Lesson 3 : Engineer

Time Required: 150 minutes

Use scientific reasoning (via reverse engineering) to create the ideal parent genetic combination that would result in their chosen trait in an offspring.

MS-LS3-2

Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation. [Clarification Statement: Emphasis is on using models such as Punnett squares, diagrams, and simulations to describe the cause and effect relationship of gene transmission from parent(s) to offspring and resulting genetic variation.]
