This trait can be determined by feeling the tendons of the wrist when clenching the hand tightly. A) Hitch-hikers thumb B.) Bent-little finger C.) Long Palmar Muscle

Non-tasters have two copies of the non-tasting allele. (T/F)?

This condition is known as "distal hyper-extensibility". A.) Bent Little Finger B.) Hitch-hiker's thumb C.) Long Palmar Muscle D. Mid- Digital Hair

(T/F) In the bugsville activity, actual response to selection matched close enough/ exactly to the predictive response.

To about 75% of us, the chemical PTC tastes very bitter. What does PTC stands for?

Tasting is dominant, meaning that if you have at least one copy of the tasting version of the gene, you can taste PTC. True or False?

Hitch-hiker's thumb is a dominant or receesive trait?

It is caused by a single gene located on the X-chromosome. This gene codes for a protein in the eye that detects certain colors of light. When this gene is defective, the eye cannot differentiate between red and green.

They are small, concentrated spots of a skin pigment called melanin. Most fair-skinned, red-haired people have them.

In bugsville activity, the red dots represent ladybugs. Large dots are adults while small dots are_____

In the bugsville activity, what did you set out/ estimate to determine?

Widow's peak is likely controlled by environment rather than the genes. But while hairline shape tends to run in families, its pattern of inheritance is usually unpredictable, suggesting that multiple genes are involved. (T/F)
