- Asexual Reproduction
- involves one parent and results in one or more offspring that are genetically identical to that parent
- Cloning
- a technique that makes identical organisms
- Differentiation
- the process that transforms developing cells into specialized cells with different structures and functions
- Egg
- a sex cell produced by a female
- Embryo
- an organism in the early stages of development (prior to birth)
- Estrogen
- a hormone (produced by the ovaries) that controls female sexual development and the reproductive process
- Expressed
- the way that an unseen gene is seen in an organism as an actual physical trait.
- Fertilization
- the process that combines a sperm cell and an egg cell
- Fetus
- the unborn, developing young of an animal during the later stages of development
- Gamete
- an egg or sperm cell; a sex cell
- Gene expression
- the result of activated genes
- meiosis
- the process that results in the production of sex cells
- Mitosis
- the process that divides the cell's nucleus into two, each with a complete set of genetic material from the parent cell
- Ovaries
- the organ of the human female reproductive system that produces an egg cell, the female gamete
- Placenta
- the organ that enables nutrients and oxygen to pass from the mother's blood to the fetus and waste products to pass from the fetus to the mother's blood
- Progesterone
- a hormone associated with sexual development and the reproductive system
- Recombination
- the additional mixing of genetic material from a sperm and egg which results in a unique combination of genes
- Sex cell
- an egg (female) or a sperm (male)
- Sexual Reproduction
- a method of reproduction that involves two parents to produce offspring that are genetically different from either parent
- Species
- a group of organisms that share certain characteristics and can mate with one another producing fertile offspring
- Sperm
- the male sex cell
- Testes
- the male reproductive organ that produces sperm and the hormone testosterone
- Testosterone
- a hormone associated with the male sexual development and reproduction
- Uterus
- the organ in female animals, where the embryo develops into a fetus
- Zygote
- the cell that results from the joining of the egg and sperm
