Determine the coefficient of coincidence and the interference for these three loci.

Tomato Plants In tomato plants, round fruit (R) is dominant to oval fruit (r). Pure breeding plants with red and round fruit (FFRR) were crossed to pure breeding plants with yellow and oval fruit (ffrr). The red and round F1 progeny were then testcrossed to plants that were homozygous recessive for both genes (ffrr) with the following results: Phenotypes Number of Offspring Red and round 2 255 Red and oval 290 Yellow and round 310 Yellow and oval 2 145 Part A: Record the phenotypes and the phenotype ratio in lowest terms. Part B: Convert the expected phenotypic ratio from Part A into the expected probability for each of the four phenotypes and record them in the table below. Calculate the probability for each of the four phenotypes observed in the cross from the data presented at the beginning of the question by dividing the number of progeny in each class by the total number of progeny and record these in the table below. (Probability = Number of Progeny in Phenotype…

After a cross between two corn plants, the F₁ plants all had a dwarf mutant phenotype. The F2 consisted of 1,207 dwarf plants and 401 tall plants. Identify the phenotypes and genotypes of the two parents. O d/d (dwarf), D+/d (tall) D/D (dwarf), d+/d+ (tall) D/D (dwarf), D+/D+ (tall) d/d (dwarf), d+/d+ (tall)

Pure-breeding parental strains of corn with the purple, smooth and yellow, wrinkled phenotypes were crossed to produce an F1 generation, which were then crossed to produce the F2 generation. Complete the diagram showing the results of the cross below. (I included an enlarged picture of the corn as well)
