What do you know about a Genotype?

Tip!

Genotype: refers to the genetic characteristics of an organism

Genotype

• Genotypes always have 2 letters, one from mother and one from father. 

• It codes for a specific trait.

• If the trait is dominant we use a capital letter. e.g. Tall (T)

• If the trait is recessive we use a small letter. e.g. Short (t)
