Gregor Mendel Studied traits that occur in distinct forms. Developed true-breeding varieties When bred amongst themselves these plants produced offspring identical to the parent for that trait. Used mathematical analysis in his studies. Definitions Gametes: reproductive cells produced by sexually reproducing organisms. Two types: male gametes = sperm In plants: contained in pollen Female gametes = eggs In plants: contained in ovules which mature to seeds when fertilized Ovules contained in carpels Fertilization Fertilization: fusion of egg and sperm Self-fertilized: fusion of sperm and egg from same plant Cross fertilized: fusion of egg and sperm from two different plants Produced hybrids F1: first generation F2: second generation Mendel?s Model

1. The half-life of Carbon-14 decaying to Nitrogen-14 is 5,730 years. A mammoth bone fossil found in Siberia appears to be 22,920 years old. If these fossils now contain 6 grams of C-14, how much C-14 did they contain when this mammoth died? 22,920 6 17,190 12 11,460 24 5,730 48 1 96 22,920 / 5,730 = 4 half lives OR end = starting amount / 2 ^ half-lives 6 = start / 2 ^ 4 6 = start / 16 96 = starting amount 2. A disease is controlled by a single gene with two alleles. Assume Hardy-Weinberg equilibrium for this gene. If one in 2,000 monkeys have albinism, what is the ratio of heterozygous carriers to those with the disease? P^2 + 2pq + q^2 = 1

Cambell biology 9th Edition Chapter 14 Test bank

Campbell's Biology, 9e (Reece et al.) Chapter 14 Mendel and the Gene Idea The questions in Chapter 14 are mostly at the Application/Analysis skill level. The material in the chapter invites students to apply Mendel?s laws, and by doing so encourages problem solving. Because of the human-related Concept 14.4, a fair number of Synthesis/Evaluation questions are included as well. Very little of the chapter lends itself to Knowledge/Comprehension questions only. In addition, to help students make maximum use of information presented about one or more specific traits, a greater number of questions than usual is grouped together to explore brief scenarios or figures. Multiple-Choice Questions 1) What do we mean when we use the terms monohybrid cross and dihybrid cross?
