__HS-LS3 Heredity: Inheritance and Variation of Traits (click on a standard to see or add resources)__

HS-LS3-1. Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.

HS-LS3-2. Make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.

HS-LS3-3. __Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.__
