Term | Definition |
---|---|
Gamete(S) | the cells used during sexual reproduction to produce a zygote. |
Haploid | a cell that contains a single set of chromosomes. |
Oogenesis | the process by which the female are created. |
Ovum/ova | is the female reproductive cell (gamete) |
Sperm | is the male reproductive cell. |
Zygote | cell that's formed by the combination of the male sex cell(sperm) and female sex cell(ovum). |
Tetrad | A four-part structure that forms during the prophase of meiosis and consists of two homologous chromosomes. |
Synapsis | is the pairing of two homologous chromosomes that occurs during meiosis. |
Fertilization | A process in sexual reproduction that involves the combination of the male sex cell(sperm) and female sex cell(ovum) |
Disjunction | is when homologous chromosomes pull apart from each other, |
Gameteogenesis | The development and production of the male and female germ cells required to form a new individual. |
Homologous Chromosome | Homologous chromosomes are chromosome pairs (one from each parent) that are similar in length, gene position, and centromere location. |
Crossing Over | is a process in genetics by which the two chromosomes of a homologous pair exchange equal segments with each other. |
Gonads | the anatomical part of the body where sex cells (gametes) are synthesized. |
Spermatogenesis | the process of male gamete formation including formation of a spermatocyte . |
Polar Bodies | is a small haploid cell that is formed as an egg cell during oogenesis, but which generally does not have the ability to be fertilized. |
Meiosis | is the process by which one diploid eukaryotic cell divides to generate four haploid cells often called gametes. |
Variation | is any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation). |
Nondisjunction | is failure of a pair of homologous chromosomes to separate in meiosis |
Genes | is responsible for the physical and heritable characteristics or phenotype of an organism. |
