Question

What is a dominant trait?

Answer 1

Trait:

• The traits are the characteristics expressed by the individuals of a particular species.
• The traits are coded by genes. Each gene has two variants which are known as alleles.

Dominant trait:

• The dominant allele decides the appearance of the characters or the trait. It ignores the presence of the alternative allele.

Representation and example:

• The dominant trait is represented by a capital letter.
• For example, Rr controls the shape of the seed, then R is the dominant gene for the roundness of the seed, and r codes for wrinkled seed.
