Reproduction What’s the difference in these two forms of reproduction? White boards: How does sexual and asexual reproduction affect the passing of traits to offspring? Reproduction Cells make more cells through the process of … Mitosis Sex cells are created in a process called… Meiosis Adults produce offspring with the help of which system… Reproductive System For this unit, we will look at reproduction with a more specific focus on the passing of traits. Reproduction Asexual vs. Sexual Asexual Reproduction Asexual Reproduction Most unicellular organisms, and a few multicellular organisms use cell division to reproduce in a process called asexual reproduction. A parent organism produces one or more new organisms that are identical to the parent and live independently of the parent Asexual Reproduction The organism that produces the new organism or organism is the parent Each new organism is an offspring The offspring produced by asexual reproduction are genetically identical to the parent. Asexual Reproduction Asexual Reproduction Binary Fission is a form of asexual reproduction that occurs in cells that do not contain a nucleus (Prokaryotes) Asexual Reproduction Other Examples of Asexual Reproduction Sexual Reproduction Sexual Reproduction Type of reproduction in which two parent cells (male and female reproductive cells) combine to form offspring with genetic material from both cells. A Eukaryotic cell has a Nucleus that contains genetic material. Heredity is the passing of Genes from parents to offspring. A Gene is a section of DNA that provides instructions for specific traits. A Chromosome is the structure that holds the genetic material (DNA). DNA is the genetic material that provides instructions for all the body’s functions. Sexual Reproduction Each species of living things has a characteristic number of chromosomes. Humans have 23 pairs, for a total of 46 chromosomes. Sexual Reproduction What is the purpose of Meiosis? Make Sex Cells What is our general description of Meiosis? One Cell Makes Four Cells Sexual Reproduction The process of Meiosis creates sex cells (sperm and egg in humans) that contain half the genetic material (half the 46 chromosomes) During sexual reproduction, sex cells are combined to form unique offspring. 46 Chromosomes 23 Chromosomes Sexual Reproduction Sexual Reproduction Investigating Reproductive Strategies Activity Comparing Asexual & Sexual Reproduction Essential Question: How does sexual and asexual reproduction affect the passing of traits to offspring?
