Reproduction & genetics Donald Winslow 16 September 2010 Readings from Hoefnagels 2009. Biology, McGraw-Hill, New York. Ch. 8 pp 154-163 (cell cycle & mitosis) Ch. 9 pp 174-182 (meiosis & sex) Ch. 10 pp 196-203 (Mendelian genetics)
Reproduction Cellular reproduction Somatic Genome, genes in DNA in nucleus Cell cycle G 1, S, G 2, Mitosis Gametic Meiosis Organismal reproduction
The cell cycle G1G1 S G2G2 M
Organismal reproduction Types of reproduction Asexual Sexual Life cycles Genetics Costs of sexual reproduction Advantages of sexual recombination
Types of reproduction Asexual cloning binary fission budding Ameiotic & meiotic parthenogenesis sexual dioecy (separate sexes) monoecy (hermaphroditism)
Figure 7.1 From Hickman et al. 2006 (13 th ed.)
Generalized sexual lifecycle femalemale Ovum sperm (gametes, 1N) meiosis 2N fertilization zygote (2N) embryo development
Genetics Gregor Mendel Alleles, genes, and genomes Genotype & phenotype Dominance relations among alleles Monohybrid & dihybrid crosses Segregation & independent assortment Human blood groups
Genetic analysis Donald Winslow 25 February 2011 Green peas from Donalds garden.
Mendel’s Laws of Heredity
Mendel’s Law of Heredity
What are we going to talk about today?
Reproduction General Zoology LS February 2011
Why does reproduction require 2 types of cell division?
Chapter 10 Genetic Variability.
WELCOME BACK! Time to jump start your brain! What’s the purpose of mitosis? What’s the purpose of meiosis? How many chromosomes do somatic cells have?
The Essential Question
Gregor Mendel Father of Modern Genetics. Gregor Mendel Father of modern Genetics.
1.Model and explain how genetic information is transferred from one generation of cells to the next via the processes of mitosis and meiosis 2.Compare.
You have body cells and gametes.
Genetics Travis Mackoy. Gregor Mendel 1860s Developed basic principles of genetics Studied genetics of pea plants.
REPORTING CATEGORY 2. #21-PROTEIN SYNTHESIS CHANGES TO DNA CODE.
Genetics. 1. What is a chromosome? 2. Where are chromosomes located? A threadlike structure of DNA and protein that contains genetic information. In eukaryotes.
Meiosis MEIOSIS and sexual life cycles.
Chapter 13 Meiosis. Terms – Heredity Transmission of traits to offspring – Variation Genetic variation in population – Genetics Study of heredity – Genes.
Genetics Chapter 8. Gregor Mendel: Father of Genetics Genetics: study of heredity Heredity: passing traits from parent to offspring Used peas to study.
