If the following cross occurred AAbb x aaBB, what is the probability of getting an offspring that is heterozygous for both alleles? Select one

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 B C D E F 20 15 10 20 30 G 20 20 20 Using the map, what is the expected frequency of homozygous recessives (cd/cd) from a testcross of Cd/cD X cd/cd? . a. 20% b. 10% c. 5% d. this progeny class will not be formed e. none of the above

In mice, black fur (B) is dominant over brown fur (b). Two black mice had only black offspring. Which of the following offspring genotypes could result from the parental cross? Select all that apply. A. BB B. Bb C. bb
