Reflection: Developing a Conceptual Understanding Meiosis Simulation Lab (Day #2 of 3) - Section 3: Instructional Input/Student Activities


The student work featured here (beginning on p. 7) shows how the chromosomes appear at the end of Meiosis II. The big idea is that 1 diploid cell undergoes one round of duplication and two subsequent rounds of division that results in 4 haploid cells. This reduction is necessary to set up fertilization (see p.8) and imagine that one chromosome is red/blue and the other is yellow/green representing the maternal and paternal contributions to the new offspring.

Additionally, this student's work represents the genetic recombination of two chromosomes that participated in crossing over during Prophase I.  

Well done, young man!

Meiosis Simulation Lab (Day #2 of 3)

Unit 4: 3) Genetics ("Identity & Change")
Lesson 3 of 10

Objective: Students will be able to describe how meiosis can create haploid gametes that are different from all other gametes. In other words, with the exception of identical twins, no two siblings are identical. Furthermore, no child is identical to either or both parents.

Big Idea: Meiosis is the process that produces unique sex cells that eventually leads to the creation of genetically unique offspring.
