allele: Alternative form of a gene
interkinesis: Period of time between meiosis I and meiosis II during which no DNA replication takes place
homologue: Member of a homologous pair of chromosomes.
sexual reproduction: Reproduction involving meiosis, gamete formation, and fertilization
zygote: Diploid cell formed by the union of two gametes. the product of fertilization.
synapsis: Pairing of homologous chromosomes during meiosis I.
gamete: Haploid sex cell, egg and sperm.
meiosis: Type of nuclear division that occurs as part of sexual reproduction, in which the daughter cells receive the haploid number of chromosomes in varied combinations.
life cycle: ecurring pattern of genetically programmed events by which individuals grow, develop, maintain themselves, and reproduce.
anaphase: Mitotic phase during which daughter chromosomes move toward the poles of the spindle.
angiogenesis: Formation of new blood vessels; one mechanism by which cancer spreads.
apoptosis: Programmed cell death involving a cascade of specific cellular events leading to death and destruction of the cell
asexual reproduction: Reproduction that requires only one parent and does not involve gametes.
aster: Short, radiating fibers produced by the centrosomes on animal cells.
benign tumor: Mass of cells derived from a single mutated cell that has repeatedly undergone cell division but has remained at the site of origin.
binary fission: Splitting of a parent cell into two daughter cells; serves as an asexual form of reproduction in bacteria.
centriole: Cell organelle, existing in pairs, that occurs in the centrosome and may help organize a mitotic spindle for chromosome movement during animal cell division.
Chromatin: Network of fibrils consisting of DNA and associated proteins observed within a nucleus that is not dividing.
Cyclin: Protein that cycles in quantity as the cell cycle progresses, combines with and activates the kinases that function to promote the events of the cycle.
cytokinesis: Division of the cytoplasm following mitosis and meiosis.
interphase: Stages of the cell cycle G1, S, G2 during which growth and DNA synthesis occur when the nucleus is not actively dividing.
metastasis: Spread of cancer from the place of origin throughout the body, caused by the ability of cancer cells to migrate and invade tissues.
autosome: Any chromosome other than the sex-determining pair.
codominance: Inheritance pattern in which both alleles of a gene are equally expressed.
heterozygous: Possessing unlike alleles for a particular trait.
gene locus: Possessing unlike alleles for a particular trait.
recessive Allele: Allele that exerts its phenotypic effect only in the homozygote, its expression is masked by a dominant allele.
pleiotropy: Inheritance pattern in which one gene affects many phenotypic characteristics of the individual.
phenotype: Visible expression of a genotype, brown eyes or attached earlobes.
multifactorial trait: The result of the interaction of several genes, traits.
