Varied Piglet Markings
This litter of pigs all have the same parents, but some have black and white markings, while two have red and white. It is evidence that animals have varied inherited traits.
Location
Pleasantville, Iowa
Possible Guiding, Compelling and/or Anchoring Questions
- Why are there two pigs in the litter that have red and white markings instead of black and white markings?
- If these piglets have the same parents, why do they look different?
Classroom Suggestions
- Lead students to understand that traits are passed along from parents AND grandparents, and that variation exists, even within the same litter.
