- 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.A pea plant heterozygous for both green pod(G,g)and tall plants(T,t)is allowed to self-fertilize. Of the 320 plants in the offspring, how many would you expect to be short plants with green pods?Two plants in a cross were each heterozygous for two gene pairs (AB /ab) whose loci are linked and 30 map units (mu) apart. (Recall that 1 mu is equal to 1% recombination between two genes.) Assuming that crossing over occurs during the formation of both male and female gametes and that the A and B alleles are dominant, determine the phenotypic ratio of their offspring. Part E: What proportion of the offspring of two plants (both (AB/ab ) will be A - B- if the genes are 30 mu apart? Part F: What proportion of the offspring of two plants (both (AB/ab)) will be A - bb if the genes are 30 mu apart? Part G: What proportion of the offspring of two plants (both (AB/ab)) will be aaB- If the genes are 30 mu apart? Part H: What proportion of the offspring of two plants (both (AB/ab)) will be aabb if the genes are 30 mu apart?
- 2. A tall, purple-flowered pea plant (AaBb) is allowed to self-pollinate. Determine the genotypic and phenotypic ratio using the dihybrid punnet square.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…Seedless watermelons that you find in the supermarketare triploids, where x = 11.a. At what frequency are balanced gametes generatedby triploid watermelons?
- A snapdragon with pink petals, black anthers, and longstems was allowed to self-fertilize. From the resultingseeds, 650 adult plants were obtained. The phenotypesof these offspring are listed here.78 red long tan26 red short tan44 red long black15 red short black39 pink long tan13 pink short tan204 pink long black68 pink short black5 white long tan2 white short tan117 white long black39 white short blacka. Using P for one allele and p for the other, indicatehow flower color is inherited.b. What numbers of red : pink : white would havebeen expected among these 650 plants?c. How are anther color and stem length inherited?d. What was the genotype of the original plant?e. Do any of the three genes show independentassortment?f. For any genes that are linked, indicate the arrangements of the alleles on the homologous chromosomes in the original snapdragon, and estimate thedistance between the genes1)A researcher crossed a homozygous yellow seed plant (YY) and a heterozygous yellowseed plant (Yy). Draw a Punnett Square and determine the genotype and phenotyperatios of the offspring. please explain it simple and no copypastes thanksLarge ear of corn has a total of 433 grains, including 26 Yellow & Shrunken, 73 Purple & Shrunken, 63 Yellow & Smooth, and 271 Purple & Smooth. Determine whether the ratio of corn kernels support the hypothesis that the plant is heterozygous.
- Seedless watermelons that you find in the supermarketare triploids, where x = 11.a. At what frequency are balanced gametes generatedby triploid watermelons?b. What is the probability that a particular seed in atriploid watermelon will be viable? (Recall that aviable seed is a euploid zygote.)c. What is the ploidy of the viable seed in part (b)?More than one answer may apply3. 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# of Green Leaves _________111______________ # of White Leaves ___________35______________ If a heterozygous F1 Tobacco plant was crossed to an albino plant, what is the expected number of green and white plants in the next generation?
