Be able to do Punnett Square problems for example: take a heterozygous person with a widow’s peak (dominant
allele) with a person without a widow’s peak.
a. What is the percent probability of children with a widow’s peak?___________
b. What is the percent probability of children without a widow’s peak?___________
c. What is the percent probability of homozygous dominant genotype?_________
d. What is the percent probability of heterozygous genotype?_________
e. What is the percent probability of homozygous recessive genotype?__________
Do a Punnett Square when one parent has blood type AB and the other parent is heterozygous for type A blood.

Draw a pedigree chart filling in as much as you can from the information. (Fill in half if you know it is at least
half.)
a. Arnold is married to Brenda. They have three kids (Charlie, Dora (the Explorer) and Elvis)
b. Charlie marries Gloria and they have two kids (Henry and Isaac).
c. Dora (the Explorer) never gets married because she is too busy exploring.
d. Elvis marries Pricilla and they have two kids. (Julie and Krista)
e. Krista has a condition that causes her nose to bleed when she tilts her head back too far. (We will
pretend this is a recessive genetic disorder.)
f. Brenda and Gloria also have this condition.
g. Please draw the pedigree chart and fill in all the information you can.
