Patterns of Traits are passed on from parents to offspring.
Understanding these patterns is crucial to our understanding of how traits are passed on and to predicting disease risk in family members.
[CER] What pattern of similarities in traits between parents and offspring, and between siblings, provides evidence that variations of traits are inherited?

/ Ii / Investigate
1. Puppy Parents - analyze the patterns of similarities and differences in the traits of four different adult dogs to determine the possible puppy parents.
3. Creature Features - investigate how simple inherited traits are passed down from parents to their offspring and then to the next generation. 4. Gene Combo - investigate how tossing coins help explain how organisms inherit genes from their parents. 5. Mendel, First Geneticist - investigate Gregor Mendel and how he discovered the basis of heredity by breeding pea plants. 6. Analyzing Genetic Data - Do your results agree with Mendel's model for inheritance? 7. Show me the Genes! - discover the role chromosomes play in the inheritance of genes. 8. Breeding Critters - More Traits - investigate some patterns of inheritance other than the one discovered by Mendel. 9. Patterns in Pedigrees - investigate how you can use pedigrees to study human traits. 10. DNA Extraction - investigate how you can observe DNA extracted from a strawberry. |

During this lesson you will learn more about how characteristics of one generation are related to the previous generation.
✎Notes:
- Many characteristics of organisms are inherited from their parents.
- Other characteristics result from individuals’ interactions with the environment, which can range from diet to learning. Many characteristics involve both inheritance and environment.

Hemophilia is an inherited bleeding disorder. People with hemophilia can't stop bleeding because they don't have enough clotting factor in their blood. Clotting factors are needed for blood to clot and prevent excessive bleeding. Using the pedigree chart available to describe 2 or more patterns about how the hemophilia trait is passed on from parent to offspring. EXPERT [+5 points]
Why do some traits between parents and offspring, and between siblings, provide evidence that inherited traits can vary? Use a specific example from your own family or experience. |

Using your own family create your own pedigree chart depicting the similarities and differences of a particular trait (eye color, hair color, height etc.) between your family members to provide evidence that traits are inherited and that traits that are inherited can vary. Discuss several patterns you see and make some predictions for your own offspring in the future. |

Brown-headed cowbirds are small birds found throughout North American grasslands and along edges of forests. For food, the brown-headed cowbirds rely on grazing animals to uncover insects and seeds.
When a female brown-headed cowbird sees eggs in the nest of another bird, she lays her own egg in the nest. She usually chooses nests with eggs that are smaller than hers. The other bird species then raises the brown-headed cowbird hatchling. The brown-headed cowbird hatchling grows quickly and is larger than the other hatchlings in the nest. |
