Draw a Punnett square to determine the possible genotypes of offspring based on the parents' genotypes:
1. Cross a heterozygous parent with a homozygous dominant parent for eye color. Let B stand for dominant brown eyes and b stand for recessive blue eyes. What percentage of offspring will have blue eyes?
2. Cross a homozygous dominant parent with a homozygous recessive parent for the widow's peak trait. Let W stand for widow's peak (dominant) and w stand for no widow's peak (recessive). What percentage of offspring will have widow's peaks?
Continue Determination of Genotypes from Phenotypes in Humans Lab (Traits Lab) Due by end of class today for 20 points
Learning Objective: I can determine my own possible genotypes from my phenotypes.

TIPS TO HELP YOU WITH TRAITS LAB:
-cilantro tasting trait is not yet determined to be dominant or recessive, so do not include it in your list of traits in the analysis questions.
-remember that hair texture, inter-eye distance, and lip protrusion are all traits that are neither dominant or recessive, they are incompletely dominant traits
-for #8 look at page 1 in the second paragraph where we highlighted together
