Study Notes
Non-Mendelian Inheritance
- Characterized by inheritance patterns that do not adhere to Mendel's principles.
Incomplete Dominance
- Results in offspring displaying a phenotype that is a blend of the parents' traits rather than one trait being dominant over the other.
Codominance
- Both alleles in a heterozygote are expressed fully and simultaneously, leading to a phenotype that showcases features from both alleles.
Sex-Linked Traits
- Genes associated with sex chromosomes can influence traits, with expressions related to gender.
- Sex-influenced traits: Autosomal traits affected by the sex of the individual but not located on sex chromosomes.
- Sex-limited traits: Autosomal traits whose expression is restricted to one sex.
Multiple Alleles
- Involves more than two alleles controlling the expression of a trait.
- Ishihara test plates are employed to assess color vision deficiencies such as color blindness.
Monogenic Inheritance
- Involves a single gene determining a trait.
- Polygenic (Multiple gene) inheritance: Traits are governed by multiple genes, leading to a wider range of phenotypes.
Additive Alleles
- Refers to the cumulative effect of alleles where inheriting more copies results in more pronounced traits.
Biodiversity in the Philippines
- Endemic species: Unique species that are native to a specific geographical region and not found elsewhere.
- Endangered species: Species with low populations at risk of extinction.
- Extinct species: Organisms that no longer exist on Earth.
- Species richness: Measurement of the number of different species present in a given area.
