Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the mechanisms of integration?Key mechanisms include genetic correlation, developmental pathways, and functional dependencies
2. What does phenotypic integration mean?It means that the different parts of an animal’s body are connected and change together, not just on their own.
3. Why do animals’ body parts work together?Because traits can be linked by shared genes, shared development, or because they need to work together to do a job, like hunting or eating.

Genetic Correlation: The tendency for genes that influence multiple traits to be inherited together, linking those traits.
Developmental Constraint: Limitations on the range of possible phenotypes imposed by the underlying developmental processes.
Quantitative Genetics: The study of the inheritance of traits that vary continuously and are influenced by multiple genes and environmental factors.
