1. For the following: Using the table function, diagram and complete the genotypes of the parents and offspring within a Punnett Square. State the phenotype results (as percentages) of the offspring separately. Look at my example on the module to see how the questions should be answered! Also, if stated, place the male genotype on the top.
A. In humans, straight toes (S) is dominant over curled toes (s). What would be the result of a cross between a heterozygous male and a heterozygous female?
B. In peas, tall stems (T) is dominant over short stems (t). What would the result be if a short plant was mated with a homozygous dominant plant.

2. For the next section, please look at the video and the section in your textbook on Sickle Cell anemia (chapter 4). Is the Sickle Cell mutation/allele always negative? Why or why not? Please look at what your textbook says.
