DI: Phenotype and Allele Symbols
Phenotypes are the way a trait expresses in an organism
“Expresses” the organism shows this trait
Your phenotype for hair color is the actual color of your hair.
Each phenotype has an allele that produces it
Alleles are just the different forms of a gene.
Alleles are represented by a symbol
The correct symbol for any allele is the first letter of the dominant trait
A capital letter is used for the dominant allele
A lowercase letter is used for a recessive allele
Ex. Purple pea flowers are dominant and white pea flowers are recessive
The flower color allele is symbolized by the letter “P”
(P) for purple
(p) for white
