| Question | Answer |
|---|---|
| what is heredity | the passing on of physical or mental characteristics genetically from one generation to another |
| what is trait | a distinguishing quality or characteristic, typically one belonging to a person |
| what is genetics | the genetic properties or features of an organism, characteristic |
| what is fertilization | the action or process of fertilizing an egg, female animal, or plant, involving the fusion of male and female gametes to form a zygote. |
| what is purebred | an animal bred from parents of the same breed or variety. |
| what is gene | a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring. |
| what is allele | one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome. |
| what is dominant allele | An individual with one dominant and one recessive allele for a gene will have the dominant phenotype. They are generally considered “carriers” of the recessive allele: the recessive allele is there, but the recessive phenotype is not. |
| what recessive allele | For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent. An individual with one dominant and one recessive allele for a gene will have the dominant phenotype. |
| what is hybird | a thing made by combining two different elements; a mixture. |
| what is probability | the extent to which something is probable; the likelihood of something happening or being the case. |
| what is punnett square | The Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment. |
| what is phenotype | the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment. |
| what is homozygous | For each of the organism's thousands of genes, it is either homozygous or heterozygous at that genetic locus. Dominant and Recessive. Alleles can be dominant or recessive. A dominant allele 'dominates over' a recessive allele. |
| what is heterozyous | Heterozygosity occurs when an individual has two different alleles of a gene |
| what is codominace | Alleles that are masked or hidden by dominant alleles are known as recessive alleles. |
| what is mesiosis | 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. |
| what is messenger RNA | the form of RNA in which genetic information transcribed from DNA as a sequence of bases is transferred to a ribosome. |
| what is transfer RNA | is an adaptor molecule composed of RNA, typically 73 to 94 nucleotides in length, that serves as the physical link between the nucleotide sequence of nucleic acids (DNA and RNA) and the amino acid sequence of proteins. |
| what is mutation | the action or process of mutating. |
