A homozygous tomato plant with orange fruit and white flowers was crossed with a homozygous tomato plant with red fruit and red flowers. The F1 all had orange fruit and white flowers. The F1 were testcrossed by crossing them to homozygous recessive individuals and the following offspring were obtained: Orange fruit and white flowers- 64 Red fruit and red flowers- 69 Orange fruit and red flowers- 14

A parental cross between homozygous wild-type red eyed females (X+ X+) were crossed with white eyed males (XwY). The F1 generation consisted of phenotypic X+Xw females and X+Y males. The F2 generation was produced by crossing the F1 generation and consisted of a ratio of 2 red eyed females (X+ X+ and X+ Xw) : 1 red eyed male (X+Y) : 1 white eyed male (XwY). Attached is a picture of a chi square analysis based on the results from the F2 generation. Please discus what conclusions can be made based on the data/findings. What inheritance pattern is this?
A trait in garden peas involves the curling of leaves. A two-factorcross was made by crossing a plant with yellow pods and curlingleaves to a wild-type plant with green pods and normal leaves. AllF1 offspring had green pods and normal leaves. The F1 plants werethen crossed to plants with yellow pods and curling leaves. Thefollowing results were obtained: 117 green pods, normal leaves115 yellow pods, curling leaves78 green pods, curling leaves80 yellow pods, normal leavesA. Conduct a chi square analysis to determine if these two genesare linked.B. If they are linked, calculate the map distance between the twogenes. How accurate do you think this calculated distance is?
Imagine you are performing a cross involving gerden pea plants. What F1 offspring would you expect if you cross plants with green seedsand plants that are homozygous for the yellow seed colo allele? -yellow seed is dominant over green 100 percent yellow - green sedds 100 percent yellow seeds 50 percent yellow, 50 percent green seeds 25 percent green, 75 percent yellow seeds
Chickens, like all birds, have ZZ-ZW sex determination. The bar-feathered phenotype in chickens results from a Z-linked allele that is dominant over the allele for nonbar feathers. A barred female is crossed with a nonbarred male. The F1 from this cross are intercrossed to produce the F2. What will the phenotypes andtheir proportions be in the F1 and F2 progeny?
In the tomato, three genes are linked on the same chromosome. Tallis dominant to dwarf, skin that is smooth is dominant to skin that ispeachy, and fruit with a normal rounded tomato shape is dominantto oblate (flattened) shape. A plant that is true-breeding for thedominant traits was crossed to a dwarf plant with peachy skin andoblate fruit. The F1 plants were then testcrossed to dwarf plants withpeachy skin and oblate fruit. The following results were obtained: 151 tall, smooth, normal33 tall, smooth, oblate11 tall, peach, oblate2 tall, peach, normal155 dwarf, peach, oblate29 dwarf, peach, normal12 dwarf, smooth, normal0 dwarf, smooth, oblate Construct a genetic map that shows the order of these three genesand the distances between them?

In corn, a colored aleurone is due to the presence of an R allele; r/r is colorless. Another gene controls the color of the plant, with g/g being yellow and G_being green. A plant of unknown genotype is test-crossed, and the following progeny plants were obtained. Colored green 89 Colored yellow 13 Colorless green 9 Colorless yellow 92 What was the phenotype and genotype of the plant used for the test cross? A. Colorless green - rG/rg B. Colorless yellow - rg/rg C. Colored yellow - Rg/rg D. Colored green - RG/rg
Red eyes is the wild-type phenotype in Drosophila, and severaldifferent genes (with each gene existing in two or more alleles) affect eye color. One allele causes purple eyes, and a different allelecauses vermilion eyes. The purple and vermilion alleles are recessive to red eye color. Two types of crosses provided thefollowing data:Cross 1: Males with vermilion eyes × females with purple eyes354 offspring, all with red eyesCross 2: Males with purple eyes × females with vermilion eyes212 male offspring with vermilion eyes221 female offspring with red eyesExplain the pattern of inheritance based on these results. Whatadditional crosses might you make to confirm your hypothesis?
You have been given a virgin Drosophila female. You notice that the bristles on her thorax are much shorter than normal. You mate her with a normal male (with long bristles) and obtain the following F1 progeny1 3 short-bristled females, 1 3 long-bristled females, and 1 3 long-bristled males. A cross of the F1 long-bristled females with their brothers gives only long-bristled F2. A cross of short-bristled females with their brothers gives 1 3 short-bristled females, 1 3 long-bristled females, and 1 3 long-bristled males. Provide a genetic hypothesis to account for all these results, showing genotypes in every cross.
In corn plants, a dominant allele (K) allows kernel colour and a recessive allele (k) inhibits kernel colour when homozygous. On a different chromosome, the dominant gene P causes purple kernel colour and the homozygous recessive genotype causes red kernel colour.A true breeding white corn plant was crossed with a purple corn plant, yielding 50% red corn plants and 50% purple corn plants.What are the genotypes of the parental corn plants? Select one: a. KKPp kkpp b. KkPP kkPP c. kkPp KkPp d. KKPP kkPp
A particular breed of dog can have long hair or short hair. Whentrue-breeding long-haired animals were crossed to true-breedingshort-haired animals, the offspring all had long hair. The F2 generation showed a 3:1 ratio of long- to short-haired offspring. Asecond gene affects the texture of the hair. The two variants arewiry hair and straight hair. F1 offspring from a cross of these twovarieties all had wiry hair, and F2 offspring showed a 3:1 ratio ofwiry-haired to straight-haired puppies. Recently, a breeder of theshort- and wiry-haired dogs found a female puppy that was albino.Similarly, another breeder of the long- and straight-haired dogsfound a male puppy that was albino. Because the albino trait is always due to a recessive allele, the two breeders got together andmated the two dogs. Surprisingly, all of the puppies in the litterhad black hair. How can you explain this result?
