Chapter 12, Problem 1A
Japanese four o’clocks that are red and tall are crossed to white short ones, producing an F1 that is pink and tall. If these genes assort independently, and the F1 is self-crossed, what would you predict for the ratio of F2
a. 3 red tall:1 white short
b. 1 red tall:2 pink short: 1 white short
c. 3 pink tall:6 red tall:3 white tall:1 pink short:2 red short:1 white short

A cross occurs between a black homozygous mouse and a white homozygous mouse. They produce gray offspring.
Referring to the mouse scenario noted above, what is the percentage phenotypic probability if we cross two gray mice from F1 generation?
a. 100% black
b.75% gray; 25% white
c. 25% black ; 50% gray , 25% white
d. 50% black; 50% white
In four-o'clocks, the allele for red flowers is incompletely dominant over the allele for white flowers, so all heterozygotes have pink flowers. If you cross a white flower with a pink flower, what is the phenotypic ratio of the F1 generation (i.e., the offspring that are produced)?
a.
1 red: 2 pink: 1 white
b.
0 red: 2 pink: 2 white
c.
1 red: 0 pink: 3 white
d.
1 red: 1 pink: 2 white
e.
0 red: 4 pink: 0 white
A cross occurs between a black homozygous mouse and a white homozygous mouse. They produce gray offspring. Respond to the question based upon this scenario.
What are the percentage probabilities for the genotype and phenotype of the offspring?
a. 100% black; 100% Bb
b. 100% gray; 100% bb
c. 100% white; 75% Bb, 25% bb
d. 100% gray; 100% Bb
