---

Use the following traits to determine the genotype and phenotypes of your child.

Trait/Gene(s)	Alleles
Finger Length Finger Length (F or f)	F = normal fingers f = long fingers
Height* Height 1 (H1 or h1) Height 2 (H2 or h2)	H1H1H2H2 = very short H1H1H2h2 = somewhat short H1H1h2h2 = average H1h1h2h2 = somewhat tall h1h1h2h2 = very tall
Communication Skills* Communication Skills (T or t)	T = talkative t = quiet
Math Ability* Math 1 (M1 or m1) Math 2 (M2 or m2)	M1M1M2M2 or M1M1M2m2 = high M1M1m2m2 = average M1m1m2m2 or m1m1m2m2 = low
Hypercholesterolemia* Hypercholesterolemia 1 (C1 or c1) Hypercholesterolemia 2 (C2 or c2)	C1C1C2C2 or C1C1C2c2 = very likely C1C1c2c2 = likely C1c1c2c2 or c1c1c2c2 = not very likely
Stamina* Stamina (S or s)	S = high s = low

Vision Vision (V or v)	V = near sighted v = normal vision
Dimples Dimples (I or i)	I = dimples i = no dimples

* Note that these traits may also be affected by the child's environment
