Heredity, Reproduction, and Punnett Square Check
 Complete the following questions. Use your notes if you need assistance. You can submit this as many times as you need, but it must be done within the class period.

It makes sexual reproduction possible

It allows bacteria to reproduce asexually.

Select ALL of the follwoing that are true about Sexual Reproduction.

offspring are unique and look different from parents
