1. Describe Mendel’s P, F1, and F2 generations in his experiments with pea plants.
2. Describe Mendel’s rule of segregation in your own words.
3.Two heterozygote tongue rollers (dominant trait) have a child. What percentage of individuals would be predicted to be heterozygotes, homozygous dominant and homozygous recessive? What is the only genotype of two parents that would ensure that their offspring could not roll their tongue (recessive trait)? Explain your reasoning.
4. List the stages of meiosis I and meiosis II, indicating the point at which the cell becomes haploid. Why does it become haploid at this point?
5. A man with AB blood and a woman with O blood have a child. What is the genotype and phenotype of both the man and woman? Is it possible for them to have a child with O blood? Explain. Also, explain what type of inheritance the ABO blood system demonstrates.
6. Cystic fibrosis is an autosomal recessive disease characterized by two copies of a mutated CFTR gene. If one in 100 people in the United States have cystic fibrosis and one in 5.0505050505 people are carriers for cystic fibrosis, calculate the number of individuals that are homozygous dominant. In other words, how many people would have two copies of the normal (non-mutated) CFTR gene. Use the Hardy-Weinberg equation and explain how you determined this.
7. Red-green colorblindness is a recessive trait that is located on the X chromosome. A woman who is not colorblind but whose father is colorblind has a child with a man who is not colorblind. Predict the probability of their daughter having colorblindness, their daughter having normal vision, their son being colorblind, and their son having normal vision. Explain your reasoning. .
8. What is genetic engineering? Describe one application of genetic engineering that affects your everyday life.
