5 Questions
What is the definition of Mendelian genetics?
Refers to one gene that dictates one characteristic and has two alleles: one dominant allele and one recessive allele
What is an example of incomplete dominance in humans mentioned in the text?
Hypercholesterolemia
What is the characteristic of incomplete dominance?
Both alleles are dominant
How does Mendelian genetics differ from complex genetics in terms of gene influence?
Mendelian genetics refers to one gene dictating one characteristic, while complex genetics involve multiple genes influencing one characteristic
What is the risk factor associated with Hypercholesterolemia mentioned in the text?
Heart disease
Study Notes
Mendelian Genetics
- Definition: The study of the inheritance of traits based on the laws of inheritance discovered by Gregor Mendel, which states that each trait is determined by a single gene with two alleles (different forms of the gene)
Incomplete Dominance
- Example in humans: Free earlobe vs. attached earlobe
- Characteristic: The dominant allele does not completely mask the effect of the recessive allele, resulting in a combination of both traits
Comparison to Complex Genetics
- Mendelian genetics: One gene controls one trait, with two alleles influencing the trait
- Complex genetics: Multiple genes interact to influence a single trait, with many alleles contributing to the trait
Hypercholesterolemia
- Risk factor: High levels of low-density lipoprotein (LDL) cholesterol, which can lead to cardiovascular disease
