A certain species of morning glories produces flowers that are blue, red, or purple. Two pure-breeding purple lines are crossed and produce F1 progeny that all make blue flowers. The F1 are allowed to self and produce 320 F2 progeny with the following distribution: 185 blue, 115 purple, and 20 red. Which the following is NOT consistent with this information? A) Red-flowering plants are homozygous recessive for both genes. B) The pure-breeding parental parents are homozygous recessive for mutations in two different genes. C) Dominant gene interaction appears to result in a 9:6:1 ratio. D) Blue-flowering plants are either A_bb or aaB_. E) Analysis of the F1 and F2 progeny phenotypes suggests epistasis.

In some plants, a true-breeding, red-flowered variety gives all pink flowers when crossed with a white-flowered strain: RR (red) X rr (white) = Rr (pink). Flower position in this plant may either be axial (dominant) or terminal (recessive). What will be the phenotypic ratios of the F1 generation resulting from the following cross: axial-red (true-breeding) X terminal-white? What will the phenotypic ratios of the F2 be? SHOW ALL WORK
A type of tomato (Solanum lycopersicum) produces fruit in three possible colors: red, orange, and green. You cross a true-breeding red-fruited plant with a true-breeding green-fruited plant, and all the F1 offspring are red. You intercross the red F1s, and the resulting F2 generation consists of 61 red-, 13 orange-, and 6 green-fruited plants. a) Assign the phenotypes to a modified 9:3:3:1 ratio (do not just calculate the actual ratio of the phenotypes). Show your work.
In a certain type of pea plant, the gene for yellow color (Y) is dominant to the gene for green color (y), and the gene for round shape (R) is dominant to the gene for wrinkled shape (r). If a homozygous dominant plant is mated with a homozygous recessive plant (P-gen), what proportion in the F2 generation will be homozygous recessive? a) 1/4 b) 1/16 c) 3/4 d) 3/8
Two pure-breeding lines of petunia plants are crossed. Line 1 plants grow to a height of 54 cm, and Line 2 plants grow to a height of 18 cm. Petunia plant height is controlled by three genes, A, B and C. Line 1 has the genotype A₁A₁B₁B₁C₁C₁, and line 2 has the genotype A2A2B₂B₂C₂C₂. Assume that genotype alone determines plant height under ideal growth conditions and that the alleles of the three genes are additive. If the F1 plants are self crossed, what is the expected proportion of F2 plants with the genotype A₁A₁B₁B₁C₁C₁ 1/8 1/32 1/16 1/4 1/64
In pea plants, yellow seeds (Y) are dominant to green seeds (y) and round seeds (R) are dominant to wrinkled seeds (). The genes for seed color and seed shape are on different chromosomes. Two true-breeding parents, one with yellow round peas and the other with green wrinkled peas, are crossed to produce a hybrid (heterozygous) F₁. Two F₁ individuals are crossed to give an F2; this is depicted in the Punnett square below. Place the correct genotypes in the Punnett square and the place the correct phenotypic ratios next to their appropriate phenotype on the right.

Assume that the trihybrid cross AABBrr x aabbRR is made in a plant species. Assume that A and B are dominant alleles, but there is no dominance effect of alleles at the R locus. a) How many different gametes are possible in the F1generation? What are the genotypes of these gametes? b) What is the probability of the parental aabbRR genotype in the F2 progeny? c) What proportion of the F2 progeny would be expected to be homozygous for all three genes?
In corn, seedling color is determined by genes at two loci (C/c and D/d). Suppose that you cross a pure-breeding green seedling with a pure-breeding yellow seedling and obtain only green seedlings in the F1 generation. You then cross two of the F1 seedlings and obtain the following progeny for the F2 generation: 138 green seedlings, 33 virescent-white seedlings, and 10 yellow seedlings. What form of epistasis would explain these data?
Three fruit shapes are recognized in the summer squash (Cucurbita pepo): disk-shaped, elongated, and sphere shaped. A pure disk-shaped variety was crossed to a pure elongated variety. The F1 were all disk-shaped. Among 80 F2 there were 30 sphere-shaped, 5 elongated, and 45 disk-shaped. Keeping in mind this gene interaction, what phenotypic proportions are expected in the progeny of the sphere-shaped in F2 when crossed at random?
In sesame plants, the one-pod condition (P) is dominant to the three-pod condition (p), and normal leaf (L) is dominant to wrinkled leaf (l). Pod type and leaf type are inherited independently.

A particular flower can be blue, red, or white. A pure-breeding red-flowered plant is crossed with a pure-breeding white-flowered one. The F 1 are then crossed to produce an F 2 generation. Which of the following phenotypic ratios in the F 2 indicate that flower color in these two strains is controlled by two genes? A)2:1 B)3:1 C)1:2:1 D)9:3:4
In tomato plants, tall vine (D) is dominant over dwarf vine (d) and round fruit (O) is dominant over oval-shaped fruit (o). Two tall, round-fruit shape plants (plants 1 and 2) are crossed with dwarf, oval-shape fruit plants. The results are as follows: i) Why is there a difference in the proportionate number of plants in each phenotypic class of the offspring resulting from test crosses of plants 1 and 2? (ii) Calculate the recombination frequency between the genes D/d and O/o in tomatoes. (iii) Draw a chromosome map for these genes. (Use underscore (_) to draw the line for the map)
