    Study Notes

    Reproductive Methods and Diversity

    • Sexual reproduction produces genetically diverse individuals through the combination of genetic material from two parents.
    • Asexual reproduction involves a single parent and creates a clone, resulting in genetically identical offspring.
    • Internal fertilization occurs inside the female's body, allowing for development of young that are born alive.
    • External fertilization typically takes place in aquatic environments, where eggs and sperm are released into the water.

    Defining Characteristics of Living Things

    • A defining characteristic of living organisms is their ability to reproduce and give rise to offspring.

    Reproductive Processes

    • The process by which organisms produce offspring is called reproduction.
    • Oviparity is associated with laying eggs outside the body.
    • Ovo-viviparity involves eggs that hatch inside the female's body, leading to live births.
    • Hermaphroditism is a reproductive strategy where an organism has both male and female reproductive structures.

    Genetic Concepts

    • Genetic engineering refers to the direct manipulation of an organism's genes for desirable traits.
    • External fertilization is characterized by the release of sperm and eggs into the environment, allowing fertilization to occur outside the body.

    Specific Reproductive Methods

    • Self-fertilization is a method used by animals with limited mobility, allowing them to reproduce without a mate.
    • In internal fertilization, the male typically fertilizes the egg from the female within her body.
    • A primitive method of reproduction involving a single parent is asexual reproduction.
    • In external fertilization, males and females release their gametes simultaneously into the same area.

    Advantages and Features

    • An advantage of internal fertilization over external is increased protection for developing offspring.
    • A characteristic feature of genetic engineering includes the ability to introduce specific traits or characteristics into an organism.

    Organism Examples

    • Animals that commonly exhibit hermaphroditism include some mollusks and earthworms.
    • Species utilizing ovoviviparity include certain types of sharks and reptiles.
