Study Notes
Key Concepts in Mouse Genetics
- Allele: Different forms of a gene that dictate variations in traits.
- DNA: Known as deoxyribonucleic acid, it is the molecular blueprint for genetic information, residing in the cell nucleus.
- Dominant Allele: An allele that expresses its trait whenever present in the genotype.
- Gene: Fundamental hereditary unit passed from parent to offspring, influencing traits.
- Genotype: The collection of alleles in an organism that defines its genetic makeup for specific traits.
- Heredity: The process through which genetic traits are transferred from parents to their offspring.
Allele Combinations
- Heterozygous: Describes an organism with two differing alleles for a particular trait, leading to variability in expression.
- Homozygous: Refers to an organism possessing two identical alleles for a trait, resulting in consistent trait manifestation.
- Hybrid: An organism characterized by having different alleles for a trait, similar to heterozygous.
Genetic Processes
- Inheritance: Mechanism of transferring physical and biological traits from parents to offspring.
- Phenotype: The observable characteristics or physical expression of an organism determined by its genotype.
- Punnett Square: A visual tool used to predict the allele combinations and genotypes resulting from a genetic cross.
- Recessive Allele: An allele whose effect is overshadowed by the presence of a dominant allele, only expressing in a homozygous state.
Traits in Genetics
- Trait: A specific characteristic that can be passed down from parents to offspring through genetic inheritance.
