Study Notes
Alleles
- Alleles are alternative forms of a gene.
- Dominant and recessive alleles are two types of alleles.
Phenotype
- Phenotype refers to the observable characteristics of an organism.
- This includes physical appearance, such as color.
Genotype
- Genotype represents the complete genetic makeup of an organism.
- It also describes the specific combination of genes for one or more traits.
- Genotypes are often represented using letter combinations.
Heterozygous
- Heterozygous refers to having one copy of each allele for a specific trait.
- An example of a heterozygous genotype is Pp.
Homozygous
- Homozygous describes having two identical alleles for a specific trait.
- This can either be two dominant alleles (PP) or two recessive alleles (pp).
