Study Notes
Genetic Terminology and Concepts
- Genetics refers to the study of how characteristics are transmitted from generation to generation.
- Allele is a variant form of a gene that may produce differing traits in a phenotype.
- Inheritance describes a characteristic that can be passed from parent to child.
- Heterozygous defines the condition where two alleles of a trait are different, contributing to genetic variation.
- Genotype refers to the pair of alleles present in an individual, determining the genetic constitution.
Mendel's Findings
- In Mendel's monohybrid cross, the F2 generation displayed a phenotypic ratio of 3:1, indicating dominant and recessive traits.
Additional Genetic Terms
- Phenotype encompasses the observable traits of an organism resulting from the interaction of genotype and environment.
- The expected phenotypic ratio from a monohybrid cross between two heterozygous parents is also 3:1.
- Gregor Mendel is the scientist who disproved the blending theory of inheritance, demonstrating that traits are inherited as discrete units.
- A monohybrid cross involves studying the inheritance pattern of a single trait, allowing for controlled observation of dominant and recessive traits.
