Ch 46 Sexual Zygote ? fertilized egg Gamete- sex cell Egg Sperm Asexual Most animals do sexy only, but some do asex or both Mechanisms of Asex reproduction Invertebrates Fission-separation of a parent organisms into 2 individuals of equal size Sea anemone Budding- new individuals come from outgrowth of existing ones Corals Fragmentation and regeneration Sponges, cnidarians Parthenogenesis-asex where egg develops without being fertilized Bees, wasps, ants Haploid ? no meiosis occurred, no fertilization occurred, becomes adult that makes either egg or sperm. ? mainly male in honeybee and some ant populations Diploid- develop from fertilized eggs, becomes adult- worker ant or bees

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

Chapter 13 Meiosis and Sexual Life Cycles Lecture Outline Overview: Hereditary Similarity and Variation Living organisms are distinguished by their ability to reproduce their own kind. Offspring resemble their parents more than they do less closely related individuals of the same species. The transmission of traits from one generation to the next is called heredity or inheritance. However, offspring differ somewhat from parents and siblings, demonstrating variation. Farmers have bred plants and animals for desired traits for thousands of years, but the mechanisms of heredity and variation eluded biologists until the development of genetics in the 20th century. Genetics is the scientific study of heredity and variation.

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?

2 of 13 PCR. Polymerase chain reaction is used to copy DNA. Cycle 1: - A sample of DNA is added to detergent to release the DNA from cells. - DNA polymerase, DNA primers with fluorescent markers and nucleotides are added. - (at 95 degrees) the DNA splits into two strands. - (at 55 degrees) primers attach at the start of the STR repeated sequence. - (at 70 degrees ) DNA polymerases attach nucleotides are added the DNA sequence is replicated. 1 of 13 DNA profiling. Non coding blocks in DNA are called introns, and the coding regions are called exons. In introns DNA sequences are repeated many times, this is called short tandem repeats (STR's). A DNA profile is produced using gel electrophoresis, In which DNA fragments produced by
