Assume that white is the dominant color over yellow in squash. If pollen from the anthers of a heterozygous white-fruited plant is placed on the pistil of a yellow-fruited plant, show, using ratios, the genotypes and phenotypes you would expect the seeds from the cross to produce.

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...

Clownfish exhibit three phenotypeni red, yellow, and orange. If a red clownfish is mated with a yellow clownfish, the resulting progeny are all orange. a. What type of inheritance pattern do you suspect? incomplete dominance b. Construct a Punnett square to illustrate a cross between two RRRR orange clownfish. (make up letters to represent the alleles) 15. RRR Genotypic ratio: la: Phenotypic ratio: 1: 2!! There are 4 alleles (C.ch, ch, and e) of the gene for coat...

5. Mendel first made sure that he had purebred dominant green pod plants and then he crossed them with yellow pod plants. What is the probability that the offspring are green? 6. Second, Mendel used the offspring from the first cross and allowed them to self pollinate. What is the probability that the resulting offspring are yellow? 7. Fur...

6. In guinea pigs, coat color can be white, cream or yellow. Of these three phenotypes, only the cream-colored guinea pigs never breed true. When two cream-colored guinea pigs are crossed, We are yellow, Y are cream and are white. A cream-colored guinea pig by white guinea cross yields / cream and white offspring. a. How many genes control coat color in the guinea pig? b. Give the mode of inheritance of coat color in the guinea pig. c. Why...

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...

can i get help with these 2 problems?
In the yawncat (a rare hypothetical animal), the black coat color allele B is dominant to the brown allele b, but the B locus can only be expressed if the animal has an mm genotype at a second gene locus. Animals that are M_are yellow regardless of which allele from the B locus is present. a. A mating between a yellow-tailed male yawncat and a brown-tailed female yawncat produces 16 offspring with...
