Some inbred strains of the weedy plant arabidopsis thaliana flower early in the growing season, but other strains flower at later times. four different arabdiposis plants (1β4) were crossed, and the resulting progeny were tabulated as follows: mating progeny 1 Γ 2 77 late : 81 early 1 Γ 3 134 late 1 Γ 4 93 late : 32 early 2 Γ 3 111 late 2 Γ 4 65 late : 61 early 3 Γ 4 126 late a. explain the genetic basis for the difference in flowering time. how do you know that among this group of plants, the flowering time trait is influenced by the action of a single gene? which allele is dominant and which recessive? b. ascribe genotypes to the four plants. c. what kinds of progeny would you expect if you allowed plants 1β4 to self-fertilize, and in what ratios?

What is the best conclusion based on this data? the hypothesis was not supported because the data indicated that fertilizing plants does not improve plant growth. the hypothesis was supported; to get the best growth, use 5 milliliters of fertilizer per plant. the hypothesis was not supported; the data indicated that too much fertilizer can inhibit plant growth. the hypothesis was supported; to get the best growth, use 15 milliliters of fertilizer per plant.
