Question

Describe how phenotypes can be used to predict genotypes in a pedigree

Answer 1

Because some phenotypes that are observed are dominant genes, which would help predict what the genes would be. For example, brown eyes (B) are dominant, and blue eyes (b) are recessive. If someone had brown eyes, it could be predicted that their genotype would be BB or Bb. I hope my answer has come to your help. God bless and have a nice day ahead!

Answer 2

Phenotypes can be used to predict the genotypes in a pedigree because phenotypes provide physical evidence of what the genotype may be.

For instance, brown eye colour may infer that the dominant gene is brown (BB) while the recessive gene may be blue eyes(Bb).

What is Phenotype?

Phenotype is the physical attributes of an individual.

This may be the eye colour or hair colour of skin colour.

What is Genotype

Genotype refers to the genetic composition of an individual.

The genetic composition is a set of information contained in the Gene's which is responsible for transferring traits of characteristics from parent to offspring.
