Question
Questions 13 – 15 are associated with the Pedigree shown below:
The pedigree is for a monogenic trait (controlled by a single gene).:
13. Is the trait of interest (filled in shapes) encoded by a dominant allele or a recessive allele? Explain your answer in one or two sentences: (3 points)
14. For the mating within the dashed box in the pedigree, fill out the punnett square above that represents the alleles associated with this cross (Use any letter you want for the alleles, but make the dominant allele a capitol letter and the recessive allele a lower case letter). Label the sides of your punnett square that represent the mother’s alleles and the father’s genes. (4 points)
15. Based on your punnett square, what was the probability (percentage) that an offspring would show the trait highlighted in the pedigree? (1 point)

Label the sides of your punnett square that represent the mother’s alleles and the father’s genes. (4 points)
The punette square can be represented as:
Where A is the dominant allele and a is the recessive allele.
15. Based on your punnett square, what was the probability (percentage) that an offspring would show the trait highlighted in the pedigree? (1 point)
Probability that an offspring would show the trait highlighted in the pedigree is 2/4 or 1/2 = 0.5
