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 Mitosis Meiosis Reproductive System Cells make more cells through the process of …(cell division) Sex cells are created in a process called… Adults produce offspring with the help of which system… Mitosis Meiosis Reproductive System
For this unit, we will look at reproduction with a more specific focus on the passing of traits.
Reproduction Sexual Asexual vs. Specific kingdoms will be discussed in the classification unit 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. Specific kingdoms will be covered in the Classification Unit
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). DNA is found in the nucleoid.

Other Examples of Asexual Reproduction
Types of asexual reproduction
Sexual Reproduction Specific kingdoms will be covered in the Classification Unit
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. Creating offspring with unique combinations of characteristics.
Heredity is the passing of genes from parents to offspring. 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. Review slide about the location of the genetic material from the previous lesson
Sexual Reproduction Each species of living things has a characteristic number of chromosomes. Humans have 23 pairs, for a total of 46 chromosomes.
One Cell Makes Four Cells Sexual Reproduction What is the purpose of Meiosis? What is our general description of Meiosis? Make Sex Cells One Cell Makes Four Cells
23 and Me Watch video—take notes in ISNB https://www.23andme.com/gen101/genes/
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
Sexual Reproduction key words zygote: is a fertilized eukaryotic cell that has received genetic information from two gamete cells (sperm cell and an egg cell) to form a new individual. gametes: cells from each parent that combine to form a zygote. Male gametes are called sperm. Female gametes are called eggs. chromosomes: a DNA molecule that carries all of the hereditary information in the form of genes. genes: basic unit and function of heredity. Act as instructions to make molecules called proteins. Traits: inherited characteristics from parents.
