- A strain of plants has a mean height of 24 cm. A second strain ofthe same species from a different geographical region also has a mean height of 24 cm. When plants from the two strains arecrossed together, the F1 plants are the same height as the parentplants. However, the F2 generation shows a wide range ofheights; the majority are like the P1 and F1 plants, but approximately4 of 1000 are only 12 cm high, and about 4 of 1000 are36 cm high. Question: What mode of inheritance is occurring here?Seed weight in a particular plant species is determined by pairs of alleles attwo loci (a+ a− and b+ b−) that are additive and equal in their effects. Plantswith genotype a− a− b− b− have seeds that average 1 g in weight, whereasplants with genotype a+ a+ b+ b+ have seeds that average 3.4 g in weight. Aplant with genotype a− a− b− b− is crossed with a plant of genotype a+ a+ b+b+.a. What is the predicted weight of seeds from the F1 progeny of this cross?b. If the F1 plants are intercrossed, what are the expected seed weights andproportions of the F2 plants?A series of experiments shows that oil content in a diploid grain is influenced by four genes (a through d) with additive alleles. The highest-producing strain has 30% oil content; the lowest has 0%. A plant of unknown genotype has an oil content of 22.5%. What is a possible genotype for this plant (+ - additive alleles)?

Determine the parentals, SCOI, SCO II, and DCO products and the estimated number of individuals for each. y-------------sh-- 18% 28%A corn geneticist wants to obtain a corn plant that hasthe three dominant phenotypes: anthocyanin (A), longtassels (L), and dwarf plant (D). In her collection ofpure lines, the only lines that bear these alleles are AALL dd and aa ll DD. She also has the fully recessive lineaa ll dd. She decides to intercross the first two and testcross the resulting hybrid to obtain in the progeny aplant of the desired phenotype (which would have to beAa Ll Dd in this case). She knows that the three genesare linked in the order written, that the distance between the A/a and the L/l loci is 16 m.u., and that thedistance between the L/l and the D/d loci is 24 m.u.a. Draw a diagram of the chromosomes of the parents,the hybrid, and the tester.b. Draw a diagram of the crossover(s) necessary toproduce the desired genotype.c. What percentage of the testcross progeny will be ofthe phenotype that she needs?d. What assumptions did you make (if any)?Fine spines (s), smooth fruit (tu), and uniform fruit color (u) are three recessive traits in cucumbers. A cucumber plant heterozygous for all three traits is used in a test cross, and the following progeny are produced from this test cross.

Theoffspring are wild-type, 721; black purple, 751; gray purple, 49;black red, 45. What is the recombination frequency betweenthese genes for body color and eye color?
