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 the hypostatic locus. Double heterozygotes (WwYy) are mated with each other to produce a total of 480 offspring. What are the squash colors produced from this cross and how many of each color would be expected? Show your work and circle your final answers.

    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? 1/2 white, 1/4 yellow, 1/4...

    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...

    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.

    In rats, at least 2 different genes interact to determine hair color. The allele A causes a yellow-colored coat and the allele R produces a black coat. If both dominant alleles are present (genotype A-R) the rats are gray, and if none are present (aarr) the rats are cream-colored. a. If two heterozygous gray rats are mated and have 16 babies, show the expected number of babies of each color. b. If a heterozygous gray rat is mated with cream-colored...

Allele B encodes a functional Enzyme 2, which converts " smashing " to " fabulous ". The recessive allele B encodes a functional and B genes are both autosoaml and assort independently. A...

    In rats, several independently assorting autosomal genes affect coat color. Gene A controls the distribution of yellow pigment in hair, and gene B causes black pigmentation. The two genes interact as follows: A–B– (gray), A–bb (yellow), aaB– (black), and aabb (cream). These genotypes are only expressed in the presence of the dominant allele of a third gene, C; rats with genotype cc are albino. a.    Deduce the genotype of each albino mice, to the extent that is possible, in the...

    please answer two question below thankyou e) 9; 9 3. In another plant species, the presence and type of hairs on the plant are controlled by epistatic interaction between two independently assorting genes. Gene C determines whether the plant has hairs (dominant) or not (recessive); Rene D determines whether the hairs are straight (dominant) or curly (recessive). In a cross between a straight-haired plant and a curly- haired plant, 1/4 of the offspring have no hairs. 3/8 have straight hairs,...
