parents. Gregor Mendel was the first person who applied the genetic techniques. Question 2 Which option is not one of the observations of Mendel's experiment? O The ratio of the dominant and recessive traits in F2 is 3:1. Both parental phenotypes observed in F1 generation. O The pattern of inheritance was the same for all seven tested traits. O The sex of the parents does not affect the inheritance of a trait in garden peas.

Chapter 14: Mendel and the Gene Idea There are tests to identify carriers that allow couples with a family history of a disorder to make informed decisions about having children. Genetic counseling for these families is based on Mendelian genetics and probability rules. Work through the example of hypo- thetical couple Tyler and Lily on p. 288 of your text to understand the mathematics involved. Then, solve the following problems. 37. Lucia and Jared each have a sibling with cystic fibrosis; neither Lucia or Jared nor any of their parents have the disease. Calculate the probability that a child born to this couple will have cystic fibrosis. Show your work and explain your answer. a. b. What would be the probability if a test revealed that Jared is a carrier, but Lucia is not? Show your work and explain your answer.
EXERCISE 5 MENDELIAN TRAITS IN HUMANS 1 While most human traits are polygenic, the traits in the chart below have traditionally been considered Mendelian traits. More recent research has disputed the single-gene nature of some of these traits, but for the purpose of this exercise, assume that the following traits are Mendelian. Work with a partner to help each other determine your own phenotypes and possible genotypes for these traits. Write your answers in the chart. (Note: Refer to the table on p. 62 for information about these traits.)

Practice Pedigree Problem help. I am confused so please show. Label Phenotypes and genotypes as you go about the Pedigree (and whatever else might be required)! Thank you again for your help, these questions confuse me). Hair or fur length in cats is controlled by a single, autosomal gene; the short hair-allele is dominant to the allele for long hair. Hair color is produced by a different gene which is located on the X chromosome. One allele for this sex-linked gene produces yellow, while an alternate allele produces black fur color; individuals which are heterozygous for these alleles are calico or tortiseshell in color. a). If a long-haired, black male is mated with a calico female homozygous for short hair, what kind of kittens will be produced in the F1generation? Give both genotypes and phenotypes; express the genotypes both symbolically and in words.
NAME: Patterns of Inheritance Worksheet 1. True Breeding Parental Cross A homozygous dominant purple flowered plant is crossed with a homozygous recessive white flowered plant. a. What are the genotypes of the parent plants? (Use the Punnett square to determine the outcomes of this cross. Remember to place the gametes along the left side and top of the square. (P=Purple, p=white) b. What is the genotype of all F₁ plants? 1 b. c. What is the phenotype of all F₁ plants? C. d. How many plants out of 4 will produce white flowers? d. a. 2. Monohybrid Cross: The F₁ offspring from the above problem are allowed to self fertilize. a. What are the genotypes of the F₁ parents? a. (Use the Punnett square to determine the outcomes of this cross. Remember to place the gametes along the left side and top of the square.) b. What is the genotype ratio for this cross? c. What is the phenotype ratio for this cross? d. How many plants out of 4 will produces white flowers? d. b. C.
