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

Biology, 7e (Campbell) Chapter 25: Phylogeny and Systematics Chapter Questions 1) Which combination of the following species characteristics would cause the greatest likelihood of fossilization in sedimentary rock? I. The species was abundant. II. The species was widespread. III. The species had hard body parts. IV. The species was adapted to desert life. V. The species had a long duration in geologic time. A) III only B) III and IV C) I, II, and III D) I, II, and V E) I, II, III, and V Answer: E Topic: Concept 25.1 Skill: Comprehension 2) The ostrich and the emu look very similar and live in similar habitats, however they are not very closely related. This is an example of A) divergent evolution. B) convergent evolution. C) exaptation. D) adaptive radiation.

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

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?

IB Biology Evolution We are all related, one big family in the ?tree of life? We are not just a HUMAN FAMILY ? we are a LIVING family Evolution Do you mean the yeast are OUR distant cousins? Some thoughtful questions? What happened when scientist Paul Nurse added human DNA to the yeast cells? What does this indicate about the evolutionary history of yeast and humans? An interactive website for you to go to Standard 5.4.1 Define Evolution The cumulative change of heritable characteristics of a population Cumulative change ? small changes upon small changes that add up to large changes over long time scales and many generations! Heritable characteristics ? traits controlled by the genes Population ? not an individual 5.4.2
