Concept explainers
A three-gene system of additive genes (A, B, and C) controls plant height. Each gene has two alleles (A and a, B and b, and C and c). There is dominance among the alleles of each gene, with alleles A, B, and C dominant over a, b and c. Under this scheme, the dominant genotype for a gene contributes

- Please solve this problem using the test cross branch diagram without a punnet square.arrow_forwardThree gene pairs located on separate autosomes determine flower color and shape as well as plant height. The first pair exhibits incomplete dominance, where the color can be red, pink (the heterozygote), or white. The second pair leads to personate (dominant) or peloric (recessive) flower shape, while the third gene pair produces either the dominant tall trait or the recessive dwarf trait. Homozygous plants that are red, personate, and tall are crossed to those that are white, peloric, and dwarf. Determine the F1 genotype(s) and phenotype(s). If the F1 plants are interbred, what proportion of the offspring will exhibit the same phenotype as the F1 plants?arrow_forwardWhen traits show complete dominance, the genotype can be revealed by a test cross. In the example of tall and dwarf plants (Figure) why is it necessary to use the dwarf parent? In general, why is it necessary to use a parent that is homozygous recessive?arrow_forward
- In corn plants, a dominant allele (1) inhibits the expression of kernel color, while the recessive allele (1) promotes the expression of kernel color when homozygous. Another dominant allele, (P), causes purple kernel color, while the homozygous recessive genotype (pp) causes red kernels. Assuming that these alleles assort independently, predict the phenotypic ratio of the offspring if two plants dihybrid for these characteristics are crossed.arrow_forwardConsider the following hypothetical gene a plant.Gene T produces a protein that impacts stem length.There are two alleles for gene T, T which produces long stems and t which results in short stems. Assume that gene T displays complete dominance, what would be the genotypes (written as two letters-your answer will be case sensitive) that correspond to- homozygous dominant, homozygous recessive and heterozygous. and the phenotypes (what trait will be observed in the plant) for each of the genotypes.arrow_forwardA new kind of tulip is produced that develops only purple or pink flowers. Assume that flower color is controlled by a single-gene locus and that the purple allele (C) is dominant to the pink allele (c). A random sample of 1000 tulips from a large cultivated field yields 847 purple flowers (out of which 476 are heterozygous) and 153 pink flowers. If p = frequency of C allele and q = frequency of the c allele. Calculate p and q. A. p = 0.4 q = 0.6 B. p = 0.61 q = 0.39 C. p = 0.847 q = 0.153 D. p = 0.82 q = 0.18arrow_forward
- Y = yellow, y = green; R = round seed, r = wrinkled seed %3D An individual has the genotype YYRR and has offspring with an individual with the genotype yyrr. If the genes are both expressed with complete dominance, then what phenotype will all the offspring have? Yellow and Wrinkled Yellow and Round Green and Round Green and Wrinkledarrow_forwardA plant is heterozygous for yellow flowers and hairy leaves. This is self-pollinated. What are the expected genotype, phenotype, phenotypic ratio and genotypic ratio in F1? (Red and smooth characters are recessive)arrow_forwardConsider the following hypothetical gene a plant. Gene T produces a protein that impacts stem length. There are two alleles for gene T, T which produces long stems and t which results in short stems. If gene T displays incomplete dominance, which of the following genotypes above would have a different phenotype? and What would the phenotype be for this genotype?arrow_forward
- a. 1 dominant allele will contribute 120/10 = 12 cm to the base height of the plant.b. The height of the parent plant 1 Genotype of the parent plant 1 – D1D1D2D2D3D3d4d4d5d5 The height of the parent plant 2 Genotype of the parent plant 2 – d1d1d2d2d3d3D4D4D5D5Contributing alleles – D4D4D5D5. The height of the plant without any contributing alleles would be 80 cm. The plant with genotype d1d1d2d2d3d3D4D4D5D5 has 4 contributing allele each of which contributes 12 cm to the base. Hence, the height of the plant with genotype d1d1d2d2d3d3D4D4D5D5 would be 80 + 12 + 12 + 12 + 12 = 128 cm. c.

The homozygous dominant weighs 200 g while the homozygous recessive weighs 80 g. Assume that the alleles have equal contribution and have cumulative effects. The F1 and F2 of the two parents below were studied. Parent 1 - D1D1D2D2D3D3d4d4 x Parent 2 - d1d1d2d2d3d3D4D4 Compute for the contribution of the dominant allele. Compute for the fruit weight of parental 1 and parental 2.arrow_forwardWhite fruit color in summer squash is dependent on a dominant gene (W) and colored fruit to the recessive gene (w). In the presence of ww a dominant gene produces yellow color, but when D is not present, the color is green. Give the F2 phenotypes and the proportions expected from crossing (show the diagram) a white-fruited (WWDD) with a green-fruited (wwdd) plant.arrow_forward
