Heredity
Mendelian Genetics
| Question | Answer |
|---|---|
| Allele | Different forms of a gene for a particular trait |
| Dominant Trait | A trait that will appear in offspring if ONE of the parents contributes it |
| Genotype | An organism's genetic makeup which causes its phenotype |
| Heredity | Transmission of characteristics from parent to offspring |
| Heterozygous | Having two different alleles for a trait, causing the organism to express the dominant trait (Bb) |
| Homozygous | Having two identical alleles for a trait, either two dominant (BB) where the organism expresses the dominant trait or two recessive (bb) where the organism expresses the recessive trait |
| Offspring | The organism that is produced by the parent |
| Phenotype | Outward physical appearance of an organism caused by its genotype |
| Recessive Trait | A trait not expressed in an organism because it is masked by a dominant trait |
| Recombination | A REARRANGEMENT of genes during MEIOSIS |
| Selective Breeding | When organisms are purposely mated to get desired traits |
| Trait | A characteristic of an organism determined by its genes |
| Variation | Characteristics of an organism that differs from members of the same species |
