1. For each of the questions listed below, a to e, use the information in Table 1 to create Punnett square to determine the following information: parent genotypes, parent gametes, F1 genotypes and phenotypes.

Table 1: Results of Mendel's Experiments

Trait DOMINANT/recessive
plant height TALL / dwarf
flower colour PURPLE / white
seed shape ROUND / wrinkled
seed colour YELLOW / green

a. a heterozygous tall plant is crossed with a dwarf plant

b. two plants that are heterozygous for purple flowers are crossed

c. a plant that is homozygous for wrinkled seeds is crossed with a plant that is heterozygous for round seeds

2. For Labrador retrievers, black fur colour is dominant over yellow.

a. How would you represent the above information? (notation / let statements)

b. What would be the genotype of a homozygous black dog?

A heterozygous black dog?

c. Could the heterozygous black dog have the same geno as a dog with yellow fur? Explain.

3. For Dalmatian dogs, the spotted condition is dominant over non-spotted.

a. Using a Punnett square, show the results of a cross between two heterozygous parents.

4. Believe it or not, thanks to a recessive genetic condition called myotonia congenita, some members of a goat population actually seem to faint when they are startled. A fainting male is crossed with a non-fainting, heterozygous female. Provide a full genetic solution to determine the phenotypes and genotypes of the offspring of this cross.
