Book: Human and Social Biology for CSEC Examinations by Phil Gadd

Topic: Heredity and Variation

Sub-Topic: Monohybrid Inheritance

Instruction:

1. Answer the following questions.

Checkpoint Question

1. Whether you have dimples or not is decided by a single gene with two alleles. The dimple allele D is dominant to the non-dimple allele d. Use this information to help you answer these questions. Create Punnett squares to the show the genetics of your explanations, example: Tom has dimples but Sandy does not. They are expecting a baby.

a) We know exactly what Sandy's dimple alleles are. What are they and how do you know?

b) If the baby does not have dimples, what does this tell us about Tom's dimple alleles?

c) If the baby has got dimples, what does this tell us about Tom's dimple alleles?
