2. How many of the 400 cats with full color are likely to be heterozygous?

You are studying two new traits that control tomato color (red v. albino) and shape (round v. long). You cross a red and round tomato plant with one displaying albino and long. The resulting F1 are all red and round. The F2 have the following phenotypes (8 points)

834 round, red

250 round, albino

272 long, red

80    long, albino

1. Which of these characteristics are dominant?
2. What are the most likely genotypes of the F2?
3. What is the mode of inheritance? (Use words like, autosomal, sex-linked, dominant, epistatic, incomplete dominant, etc.)

d. Test your hypothesis using the Chi-square statistic.
