Question

5. In Mendel's experiments, the pod color gene and the seed shape gene were located on different chromosomes (in other words, they were not linked. They assort independently). Green pods (G) are dominant over yellow pods (g) and tall stems (T) are dominant over dwarf stems (t). You are given two true breeding plants (homozygous at both genes). In the parental (P) generation, one parent has green pods and dwarf stems and the second parent has yellow pods and tall stems. a. Read the description above. What are the genotype(s) of the two parent plants described above? The Genotypes are Gott and ggTT. b. What are the genotype(s) and phenotype(s) of the first generation (F1) offspring? (You may want to draw a Punnett square to check your answer. Remember that you are dealing with two genes.) Genotypes are Gt and RT. The phenotype is Green pods with tall stems. 6. cross. If you cross an F1 from question 5 above with another F1 from question 5, this is a dihybrid a. Do the dihybrid cross to determine the genotype(s) of the potential F2 offspring if two F1 plants were crossed. You must include your Punnett square, which can be hand-drawn. Remember that you are dealing with two genes. b. What are the possible phenotype(s) of the second generation (F2) offspring? How many of each phenotype is possible? What is the ratio of the phenotypes in the offspring
