Using the forked-line, or branch diagram, method, determine the genotypic and
HINT: This problem asks you to use the forked-line method to determine the outcome of a number of trihybrid crosses. The key to its solution is to realize that in using the forked-line method, you must consider each gene pair separately. For example, in this problem, first predict the outcome of each cross for the A/a genes, then for the B/b genes, and finally, for the C/c genes. Then you are prepared to pursue the outcome of each cross using the forked-line method.

- A series of three-point testcrosses is made to determine the genetic map order of seven linked allele pairs: A/a, B/b, G/g, H/h, Q/q, R/r, and Y/y.From each cross between a triply heterozygous parent listed below, two recombinant classes were noticed as the least frequent among all 8 progeny classes, and are listed at the right in the table. A. For each testcross write the genotype of the F1 heterozygous parent. F1 Parental Phenotype Least frequent F2 Phenotype 1.AHB&ahb AHb & ahB 2.RYh&ryH RYH & ryh 3.BhY&bHy Bhy & bHY 4.qYB&Qyb qYb & QyB 5.AbQ&aBq Abq & aBQ 6.ghR&GHr ghr & GHR B.

- In the tomato, yellow flowers (Y) is dominant to white flowers (y). A true-breeding yellow flowered strain is crossed with a true-breeding white flowered strain.A. If the F1 generation is self crossed, what will be the genotypes and phenotypes of the progeny and in what portions are they expected? B. If an F1 plant were crossed with a plant from true-breeding white flowered strain, what will be the genotypes and phenotypes of the progeny and in what portions are they expected?arrow_forwardIndividuals of genotype AaBb were mated to individuals of genotype aabb. One thousand offspring were counted, with the following results: 474 Aabb, 480 aaBb, 20 AaBb, and 26 aabb. What type of cross is it? Are these loci linked? What are the two parental classes and the two recombinant classes of offspring? What is the percentage of recombination between these two loci? How many map units apart are they?arrow_forwardWhat two essential criteria must be met in order to execute a successful mapping cross?arrow_forward

What are the possible maternal and paternal genotypes of the F1 gametes of the corn monohybrid cross described above? What is the genotype of the parents of the corn dihybrid cross described above? What are the phenotypes of the parents of the corn dihybrid cross described above? What are the possible genotypes of the parent gametes of the corn dihybrid cross described above? What is the genotype of the F1 generation of the corn dihybrid cross described above? What is the phenotype of the F1 generation of the corn dihybrid cross described above? What are the possible maternal and paternal genotypes of the F1 gametes of the corn dihybrid cross described above?arrow_forwardWhat genotypes would be expected for the offspring from the following matings? What are the phenotypic ratios for each cross? Explain how you came up with this ratio?arrow_forwardSummer squash exist in long, spherical, or disk shapes. When atrue-breeding long-shaped strain was crossed to a true-breedingdisk-shaped strain, all of the F1 offspring were disk-shaped. Whenthe F1 offspring were allowed to self-fertilize, the F2 generationconsisted of a ratio of 9 disk-shaped to 6 round-shaped to 1 longshaped. Assuming the shape of summer squash is governed by twodifferent genes, with each gene existing in two alleles, propose amechanism to account for this 9:6:1 ratioarrow_forward
