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 the garden pea, orange pods (o) are recessive to green pods (+), and sensitivity to pea mosaic virus (v) is recessive to resistance to the virus (+). A plant with orange pods and sensitivity to the virus was crossed to a true-breeding plant with green pods and resistance to the virus. The F1 progeny were then test-crossed to plants with orange pods and sensitivity to the virus with the following results: 160 orange pods, virus sensitive 36 orange pods, virus resistant 165 green pods, virus resistant 39 green pods, virus sensitive A goodness of fit analysis for the operative genetic mechanism behind these obtained results will result to a X2 value of ____ which is (below, above) the alpha value, and interpreted as (significant, not significant). Hence the hypothesis that the data is due to (dihybrid self-cross, linkage, epistasis) is (accepted, not accepted). Express answer in decimal form. Significant # of decimal…
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?
(please explain clearly and provide correct answer)
1. Please consider the following pedigree. I 1 2 II 1 a) Assume that colour is controlled by a single sex-influenced gene where orange is expressed preferentially in females. Individuals I-1 and I-2 are homozygous for orange and blue respectively. Which individual/s in generation II will be blue? b) If colour is a controlled by cytoplasmic DNA, which individual/s in generation II will be orange?
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

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?
