Consider a cross between a true breeding purple flowered pea plant (genotype PP) and a true breeding white flowered pea plant (genotype pp) that produces all heterozygous F1 offspring. An F1 intercross is conducted between two of the F1 offspring, resulting in the F2 generation. What is the expected phenotype outcome of the F2 individuals resulting from the F1 intercross?

Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?
Hemophilia and color blindness are both recessive conditions caused by genes on the X chromosome. To calculate the recombination frequency between the two genes, you draw a large number of pedigrees that include grandfathers with both hemophilia and color blindness, their daughters (who presumably have one chromosome with two normal alleles and one chromosome with two mutant alleles), and the daughters sons. Analyzing all the pedigrees together shows that 25 grandsons have both color blindness and hemophilia, 24 have neither of the traits, 1 has color blindness only, and 1 has hemophilia only. How many centimorgans (map units) separate the hemophilia locus from the locus for color blindness?
You have a pure breeding plant with red flowers, yellow seeds and red-veined leaves. You cross this with another pure breeding plant that has white flowers, pink seeds and yellow leaf veins. All of the offspring (F1) have white flowers, yellow seeds and orange leaf veins. Assuming all three loci are independently assorting, use this information to answer the following question: If two F1 offspring are crossed with each other and 1000 F2 are obtained, approximately how many offspring should have orange leaf veins? a. 1000 b. 750 c. 500 d. 250 e. Cannot be determined with this information
A true-breeding pea plant with round and green seeds was crossedto a true-breeding plant with wrinkled and yellow seeds. Roundand yellow seeds are the dominant traits. The F1 plants wereallowed to self-fertilize. What are the following probabilities forthe F2 generation?A. An F2 plant with wrinkled, yellow seeds.B. Three out of three F2 plants with round, yellow seeds.C. Five F2 plants in the following order: two have round, yellowseeds; one has round, green seeds; and two have wrinkled,green seeds.D. An F2 plant will not have round, yellow seeds
Consider a dominant pure-breeding parent pea plant that had green peas, was tall, and had purple flowers, was crossed with a recessive pure-breeding parent that had yellow peas, was short, and had white flowers. In order to produce a gene map, Doja Cat selects a single F1 heterozygote offspring and test crosses it to produce 80 F2 offspring that collectively exhibit eight different phenotypes with 10 organisms of each phenotype. Can she automatically assume that the three genes in the pea plants were linked?
A pea plant that is dwarf with green, wrinkled seeds was crossedto a true-breeding plant that is tall with yellow, round seeds. TheF1 generation was allowed to self-fertilize. What types of gametes,and in what proportions, would the F1 generation make? Whatwould be the ratios of genotypes and phenotypes of the F2generation?
. Consider the imaginary trait, bristles with split-ends, a trait hypothesized to be X-linked dominant. In a cross, the P1 virgin females were homozygous wild type while the males had bristles with split-ends. The F1 84 males were all wild type while the 90 females all had split-ends. In addition, the data for the F2 generation revealed 26 wild type males, 35 wild type females, 29 split-end males and 40 split-end females. Is this what is to be expected? Use chi-square to prove your position.
In the tomato, yellow flowers (Y) is dominant to white flowers (y). A true-breeding yellow flowered strain is crossed with a true-breeding white flowered strain.A. If the F1 generation is self crossed, what will be the genotypes and phenotypes of the progeny and in what portions are they expected? B. If an F1 plant were crossed with a plant from true-breeding white flowered strain, what will be the genotypes and phenotypes of the progeny and in what portions are they expected?
Consider a two-factor cross between a pure breeding plants: one with purple flowers and yellow seed pods and another with white flowers and green seed pods. 100% of F1 offspring have purple flowers and green seed pods. If these F1 plants are self-fertilized, what proportion of F2 offspring are expected to have purple flowers and green seed pods? You may assume independent assortment of the flower color and seed pod color alleles. Please give your answer as a decimal rounded to two decimal places (e.g. 0.69).
You perform a cross between two true-breeding strains of zucchini, One has green fruit and the other has yellow fruit. The F1 plants are all green, but when these are crossed, the F2 plants consist of 9 green: 7 yellow. A. Assuming that wild-type zucchini are green, how would you describe the phenomenon that occurred in the F1 of part (e) of the parents and progeny?.
The garden flower Salpiglossis sinuata (paintedtongue) comes in many different colors. Severalcrosses are made between true-breeding parentalstrains to produce F1 plants, which are in turn selffertilized to produce F2 progeny.Parents F1 phenotypes F2 phenotypesred × blue all red 102 red, 33 bluelavender × blue all lavender 149 lavender, 51 bluelavender × red all bronze 84 bronze, 43 red, 41 lavenderred × yellow all red 133 red, 58 yellow, 43 blueyellow × blue all lavender 183 lavender, 81 yellow, 59 bluea. State a hypothesis explaining the inheritance offlower color in painted tongues.b. Assign genotypes to the parents, F1 progeny, andF2 progeny for all five crosses.c. In a cross between true-breeding yellow and truebreeding lavender plants, all of the F1 progeny arebronze. If you used these F1 plants to produce anF2 generation, what phenotypes in what ratioswould you expect? Are there any genotypes thatmight produce a phenotype that you cannot predictfrom earlier experiments, and if…
Two genes of a flower, one controlling blue (B) versus white(b) petals and the other controlling round (R) versus oval (r)stamens, are linked and are 10 map units apart. You cross ahomozygous blue oval plant with a homozygous white round plant. The resulting F1 progeny are crossed with homozygouswhite oval plants, and 1,000 offspring plants are obtained.How many plants of each of the four phenotypes do youexpect?
