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)

Reproduction General Zoology LS February 2011
Chapter 10 Meiosis and an INTRODUCTION to GENETICS Making Sex Cells (Gametes) and Genetics MHS Biology 2015.
Gregor Mendel Father of Modern Genetics. Gregor Mendel Father of modern Genetics.
6.6 Meiosis and Genetic Variation KEY CONCEPT Independent assortment and crossing over during meiosis result in genetic diversity.
Genetic analysis Donald Winslow 25 February 2011 Green peas from Donalds garden.
The Basis of Heredity Inheritance and Meiosis. Definitions Genetics = study of genes, the units on chromosomes that code for traits Heredity = study of.
Chapter 11-4 Meiosis. Let’s make a sex cell! Meiosis – Production of haploid gametes Meiosis – Production of haploid gametes Diploid- has paired chromosomes.
Meiosis and Mendel Chapter KEY CONCEPT Gametes have half the number of chromosomes that body cells have.
Mitosis vs. Meiosis. What is the difference Mitosis is asexual reproduction. Does not produce a new organism. Mitosis is asexual reproduction. Does not.
Genetics Travis Mackoy. Gregor Mendel 1860s Developed basic principles of genetics Studied genetics of pea plants.
Asexual vs. Sexual Reproduction. Parent cell first copies its DNA Then divides into 2 separate cells New cells have a complete copy of parent’s.
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?
Population Dynamics Humans, Sickle-cell Disease, and Malaria How does a population of humans become resistant to malaria?
Mendel’s Laws of Heredity
Genetics. Gregor Mendel: Father of Genetics Genetics: study of heredity Heredity: passing traits from parent to offspring Used peas to study heredity.
Mendelian Genetics Gregor Mendel “The Father of Genetics” He experimented with garden peas Easy to grow & control mating experiments observed one trait.
Chapter 13:Meiosis. Heredity 4 Heredity: the transmission of traits from one generation to the next 4 Asexual reproduction: clones 4 Sexual reproduction:
6.1 Chromosomes and Meiosis KEY CONCEPT Gametes have half the number of chromosomes that body cells have.
Probability & Genetics. .A. Learning goals Explain the random process of chromosome segregation and distribution of alleles in gametes. Predict possible.
MEIOSIS AND SEXUAL LIFE CYCLES CH 13. I. Overview of Reproduction Asexual reproduction: produces identical offspring (budding, cloning, binary fission/mitosis)
Why does reproduction require 2 types of cell division?
Mendel’s Laws. Essential Questions 1. Who is Gregor Mendel? 2. What happened in Mendel’s monohybrid cross experiment? 3. What happened in Mendel’s dihybrid.
Chapter 13 Meiosis. Terms – Heredity Transmission of traits to offspring – Variation Genetic variation in population – Genetics Study of heredity – Genes.
Chapter 10 Genetic Variability.
Meiosis MEIOSIS and sexual life cycles.
Domain III Genetics. DNA Nucleic Acids and Nucleotides Adenine/Thymine Guanine/Cytosine Double Helix Location: Nucleus.
Mendel’s Law of Heredity
Meiosis 15 October, 2004 Text Chapter 13. In asexual reproduction, individuals give rise to genetically identical offspring (clones). All cell division.
Genetics Review 23 How many pairs of chromosomes do humans have?
Genetics Learning Goals 1. Describe Gregor Mendel 2. List the two things that increase genetic variation. 3. Understand the Law of Dominance.
Click on a lesson name to select. Section 1: Meiosis Section 2: Mendelian Genetics Section 3: Gene Linkage and Polyploidy Chapter 10 Sexual Reproduction.
You have body cells and gametes.
Meiosis Notes 4 Cell division to form the gametes, sperm (male gamete) and egg (female gamete). 4 Normal cells are diploid: 2 copies of every gene. 4 Gametes.
Mendel and Meiosis Chp 10 Pp Contents 10-2 Meiosis 10-1 Mendel.

Chapter 13 Meiosis. Living Things Reproduce Results in similarities and differences between offspring and parents Facilitated by heredity or inheritance.
EOCT Review Day 2: Genetics.
Heredity. The passing of genetic information from one generation to the next generation.
KEY CONCEPT – Section 6.1 Gametes have half the number of chromosomes that body cells have.
Reproduction in Cells. One parent Creates clones Parent gives entire genetic make-up to offspring Examples: Binary Fission – Prokaryotes Mitotic Cell.
REPORTING CATEGORY 2. #21-PROTEIN SYNTHESIS CHANGES TO DNA CODE.
Nicholas Olofsson and Elissa Harris Period 3. Meiosis Process that converts diploid nuclei into haploid nuclei Occurs in the sex organs-testes and ovaries.
Understanding Biological Inheritance GREGOR MENDEL.
Genetics Chapter 8. Gregor Mendel: Father of Genetics Genetics: study of heredity Heredity: passing traits from parent to offspring Used peas to study.
Fundamentals of Genetics (Ch ) Genetics is the field of biology devoted to understanding how characteristics are transmitted from parents to offspring.
REPRODUCTION BC SCIENCE 9. Ministry Key Elements By the end of the grade, students will have developed understanding of the processes of cell division.
Meiosis and Sexual Reproduction
Genetics Chapter 11. What is Genetics Genetics is the scientific study of heredity. Heredity is what makes each species unique.
