NEET BIOLOGY

Detailed explanation-1: -Dominant alleles are represented by capital letters and recessive alleles are represented by lowercase letters. For example, blue eyes are a recessive trait and brown eyes are a dominant trait.

Detailed explanation-2: -A capital letter represents the dominant allele and a lowercase letter represents the recessive allele. Alleles are all the forms of a gene for any given trait. There are usually two allele possibilities for every trait. For example: B and b are both alleles for the trait of hair color.

Detailed explanation-3: -Dominant alleles are seen as an uppercase of a letter; for example, B. Recessive alleles are seen as a lower case of a letter; b. In order for a person to show the dominant trait, one of the person’s parents must have the dominant trait (which is an uppercase letter).

Detailed explanation-4: -The wild-type allele should be written (underlined or italics) in capital letters (ABC). The full descriptive names of the wild-type (ALPHABETICA) and mutant (alphabetica) alleles should be written in the same manner. Protein products of genes should be written in capital letters without italics (ABC).

Detailed explanation-5: -An allele that is dominant is always shown to be a capital letter and a recessive allele is shown to be the lowercase version of that same letter.
