You are studying three linked genes in snapdragons. The flower color locus is in the center. There are 12.7 cM between the flower color locus and the plant height locus. There are 8.8 cM between the flower color locus and the leaf type locus. The coefficient of coincidence is 0.8. Pure-breeding tall, red-flowered plants with fuzzy leaves were crossed to pure-breeding dwarf, blue-flowered plants with smooth leaves. The F1 were testcrossed. Calculate the proportion of the testcross progeny that are expected to have blue flowers and smooth leaves. Round properly to 4 decimal digits. Answer:

Two groups of geneticists, in California and in Chile, begin work to develop a linkage map of the medfly. They both independently find that the loci for body color (B = black, b = gray) and eye shape (R = round, r = star) are linked 28 m.u. apart. They send strains to each other and perform crosses; a summary of all their findings is shown here:a. Provide a genetic hypothesis that explains the three sets of testcross results. b. Draw the key chromosomal features of meiosis in the F1 from a cross of the Californian and Chilean lines.
In a mapping cross, you determine that the recombination frequency between: loci Q and P is 9% loci Q and Lis 13%. If locus Q is in between loci P and L, then the recombination frequency between P and L should be approximately: 65%. 4%. 22% 11%. 13%
A three point testcross is carried out between three linked genes. The resulting nonrecombinant progeny are d+b+k+ and dbk and the double-crossover progeny are dbk+ and d+b+k. Which is the middle locus? Show all your work. Show all possible progeny.

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 Compare the expected probabilities of each phenotype to the observed probabilities. Are the gene for fruit colour and the gene for fruit shape assorting independently? Explain.

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. Compare the expected probabilities of each phenotype to the observed probabilities. Are the gene for fruit colour and…
Genes a and b are 21 m.u. apart when happed in a highly inbred strain 1 of corn and 21 m.u. apart when mapped in highly inbred strain 2. But when the distance is mapped by testcrossing the F1 progeny of a cross between strains 1 and 2, the genes are only 1.5 m.u. apart. What arrangements of genes a and b and any potential rearrangement breakpoints could explain these results?

the heights of two true breeding strains of maize were both 1.75m and when crossed the F1 height was also 1.75m. Selfing the F1 produced an F2 with a range of heights from 1.59 to 1.91m. Out of the F2 of 451 plants there were 25 of the tallest. If the F1 was test-crossed, how many phenotypes would you observe?
You have determined that the gene order for three linked genes being studied is A B C. The number of recombinants resulting from crossover between genes A and BC are 44 and 48, respectively, while the double-crossover progeny total 4 and 6. What is the recombination frequency between genes A and B if the total progeny from the cross is 1000? Show all of your work.
In corn, a colored aleurone is due to the presence of an R allele; r/r is colorless. Another gene controls the color of the plant, with g/g being yellow and G_being green.
