Please provide details:
White fruit color in summer squash is governed by a dominant gene (W) and colored fruit by its recessive allele (w). Yellow fruit is governed by an independently assorting hypostatic gene (Y) and green by its recessive allele (y). When dihybrid plants are crossed, the offspring appear in the ratio of 12 white : 3 yellow : 1 green. What fruit color ratio is expected from the cross of WwYy to Wwyy?

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...

Name: ID: A In summer squash, there are two genes that determine fruit color. The two genes sort independently. Two white-fruited plants are crossed. Both parents are known to be heterozygous for both genes The cross produces the following offispring: 20 green-fruited plants, 58 yellow-fruited plants, and 218 white-fruited plants. 13. A.

1) Coat color in mice is determined by several independently assorting autosomal genes. Gene A is involved in the distribution of pigment along the hair. A dominant allele (A) produces a hair color called "agouti"--the hair has dark pigment at the base and tip of each hair shaft and yellow pigment in the central portion of the shaft. Homozygous recessive mice (aa) are missing the yellow stripe and thus have solid dark-colored hair. Gene B is involved in the color...

Questions 64-65 refer to the following. In a plant, axial flower (T) is dominant to terminal flower (t) and red fruit color (Y) is dominant to yellow (y). These effects are caused by two independently assorting autosomal genes. An individual terminal red plant was crossed with an individual axial, yellow plant to produce offspring which were 1/2 axial, red: 1/2 terminal, red. The genotype of the crossed terminal red plant was: ttyy ttYy ttYY TTyy Ttyy In the cross described...

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...
