Dihybrid Cross Problem 1: Predicting combinations of alleles in gametes of plants heterozygous for two traits. A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic; s is the allele for the recessive, dented shape characteristic. Y is the allele for the dominant, yellow color characteristic; y is the allele for the recessive, green color characteristic. What will be the distribution of these two alleles in this plant's gametes? A. 50% of gametes are Sy: 50% of gametes are sY B. 25% of gametes are SY; 25% of gametes are Sy: 25% of gametes are sY; 25% of gametes are sy. C. 50% of gametes are sy: 50% of gametes are SY D. 100% of the gametes are SsYy E. 50% of gametes are SsYy: 50% of gametes are SSYY.

Several alleles affect traits of roses, such as plant form and bud shape. Alleles of one gene govern whether a plant will be a climber (dominant) or shrubby (recessive). All F1 offspring from a cross between a true-breeding climber and a shrubby plant are climbers. If an F1 plant is crossed with a shrubby plant, about 50 percent of the offspring will be shrubby; 50 percent will be climbers. Using symbols A and a for the dominant and recessive alleles, make a Punnett- square diagram of the expected genotypes and phenotypes the cross between the F1 offspring and the shrubby plant.

List the gene or genes involved, list and define all allele symbols, and indicate the genotypes of the individuals you are crossing above the Punnett square. Answer questions that ask for a ratio as a ratio and questions that ask for a percent as a percent. In snapdragon plants, the alleles for flower color show incomplete dominance. First show a cross of two parents, one with red flowers and the other with white flowers. Then show a cross of two of the F1 plants to get the F2 generation. Indicate the genotype ratio and phenotype ratio for both the F1 and F2 generations.
