TermDefinition
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.
