Mendel discovered that the allele for green seed pods (G) is dominant to the allele for yellow seed pods (g). He crossed true-breeding (homozygous) parental plants with green (GG) and yellow (gg) seed pods to produce an F1 generation, all of which were heterozygous (Gg) with green seed pods. He then crossed two of these F1 plants to produce an F2 generation. Drag the genotypes and phenotypes from the left to correctly complete the Punnett square for the F2 generation. Drag only blue labels to blue targets and pink labels to pink targets. Labels may be used more than once. a. GG b. Green c. Gg d. green e. Gg f. green g. gg h. yellow

Mendel found that one of his favorite plants was heterozygous for pod color. G represents the dominant yellow color, and g represents the recessive green color (same as Q.1). In order for the plant to have the recessive pod color, what would the genotype have to be?

Mendel crossed yellow-seeded and green-seeded pea plants and then allowed the offspring to self-pollinate to produce an F2 generation. The results were as follows: 6022 yellow and 2001 green (8023 total). The allele for green seeds has what relationship to the allele for yellow seeds? A. co-dominant. B. dominant C. semi-dominant D. incompletely dominant E. recessive

In pea plants, the allele for green pea pods (G) is dominant, and the allele for yellow pea pods (g) is recessive. You breed a homozygous recessive pea plant (gg; true-breeding for yellow pods) with a pea plant that has green pods. You don't know if the plant with green pods is homozygous dominant or heterozygous dominant (it could be Gg or GG): If the green pod plant is homozygous dominant, what genotypes and phenotypes do you expect to see in the offspring, and at what ratios? (1 pt) If the green pod plant is heterozygous dominant, what genotypes and phenotypes do you expect to see in the offspring, and at what ratios? (1 pt)
