=Genoytypes vs Phenotypes= =in your Family or Future Family=

= = =Genetic Traits= = = == Free earlobes are those that hang below the point of attachment to the head. Attached ear lobes are attached directly to the side of the head. A white forelock is a patch of white hair, usually located at the hairline. Widow's Peak (below) is dominant over no widow's peak hairline.
 * Earlobes:** Free ear lobes (dominant trait) vs. Attached ear lobes (recessive trait)
 * Forelock:** White forelock (dominant trait) vs. No white forelock (recessive trait)

Dimples are natural dents in the face to the right or left of the mouth. If a person has only one dimple, they should be counted as having dimples.Cleft chin is dominant over no cleft. Longer 2nd toe is dominant over 2nd toe shorter than big toe. Tongue-Rolling: Rolling up edges (dominant trait) vs not rolling (recessive)
 * Dimples:** Dimples (dominant trait) vs. No dimples (recessive trait)
 * Thumbs:** Straight thumb (dominant trait) vs. Curved thumb (recessive trait) When viewed from the side as in the illustration below, curved thumbs can be seen as part of a circle.
 * Pinky:** Straight pinky (recessive trait) vs. Bent pinky (dominant trait)
 * Mid-digit hair:** Mid-digit hair (dominant trait) vs. No mid-digit hair (recessive trait)

=Profiling Your Family=

//Using at least 3 generations of their families, students will choose at least 3 genetic traits and create a leafed-out tree.//

== =**CREATING THE LEAVES**= Students will:
 * 1) create a leaf for each member of his/her family,
 * 2) write the three CLASS-chosen genetic traits on each leaf,
 * 3) write the name of the family member on the leaf

=CREATING THE TREE= Students will:
 * 1) draw a tree on a piece of chart paper
 * 2) place your family's leaves on the branches where they belong

Are the Dominant traits actually dominant in TPLC families?**
 * Which branches have more leaf-clusters on them? Why?
