Two genes in tomatoes are 61 mu apart; normal fruit (F) isdominant to fasciated fruit (f ), and normal number of leaves(Lf ) is dominant to leafy (lf ). A true-breeding plant with anormal number of leaves and fruit was crossed to a leafy plantwith fasciated fruit. The F1 offspring were then crossed to leafyplants with fasciated fruit. If this cross produced 600 offspring,what are the expected numbers of plants in each of the fourpossible categories: normal leaf number, normal fruit; normalleaf number, fasciated fruit; leafy, normal fruit; and leafy,fasciated fruit?

Individuals of genotype AaBb were mated to individuals of genotype aabb. One thousand offspring were counted, with the following results: 474 Aabb, 480 aaBb, 20 AaBb, and 26 aabb. What type of cross is it? Are these loci linked? What are the two parental classes and the two recombinant classes of offspring? What is the percentage of recombination between these two loci? How many map units apart are they?
Two genes in tomatoes are 61 mu apart; normal fruit (F) is dominantto fasciated (flattened) fruit ( f ), and normal number of leaves(Lf ) is dominant to leafy (lf ). A true-breeding plant with normalleaves and fruit was crossed to a leafy plant with fasciated fruit.The F1 offspring were then crossed to leafy plants with fasciatedfruit. If this cross produced 600 offspring, what are the expectednumbers of plants in each of the four possible categories: normalleaves, normal fruit; normal leaves, fasciated fruit; leafy, normalfruit; and leafy, fasciated fruit?
In a variety of tomato plant ,the leaves maybe pure green,pure white,or variegated (mixture). a)when 2 variegated plants were crossed,87 offspring were produced,of these 20 were green,46 were variegated and 21 remain died soon after germination.Draw a genetic diagram to explain these results,why did 21 of them died
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?
In cucumbers, speckled fruit color (u') is dominant to uniform fruit color (u), and large spines (ss") are dominant to small spines (ss). These two genes are linked at a map distance of 20.4 m.u. A true-breeding cucumber plant with speckled fruit and large spines is crossed with a true-breeding plant with uniform fruit color and small spines. One of the F1 plants is crossed with a plant with uniform fruit color and small spines. What percentage of the offspring of this cross are expected to have uniform fruit color and small spines? 39.8% 10.2% 79.6% 20.4%
In the garden pea, orange pods (o) are recessive to green pods (+), and sensitivityto pea mosaic virus (v) is recessive to resistance to the virus (+). A plant withorange pods and sensitivity to the virus was crossed to a true-breeding plant withgreen pods and resistance to the virus. The F1 progeny were then test-crossed toplants with orange pods and sensitivity to the virus with the following results:160 orange pods, virus sensitive 36 orange pods, virus resistant165 green pods, virus resistant 39 green pods, virus sensitive 1. What are the gamete frequencies of the recombinants and non-recombinants? 2. What are the expected frequencies of the recombinant and non-recombinantgenotypes?
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: _____
In tomatoes, regular leaves (L) are multilobed and serrated and potato leaves (l) are broad, smooth, and single (Image 1). Red fruit (F) is dominant to yellow fruit (f). A cross is carried out between two pure lines of tomato plants, one having regular leaves and red fruit and the other having potato leaves and yellow fruit. The F1 generation all have regular leaves and red fruit. The F1individuals are then crossed with one another. The information below represents two sets of data collected from the above cross.

Complete a Punnett square to determine the expected F2 progeny on the basis of Mendel’s Law of Independent Assortment, which states that the alleles for one gene segregate independently of the alleles for other genes during gamete formation. Record the phenotypes and the phenotype ratio of the F2 generation in lowest terms.
