Asexual vs. Sexual Reproduction
Sexual reproduction results in diverse offspring due to genetic variation, which increases a species' ability to adapt to changing environments. It also enables selective breeding, allowing humans to develop plants and animals with desirable traits such as disease resistance or higher yield.
Advantages of Sexual Reproduction
Diverse offspring - genetic variation among offspring
Selective breeding- Used to develop many types of plants and animals that have desirable traits

Disadvantage of Sexual Reproduction
Time and energy- time to grow and develop to age of reproduction, find a mate, time during pregnancy where animals cannot reproduce
Examples of Sexual Reproduction
Dogs, Flowers, Birds, Spiders, Snakes, Trees
Asexual Reproduction
One parent organism produces offspring without fertilization
Forms offspring that are genetically and physically identical
Fission
Type of asexual reproduction
Cell division in prokaryotes that forms two genetically identical cells
Ex.) Bacteria, Ecoli, Pond critters
Budding
Type of asexual reproduction
A new organism grows by mitosis and cell division on the body of its parent
Ex.) Yeast, Hydra, cactus

Compare/Contrast Asexual and Sexual Reproduction | Asexual and sexual reproduction both are forms of forming new offspring of that species. Asexual reproduction needs only one organism in order to reproduce more offspring that are identical to each other and the parent. Sexual reproduction involves a male and female cell combining to form offspring that are genetically unique to each other parents. |
Meiosis vs. Mitosis | Meiosis and Mitosis both form new cells. Mitosis is used for repair and growth forming identical cells while meiosis is used to form sex cells that are unique to each other. Meiosis involves Interphase P1M1A1T1, P2M2A2T2. Mitosis involves Interphase PMAT and cytokinesis. |
Diploid | Cells that have pairs of chromosomes |
Haploid | Cells that have only one chromosome |
Sex Cell | Also known as gametes, sperm and egg that combine to form a zygote |
Fertilization | Combination of egg and sperm cell. |
Egg | Female sex cell formed in the ovary |
Sperm | Male sex cell formed in the testi |
Nucleus | Organelle in the cell that hold the genetic material within the cell (eukaryotic cells only) |
