A plant's flower colour is determined by the pathway shown below:

white¹ ----Gene A-----> white²----Gene B---->Blue

If you perform a dihybrid testcross (ie AaBb x aabb) what will the offspring look like?

	3/4 blue, 1/4 white
	9/16 white, 7/16 blue
	3/4 white, 1/4 blue
	1/2 white, 1/2 blue
	9/16 blue, 7/16 white

BR In harebells, wild type flower colour is blue. You have found three white petalled mutants which are homozygous pure breeding strains. When you cross each of these with a wild type pure breeding strain, all the offspring have blue flowers, and the F2 gives a 3:1 ratio of blue to white. When you cross two of the white mutants together, the Fl generation are all blue! When you self the FI, the F2 generation gives a ratio of 9...

In sweet peas, two genes (genes A and B) control flower color. The dominant alleles of both genes produce enzymes that function in the biochemical pathway shown to convert colorless precursors to a purple pigment. The recessive alleles do not produce enzyme. Therefore, at least one dominant allele of both gene A and gene B are required for purple flowers. Answer the questions about this biochemical pathway. ΑΑ, Αα BB, Bb Enzyme A Enzyme B Colorless precursor 1 Colorless precursor...

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...

Question 3 1 pts The color of chickens is determined by gene B, such that BB=black, Bb = gray, and bb = white. A second gene R controls comb shape, with dominant rose and recessive single comb. If a white single-combed chicken is mated with a gray chicken that is heterozygous for rose comb, what fraction of the offspring will be gray with rose comb? 1/4 9/16 1/8 O 3/8 1/16

15. The gene for petal color in a flower has incomplete dominance, so that individuals with two Al alleles (AIA) are red, individuals with two A2 alleles (A2A2) are white, and individuals with one of each allele (AIA2) are pink. In a cross between a red flower and a white flower, what is the probability of getting a pink offspring? (2 points) In a cross between a red flower and a pink flower, what is the probability of getting a...

Suppose that the "Green" phenotype is controlled by two genes, A and B, as shown in the diagram below. Allele A' produces enough enzyme 1 to convert "White" to "Red." Allele 'a' produces no enzyme 1. Allele 'B' produces enough enzyme 2 to convert "Red" to "Green." Allele 'b' produces no enzyme 2. The A and B genes are both autosomal and assort independently. White Enzyme 1 Red Enzyme 2 Green What will be the expected phenotypic ratio of the...
