Chapter 10: Sexual Reproduction and Genetics Cont. MENDELIAN GENETICS -The parent generation known as the P generation -The offspring of this P cross is calle dthe first filial (F1) generation -The second filial (F2) generation is the offspring of the F1 cross -Mendel studied seven different traits: -Seed or pea color -Flower color -Seed pod color -Seed shape or texture -Seed pod shape -Stem length -Flower position GENES IN PAIRS -Allele -An alternative form of a single gene passed form generation to generation -Dominant -Recessive DOMINANCE -An organism with two of the same alleles for a particular trait is homozygous -An organism with two different alleles for a particular trait is heterozygous GENOTYPE AND PHENOTYPE

Chapter 14 Mendel and the Gene Idea Lecture Outline Overview: Drawing from the Deck of Genes The ?blending? hypothesis popular 1800s This hypothesis proposes that genetic material contributed by each parent mixes in a manner analogous to the way blue and yellow paints blend to make green. With blending inheritance, a freely mating population will eventually give rise to a uniform population of individuals. Everyday observations and the results of breeding experiments tell us that heritable traits do not blend to become uniform. An alternative model: the ?particulate? inheritance proposes that parents pass on discrete heritable units, genes, that retain their separate identities in offspring. Genes can be sorted and passed on, generation after generation, in undiluted form.

Zoe Collins Mrs. G AP Biology 20 March 2014 Pedigree Lab Introduction: Gregor Mendel laid the foundation for our knowledge on genetics, and as time went one scientists continued to confirm and extend Mendel?s ideas. Discoveries on subjects such as DNA structure, mitosis and meioses all explain Mendel?s hypotheses. Mendel demonstrated that genes on different chromosomes, or unlinked genes, are inherited separately under the idea of independent assortment. But due to linked genes gametes are often produced with different combinations of alleles that are different then those of the parents.

Semester 2: Biology Vocabulary Dominant - A comparative term, where one allele is expressed over the other True Breeding- The process of breeding of two organisms with an identical phenotype to procreate an organism with the same phenotype Recessive ? A comparative term, where one allele is not expressed over the other Sexual selection ? A process where mate is chosen based on certain characteristics or traits Homologous structures ? Structures that appear to be similar in different organisms, suggesting a common ancestry or an evolutionary origin. Selective breeding ? A process of breeding for a particular genetic trait Derived structures ? Structures that appear in the ancestor of a group or species, but do not appear in the other species.

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
