You've discovered a new plant species in which green fruit color (y) is recessive to yellow fruit color (Y), and long fruit shape (r) is recessive to round fruit shape (R).
The genes for fruit color and shape are located on the same chromosome and are 16 m.u. apart.
Question: Determine the proportions of progeny of each phenotype produced for this cross. Yr/yR x yr/yr
This is part 2 of 2 (involving green fruits).

Example Problem 2 A plant has fruits where green is dominant to blue, and hairy is dominant to waxy. The genes for color and texture are on the same chromosome, and have a recombination frequency of 14%. True breeding green, waxy plants are crossed with true breeding blue, hairy plants. The F1 is test-crossed with a blue and waxy plant. What are the expected genotypes, phenotypes, and phenotype proportions of the test-cross progeny?

In a certain plant, a dominant allele for one gene, R, produces round fruit and the recessive allele, r, produces oblong fruit. A dominant allele of a second gene, Y, produces yellow flowers and the recessive allele, y, produces white flowers. The two genes are linked on chromosome IV. A plant ( ry / ry ) with normal chromosomes is crossed to a plant (R Y/R Y) homozygous for a reciprocal translocation between chromosomes IV and VIII. The presence of...

2. Yellow body (y), vermillion eye color (v) and miniature body (m) are recessive X-linked traits in Drosophila. The order of the genes on the chromosome is y-v-m. The following cross is performed: y v m /y+ v+ m+ (female) X y v m/Y (male) The map distances shown below were generated using 1000 male progeny. y-v - 32.0 cM; y-m - 34.3 cM; v-m - 4.0 cM Which of the following statements is FALSE? The correct answer is B...

Two independently assorting genes help determine fruit color in squash. At the first locus, the W allele codes for a dominant white phenotype, whereas the w allele allows colored squash. At the second locus, the allele Y codes for a dominant yellow phenotype, and the allele y codes for a recessive green phenotype. The interaction between these two genes is an example of dominant epistasis, with the W locus acting as the epistatic locus and the Y locus acting as...

A cross in Drosophila involved the recessive, X-linked genes yellow (y), white (w), and cut (ch. A yellow-bodied, white-eyed female with normal wings was crossed to a male whose eyes and body were normal but whose wings were cut . The F, females were wild type for all three traits. • The F, males expressed the yellow-body and white-eye traits. The cross was carried to an F2 progeny, and only male offspring were tallied. On the basis of the data...

A new gene is being investigated in fruit flies. The recessive allele of this gene (b) causes the wings to develop a blue color, while the dominant allele (b) permits wild-type colorless wings to develop. Preliminary studies indicate that this new gene is located on the X-chromosome. You decided to perform a two-point testcross to determine its position relative to the well-established garnet eyes gene (g). You cross a female heterozygous for both genes with a testcross male fly, and...
