| chromosomes that have a corresponding chromosome from the opposite sex partner | homologous chromosomes |
| chromosome that is not a sex chromosome/ physical characteristics | autosomes |
| one of two chromosomes that determine an individual's sex, females have 2 X chromosomes, males have 1 X chromosome and 1 Y chromosome | sex chromosomes |
| type of reproduction that involves two parents | sexual reproduction |
| a fertilized egg that grows and develops by mitotic cell division | zygote |
| sexual reproduction that involves a type of cell division, four identically unique daughter cells are produced, each a monoploid (haploid) | meiosis |
| the male gamete is called | sperm |
| the female gamete is called | egg |
| the development of mature sex cells | gametogenesis |
| the union of the egg and sperm nuclei | fertilization |
| fertilization that takes place outside the body of the female | external fertilization |
| fertilization that takes place inside if the female | internal fertilization |
| a cell or an organism consisting of two sets of chromosomes, one set from mom and one set from dad | diploid |
| term used to refer to a cell that contains only a single set of chromosomes therefore only a single set of genes | monoploid |
| a group of four closely associated chromatids | tetrad |
| a reproductive cell or sex cell that contains the haploid set of chromosomes | gamete |
| a process occurring during meiosis where two chromosomes pair up | crossing over |
| two genetically identical daughter cells are produced and both daughter cells are diploid | mitotic cell division |
