Study Notes
Genetics Vocabulary
- Dominant: Represents the stronger gene, usually denoted by a capital letter, exerting influence over its counterpart.
- Recessive Gene: Considered the weaker gene, represented by a lowercase letter, only expressed when both alleles are recessive.
Genetic Compositions
- Hybrid: An organism with two different alleles (e.g., Aa), combining traits from both dominant and recessive genes.
- Purebred: An organism with identical alleles (e.g., DD or dd), ensuring uniform traits across generations.
Gene Inheritance
- Organisms receive genetic material equally from both parents, with half of the genetic contribution coming from the mother and half from the father.
Genetics Terminology
- Genotype: Describes the genetic makeup of an organism, represented by combinations of letters that indicate alleles (e.g., AA, Aa, or aa).
- Phenotype: Refers to the observable physical characteristics or traits of an organism, such as eye color or height, resulting from the genotype.
Genetic Tools
- Punnett Square: A diagram used to predict the possible genetic combinations and outcomes of a cross between two organisms, illustrating the probabilities for genotypes and phenotypes.
