Polygenic is the inheritance pattern of a trait that is controlled by the two or more genes. Each gene may have two or more alleles. The resulting phenotype usually shows a range of value for the trait and mostly governs by additive effects of allele. For example: height, and color.

When you cross true-breeding tall and short tobacco plants you get an F1 that is intermediate in height. When this F1 is self-crossed, it yields an F2 with a continuous distribution of heights. What is the best explanation for these data? a. Height is determined by a single gene with incomplete dominance. b. Height is determined by a single gene with many alleles. c. Height is determined by the additive effects of many genes. d. Height is determined by epistatic genes.

You experiment with the genetics of height in a plant. You cross a homozygous tall (TT) plant with a homozygous short (tt) plant. Describe what the genotype and phenotype of the F1 progeny would look like if the plants exhibited complete dominance. Now describe the expected results if the trait exhibited incomplete dominance. What about the F2 progeny, assuming you crossed the F1 progeny with each other?

True breeding eggplant plants producing deep, purple colored fruit are crossed with true breeding plants producing white fruit. The offspring of this cross all produce lighter, violet fruit. The colors of the fruit are produced by the interactions of the two different alleles. A.Predict the genotype of the F1 plant. B. Predict the expected proportions and genotypes in the F2 generation, if F1 eggplants are crossed.
