In the common bluebell, two linked, autosomal genes control flower color and plant height. With the given information, find the expected F1 generation phenotypes and the frequencies of the F1 generation.

B (blue flowers) is dominant to b (white flowers)

T (tall plants) is dominant to t (dwarf plants)

If the crossover frequency between the two loci is 26%, what will the expected F1 phenotypes and their frequencies from the following cross:

a) BT//bt x bt//bt

b) Bt//bT x bt//bt

c) Bt//bT x Bt//bT

8. You are interested in two plant genes: one for plant height and one for flower color. You cross a tall white plant to a short red plant. All of the progeny are tall pink plants What is the genotype of the tall white parental plant? What is the genotype of the short red parental plant? What is the genotype of the F1 tall pink plant? What six phenotypic classes of plant would result from a cross between two of...

You are studying three linked genes in snapdragons. The flower color locus is in the center. There are 11.3 cM between the flower color locus and the plant height locus. There are 10.7 cM between the flower color locus and the leaf type locus. The coefficient of coincidence is 0.8. Pure-breeding tall, red-flowered plants with fuzzy leaves were crossed to pure-breeding dwarf, blue-flowered plants with smooth leaves. The F1 were testcrossed. Calculate the proportion of the testcross progeny that are...

in garden peas, genes controlling height, flower color, and seed size are on the third autosome gene map: height-----10 mu------- color-------------20mu------ seed size a purebred tall, red flowered, large-seeded plant is crossed with a purebred short, white flower, small seeded plant. All of the offspring are medium height, pink, and small seeded. A. What proportions of the pollen produced by the F1 will carry the tall, red flowered and large seed alleles? B. if the F1 is allowed to produce...

You are studying recessive mutations of three autosomal, linked genes in guinea pigs: fur color (y, yellow); fur texture (wv, wavy); ear size (l, large). The data in columns A and B was obtained from crosses of heterozygous F1 females with homozygous testcross males (recessive for all three traits). Column: A B C D E F2 Phenotype # Observed Corresponding Genotype P or SCO or DCO Genotype Written in Correct Order on Homologs yellow 310 ywv+l+ P...

Flower color in Orcish Thimbleweed (Anemone sarumani) is controlled by two genes. At the G locus, red flowers (G) is dominant to slate gray (g). At the W locus, colored flowers (W) is dominant to colorless (w). Plants with the genotype G-W- are red, ggW- are slate gray, and --ww are white. A true-breeding plant with red flowers is crossed with a true-breeding plant with white flowers, producing F1 offspring with slate gray flowers. What is the expected phenotypic ratio...

Assume that flower color in petunia is controlled by two genes. After making a dihybrid cross, the following progeny were observed: 9 purple-flowered petunia : 7 white-flowerd petunias a) What form of epistasis is working to control this trait? b) One of the heterozygous individuals used in the above dihybrid cross was test-crossed. What phenotypic classes do you expect in the progeny and at what frequencies? Show your work/thought process.

In Mendel's pea plants, the genes that code for flower color, seed color and seed shape are on 3 different chromosomes. For flower color, purple is dominant over white, yellow seeds are dominant over green and round seeds are dominant over wrinkled seeds. If you crossed two parents who were heterozygous for all 3 genes, how many purple flowered, round and yellow seeded plants would you expect in the offspring generation? correct answer is 27/64 please show work thank you

Two autosomal genes control horn color in dragons. Pure-breeding gold-horned dragons were mated to pure-breeding silver-horned dragons. All of the F1 were gold. The F1 were intermated and the F2 generation consisted of 147 gold, 16 silver and 93 bronze. Conduct a chi-square test to test the appropriate type of epistasis. In the chi-square test, what is the expected number of gold-horned dragons? Round to two decimal places. Conduct a chi-square test to test the appropriate type of epistasis. In...

Drosophila has three linked autosomal genes that determine different traits. These genes are black (b), vestigial (vg), and singed(sn). Each of the three genes has two alleles: a dominant wild type allele, indicated by a "+" (plus) and a recessive mutant allele indicated by a "-" (minus). (These mutant alleles cause dark black spots, short "vestigial" wings, and bent "singed" hairs, respectively, when homozygous). A testcross is conducted between females that all have the same genotype and are triple heterozygotes...

In peas the flower color and pollen length genes are very close together on the same chromosome. Purple flowers (P are dominant to white (p), and long pollen (L) is dominant to short pollen (l). A true breeding variety of peas with purple flowers and short pollen is crossed to a true breeding variety with white flowers and long pollen. The F1 plants are then self-crossed to produce an F2 generation. a. What is the genotype and phenotype of the...
