4). In papayas, sour fruit (S) is dominant over sweet fruit(s), and green skin (G) is dominant over yellow skin (g).The genes for these characteristics independently assort.A homozygous plant with sour fruit and green skin iscrossed with a homozygous plant with sweet fruit andyellow skin. Two individuals from the F1 generation arethen crossed to produce an F2 generation.

1. The height of a wheat plant is determined by several genes. In a variety the minimum size is 12 inches and the maximum is 24 inches. 12-inch plants were crossed with 18-inch plants, and produced an 18-inch F1. The F1 was allowed to cross each other, and an F2 was obtained in which the 12 and 24 inch plants were obtained with a frequency of 2/8195. How many genes are involved in determining plant size in this variety of wheat? Select one: a. 5b. 6c. 4d. 3
You have two true-breeding strains of coneflower. One strain has purple flowers and purple stems. The other strain has white flowers and green stems. When you cross these strains the F1 generation has purple flowers and purple stems. From this information you know that purple flowers is dominant to white flowers and that purple stems is dominant to green stems. In terms of genetic mechanisms, there could be two explanations: (1) flower color and stem color are each controlled by separate, independently segregating genes, and (2) there is one gene controlling both flower color and stem color. A. If explanation #1 is correct what would you see if the F1 generation were self-crossed to produce an F2 generation. Make up appropriate genetic symbols for this model and work out the cross to the F2 generation. B. If explanation #2 is correct what would you see if the F1 generation were self-crossed to produce an F2 generation. Make up appropriate genetic symbols for this model and work out the…
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? (show Punnett square) A woman homozygous dominant for albinism marries a man who is homozygous recessive for albinism. What are the possible genotypes and phenotypes percentages for their offspring? A man that can roll his tongue is heterozygous for the trait marries a woman that cannot roll her tongue. They have a child. The rolling tongue is dominant to not rolling tongue. What is the man’s genotype for tongue rolling? The women? Show the Punnett square for the child’s genotype Give the probability (percent chance) that the child can or cannot roll their tongue. Oh no! The F1 and F2 generation seed packet labels were mixed around. How would we know which seeds we planted by observing the color of the leaves? (Hint: What are the genotypes of the two generations? What color leaves do they produce in what ratios?)
In corn plants, a dominant allele (I) inhibits kernel colour, but the recessive allele (i) permits colour when homozygous. At a different locus, the dominant gene P causes purple kernel colour, and the homozygous recessive genotype pp causes red kernels. If plants that are heterozygous at both loci are crossed, what will be the phenotypic ratio of the F1 generation?
9. A true-breeding blue-flower, wrinkled-seed, short-stem, yellow-leaf plant was crossed with a true-breeding red-flower, round- seed, long-stem, green-leaf plant and all of the progeny had the following phenotype: purple-flower, round seed, short-stem, approximately half of the leaves on the plants were yellow and the other half green. Assuming a single gene controls each trait, describe the inheritance pattern for each gene. Inheritance Pattern a. Gene Flower color Seed shape Stem length Leaf color

5. If flower color shows codominance, and R = red and r = white, what will the %3D %3D offspring of a cross between RR x rr look like? * 100% red 75% red, 25% white 100% red and white 100% pink 25% red, 50% red and white, 25% white
A type of tomato (Solanum lycopersicum) produces fruit in three possible colors: red, green, and orange. You cross a true-breeding orange-fruited plant with a true-breeding green-fruited plant, and all the F1 offspring are red. You intercross the red F1s, and the resulting F2 generation consists of 108 red-, 40 orange-, and 44 green-fruited plants. 1) What type of epistasis is acting (dominant, recessive, duplicate dominant, or duplicate recessive)? 2) Assign the phenotypes to a modified 9:3:3:1 ratio. (Do not just calculate the actual ratio of the phenotypes.) Red : _____Orange : _____Green: _____
2. A trait in garden peas involves the curling of leaves. A dihybrid cross was made involving a plant with yellow pods and curling leaves to a wild-type plant with green pods and normal leaves. All F1 offspring had green pods and normal leaves. The F1 plants were then crossed to plants with yellow pods and curling leaves. The following results were obtained: 117 green pods, normal leaves 115 yellow pods, curling leaves 78 green pods, curling leaves 80 yellow pods, normal leaves A. Conduct a chi square analysis to determine if these two genes are linked. B. If they are linked, calculate the map distance between the two genes. How accurate do you think this distance is?
1. You are given a female F1 of unknown genotype. You cross the female fly to a homozygous male that has forked bristles and malformed eyes. The offspring of the cross is shown below: (Define symbols for your traits) Phenotype Forked bristles, normal eyes 752 Number Genotype Forked bristles, malformed 56 eyes Malformed eyes, normal bristles Normal eyes, normal bristles 820 64 a. What are the genotypes of the offspring? b. Based on the progeny, what were the genotypes of the F1 parents? What is the distance between for and mal?
In venetian violets, three phenotypes occur with respect to flower color: a deep violet (almost back), a white, and a pale lavender. Two pale lavender flowered plants have been crossed. The F1 from this cross has individuals with deep violet flowers, with pale lavender flowers, and individuals with white flowers. A. what are the parent genotypes? B. what would the expected phenotypic ratio be in these F1 plants?
16. In Jimpson weed, the alleles encoding purple and white flower color display incomplete dominance. Heterozygous plants have mauve-colored flowers. If two mauve-flowered plants are crossed, what is the expected phenotypic ratio of the F₁ generation?
