A molecule that is present in all living cells. | DNA |
One of the structures in the nucleus that are made up of DNA and Protein. | Chromosomes |
The life cycle of a cell. | Cell Cycle |
the period of the cell cycle during which cell growth and protein synthesis occur. | Interphase |
the process in cell division where the number of chromosomes decreases. | Mitosis |
the division of the cytoplasm of a cell. | Cytokinesis |
Chromosomes that have the some genes and structure. | Homologous Chromosomes |
the process in cell division where the number of Chromosomes decreases to half of it's original amount. | Meiosis |
reproduction that doesn't involve the union of sex cells. | Asexual Reproduction |
reproduction where the sex cells of two parents unite. | Sexual Reproduction |
the union of the male and female gamet to create a zygote | Fertilization |
The passing of genetic material from parent to offspring | Heredity |
one set of instructions for an inherited trait | Gene |
one of the alternative forms of a gene that governs a characteristic | Allele |
the entire genetic makeup of an organism | Genotype |
an organism's appearance or other detectable characteristics | Phenotype |
In, genetics describes an allele that is fully expressed whenever the allele is present in an individual | Domiant |
describes an allele that will be masked unless the organism is homozygous for the trait. | Recessive |
a condition in which two alleles are expressed such that the heterozygous individual is an intermediate of the phenotypes of the two homozygous parents | Incomplete Dominance |
a condition in which two alleles are expressed such that the phenotype of a heterozygous individual is a combination of the phenotypes of the two homozygous parents | Codominance |
a graph used to predict the results of a genetic cross | Punnett square |
the likelihood that a possible future event will occur | probability |
a comparison of two numbers using division | Ratio |
a diagram that shows the occurrence of a genetic trait in several generations of a family | Pedigree |
