How do you write alleles?

Answer 1

It will be the lowercase form of the dominant allele. For example the dominant form for tallness is T, the recessive allele for shortness is t.

Answer 2

Alleles are represented by letters, and two letters are used for each gene to denote the alleles inherited from each parent. For example, "Aa" represents a heterozygous individual with one dominant allele (A) and one recessive allele (a) for a particular trait. When writing alleles, uppercase letters are typically used to represent dominant alleles and lowercase letters are used for recessive alleles.

Answer 3

If the allele is dominant, you write the allele as a capital letter. For example dominant allele for dark hair would be DD. You just do the opposite for recessive allels. Ex: dd
