- A true-breeding plant expressing a dominant phenotype is crossed with a true-breeding plant expressing a recessive phenotype. There were 36 offspring produced. Two of those offspring were crossed with each other, and 42 offspring were produced. Which generations will have or will possibly have individuals that are heterozygous? F2 only F1 and F2 P and F2 F1 onlyA cross was made between a plant that has blue flowers and purple seeds and a plant with white flowers and green seeds. The F1 generation was then allowed to self-fertilize. The following data were obtained. F1 Generation: All offspring have blue flowers with purple seeds. F2 Generation: 208 blue flowers, purple seeds 13 blue flowers, green seeds 19 White flowers, purple seeds 60 white flowers, green seeds Total: 300 The scientist needs to test if the two genes segregate independently and has formulated the null-hypothesis that there is no significant difference between the observed and expected data. What are the degrees of freedom for this experiment?What are the phenotypes? What is the ratio of those phenotypes?
