Lesson 2 : Lab

Time Required: 150 minutes

Create two alien families in order to explore both the processes and outcomes of genetic variation. One alien family will reproduce sexually and one will reproduce asexually to model both reproductive ways. Students then will communicate the difference between asexual and sexual reproduction.

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.]
