phenotypic ratio of flower color from a cross between two white flowering plants? 2b. What is the phenotypic ratio from a cross between two heterozygous, purple flowering plants?
