Space probes have
discovered tiny creatures
on the surface of Mars. These tiny creatures are called Martian-Mallow
Mobots. During this
lesson, students will learn about genetic
variation as groups construct Martian-Mallow Mobot offspring.

Students are introduced to the
structure of chromosomes and genes as these concepts are illustrated
utilizing articles of clothing as a model of a chromosome. Students
demonstrate genotypes, phenotypes, and genetic crossings using colored
socks and shirts. This lesson provides an introduction and basis
for understanding Punnett squares. |
