Based in my hypothesis I need to construct a punnett diagrams can you please help me. Than you ObservationWhat major change did you observe in the F1 generation compared to the parent generation?The genotype is the most significant alteration in the f1 generation. The adrosophilas in the p generation were allhomozygotes, but in the F1 generation, they are all heterozygotes. Also, the males' eyes were red on the parents,but they are white on the males of the F1 generation, and white eyed females from the Pngave bird to red eyedfemales in the F1 generation.HypothesisWhat is your hypothesis to explain the phenotypes (white/red eye trait) observed ingeneration? (Punnett square may be used to explain).your F1Allele (R) causes red eyes.Allele (r) for white eye color -> in this example, sex/linked includes the gene for the red white eye feature, whichis X/linked. Alled (R), which is red in color, is dominant over allele (r), which is white in color. The punnet squareillustrates how F1 generation is formed from parent generation.Prediction10tv23&34578WERYSDFGH.KCVM F, Results After 14 Days.

Neep help ASAP. A red flowered plant was crossed with a blue flowered plant and produced all purple flowered plants. When the purple flowered plants were crossed with each other they produced 5 red plants, 5 blue plants, 20 deep purple plants, 20 light lilac plants, and 30 purple plants How many genes are involved in the color production? Assume that red color is caused by an A allele and blue color by a B allele and determine the likely genotype of the plants in the F2 generation.
This problem leads you through the derivation of acorrected equation for RF in yeast tetrad analysis thattakes into account double crossover (DCO) meioses. A yeast strain that cannot grow in the absence ofthe amino acid histidine (his−) is mated with a yeaststrain that cannot grow in the absence of the aminoacid lysine (lys−). Among the 400 unordered tetrads resulting from this mating, 233 were PD, 11 wereNPD, and 156 were T.a. What types of spores are in the PD, NPD, andT tetrads?b. Are the his and lys genes linked? How do you know? c. Using the simple equation RF = 100 × [NPD +(1/2)T]/total tetrads, calculate the distance in mapunits between the his and lys genes.d. If you think about all the kinds of meiotic eventsthat could occur (refer to Fig. 5.24), you can seethat the calculation you did in part (c) may substantially underestimate RF. What kinds of meioses(NCO, SCO, or DCO) generated each of the tetradtypes in this cross? e. What incorrect assumptions does the simple RFequation…

EXAMPLE PROBLEM A plant with orange, spotted flowers was grown in the greenhouse from a seed collected in the wild. The plant was self-pollinated and gave rise to the following progeny: 88 orange with spots, 34 yellow with spots, 32 orange with no spots, and 8 yellow with no spots. What can you conclude about the dominance relationships of the alleles responsible for the spotted and unspotted phenotypes? What can you conclude about the genotype of the original plant that had orange, spotted flowers?
F1 hybrids between two species of cotton, Gossypium barbadenseand Gossypium hirsutum, are very vigorous plants. However, F1crosses produce many seeds that do not germinate and a high percentageof very weak F2 offspring. Suggest two reasons for theseobservations.
3. The inheritance of petal color in some plant species is alleged to be codominant. A group of pure (homozygous) white carnations were deliberately pollinated with pollen from pure red carnations. Fertilized seeds were collected, and after germination and growth of this F1 generation, they were allowed to freely pollinate one another. The color of the flower on each plant in the F2 generation was tallied. 239 red, 307 white, and 615 pink plants were recorded. Apply a ?2 analysis to determine the statistical validity of the assumed inheritance pattern. Show every step in your thought process along with all relevant calculations and written support. HINT: For this problem, you should DEFINITELY construct the two Punnett squares to reveal the phenotypes of the F1 and F2 generations. Please answer very soon will give rating surely
