Which gene is dominant? Why? What is the genotype of your offspring? You then cross the offspring to each other. What ratio do you expect? Why? You count 1000 plants and look at their flowers.

#2 a) If sex and eye colored were viewed as two different phenotypes with male being dominant over female (or vice versa), then Mendelian ratios of a dihybrid cross may explain the ratios that Morgan got. Here is some hypothetical data based on the ratios gotten by Morgan and the expected Mendelian ratios for a dihybrid F1 cross. Perform a Chi-square test (separate scrap paper) with the null hypothesis being that the "Morgan observed ratios" are within chance from the Mendelian ratios. State whether the Chi-square test supports or rejects the null hypothesis and explain. (Be sure to include the X2 value, degrees of freedom, critical value.) Hint: what did Morgan discover?

O e. 1/8 QUESTION 3 In Mendel's pea plants, round shape (R) is dominant to wrinkled shape (r), and yellow color (Y) is dominant to green color (y). The alleles for seed shape and seed color sort independently. In the parental generation, Mendel crossed a true-breeding round, yellow-seeded plant with a true-breeding wrinkled, green-seeded plant to create an F1 generation. He then crossed the F1 offspring to eachother. What type of cross is this considered?

0 + + O O Coat color in cats is determined by genes at several different loci. At one locus on the X chromosome, one allele (X` ) encodes black fur and another allele (X) encodes orange fur. Females can be black (X X ), orange (X X ), or a mixture of orange and black called tortoiseshell (X X ). Males are either black (XY) or orange (XY). O Bill has a female tortoiseshell cat named Patches. One night, Patches escapes from Bill's house, spends the night out, and mates with a stray male. Patches later gives birth to the following kittens: one orange male, one black male, two tortoiseshell females, and one orange female. What are the genotypes of Patches, the stray male, and the kittens?
