Biology Semester 1 Final Study Guide A group of students wants to determine if different types of music affect the growth rate of plants. They expose one group to two hours of classical music, a second group to two hours of rock music, a third group to country music, and a fourth group to no music. Identify the following: independent variable, dependent variable, constants, and control. What are the 3 principles of the cell theory? Compare and contrast animals and plant cells. Animal Cells Plant Cells Describe the functions of nucleus, ribosome, chloroplast, mitochondria, endoplasmic reticulum, and golgi apparatus. Draw the cell membrane and label the proteins, phospholipids, cholesterol and carbohydrates.

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?

Pedigree Analysis * A pedigree is a family tree that describes the interrelationships of parents and children across generations * Inheritance patterns of particular traits can be traced and described using pedigrees * Pedigrees can also be used to make predictions about future offspring * We can use the multiplication and addition rules to predict the probability of specific phenotypes Recessively Inherited Disorders * Many genetic disorders are inherited in a recessive manner * These range from relatively mild to life-threatening The Behavior of Recessive Alleles * Recessively inherited disorders show up only in individuals homozygous for the allele * Carriers are heterozygous individuals who carry the recessive allele but are phenotypically normal

Probability laws govern Mendelian inheritance * Mendel?s laws of segregation and independent assortment reflect the rules of probability * When tossing a coin, the outcome of one toss has no impact on the outcome of the next toss * In the same way, the alleles of one gene segregate into gametes independently of another gene?s alleles The Multiplication and Addition Rules Applied to Monohybrid Crosses Figure 14.9 * The multiplication rule states that the probability that 2 or more independent events will occur together is the product of their individual probabilities * Probability in an F1 monohybrid cross can be determined using the multiplication rule

Mendel and the Gene Idea Drawing from the Deck of Genes * What principles account for the transmission of traits from parents to offspring? * The ?blending? hypothesis is the idea that genetic material from the two parents blends together (like blue and yellow paint blend to make green) * The ?particulate? hypothesis is the idea that parents pass on discrete heritable units (genes) * Mendel documented a particulate mechanism through his experiments with garden peas Concept 14.1: Mendel used the scientific approach to identify two laws of inheritance * Mendel discovered the basic principles of heredity by breeding garden peas in carefully planned experiments Mendel?s Experimental, Quantitative Approach

Mendelian Genetics: How Genetics Began Commonly referred to as the ?father of modern genetics? Gregor Mendel, born in 1822 in what is now the Czech Republic, published the first known findings of heredity in 1866. His primary findings were based on the study of pea plants during his 14 year tenure as an Austrian monk in charge of the monastery garden. Mendelian Genetics

Genetics An organism is heterozygous at two genetic loci on different chromosomes. Explain how these alleles are transmitted by the process of mitosis to daughter cells. Explain how these alleles are distributed by the process of meiosis to gametes. Explain how the behavior of these two pairs of homologous chromosomes during meiosis provides the physical basis for Mendel?s two laws of inheritance. Labeled diagrams that are explained in your answer may be useful.
