Question
"How to Solve Genetic Problems"
Using Letters for Alleles
For convenience, the genes of an allele pair are usually symbolized
by a letter from the alphabet. A large letter is used for the dominant trait
and a small letter for the recessive trait. When we want to describe the
genotype of an organism, we use both letters to represent the alleles
inherited from the parents.
For example, free earlobes is a dominant allele and attached earlobes
is recessive. You would use a capital "F" to indicate the dominant allele
and a small “f" to indicate the recessive allele in describing an individual.
