genetics
| Term | Definition |
|---|---|
| heredity | is the passing of traits to offspring from its parents or ancestor. This is the process by which an offspring cell or organism acquires or becomes predisposed to the characteristics of its parent cell or organism. |
| trait | a distinguishing quality or characteristic, typically one belonging to a person. |
| genetics | relating to genes or heredity.all the cells in the body contain the same genetics |
| purebred | bred from parents of the same breed or variety.animal to |
| gene | a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring. |
| allleles | one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome. |
| dominated allele | an alleles whose trait always shows up in the organism when the allele is present |
| recessive allele | an alleles that is masked when a dominated allele is present |
| hybrid | the offspring of two plants or animals of different species or varieties, such as a mule |
| probability | a number that describes how likely it is that an event will occur |
| punnett sqaure | The Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment. |
| phenotype | the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment. |
| genotype | the genetic constitution of an individual organism |
| homozygous | Relating to a cell that has two identical alleles for a particular trait at corresponding positions on homologous chromosomes. Compare heterozygous. |
| heterozygous | A heterozygous plant would contain the following alleles for seed shape: (Rr). Organisms have two alleles for each trait. When the alleles of a pair are heterozygous, one is dominant and the other is recessive. |
| codominance | We look and act the way we do because of our genes. Genes are units of hereditary information that are located on segments of chromosomes. The genes for a specific trait may exist in different forms known as alleles. An example of an allele or a gene is f |
| meisos | a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores. |
| messenger RNA | the form of RNA in which genetic information transcribed from DNA as a sequence of bases is transferred to a ribosome. |
| transfer RNA | RNA consisting of folded molecules that transport amino acids from the cytoplasm of a cell to a ribosome. |
| mutation | the action or process of mutating. |
