Worksheet #2 – Introduction to Heredity
Directions: During this activity you will analyze some pictures of humans and look for similar and different
characteristics. You will learn some basic information about genetics and heredity, and see some examples of
characteristics that are passed from one generation to the next.
1.
Look at the pictures below carefully. There are three sets of parents and their children pictured.
PARENTS A
CHILD 1
PARENTS B
CHILD 2
PARENTS C
CHILDREN 3
CHILD 4
2. Look at Parent A. What are some traits (characteristics) you can observe about them? Make at least three
detailed observations.

9. What child or children do you think belong to Parents C?
10. What about this child or children makes you think that they are related to Parents C?

father?
12. What are three variations (differences) you notice between the humans pictured?
13. Name 3 human physical traits that show a lot of variations in different people throughout the world.
14. Do other species have variations in their traits? Give a specific example of another species and name a
trait in which they show a lot of variations in that species.
