A pure breeding strain of squash that produced disk-shaped fruits was crossed with a pure- breeding strain having long fruits. The first filial generation had disk fruits, but the second filial generation showed a new phenotype, sphere, and was composed of the following proportions: disk 270, sphere 178, long 32. Propose an explanation for these results, and show the genotypes of P, First filial generation and second filial generation.

A pure-breeding strain of squash that produced disk-shaped fruits was crossed with a pure-breeding strain having long fruits. The F1 had disk fruits, but the F2 showed a new phenotype, sphere, and was composed of the following proportions: disk 270, sphere 178, long 32. Propose an explanation for these results, and show the genotypes of P, F1 and F2 generations.
A pure - breeding strain of squash that produced disk-shaped fruits was crossed with a pure-breeding strain having long fruits. The F1 had disk fruits, but the F2 showed a new phenotype, sphere and was composed of the following proportions: disk 270, sphere 178, long 32. Propose an explanation for these results, and show the genotypes of P, F1 and F2 generations.
A variety of opium poppy (Papaver somniferum L.) with lacerate leaves was crossed with a variety that has normal leaves. All the F1 had lacerate leaves. Two F1 plants were interbred to produce the F2. Of the F2, 249 had lacerate leaves and 16 had normal leaves. Give genotypes for all the plants in the P, F1, and F2 generations. Explain how lacerate leaves are determined in the opium poppy.
Purebred wrinkled, green-seeded pea plants were crossed with purebred round, yellow-seeded plants. The F1, all of which had round and yellow seeds, were then self-crossed resulting in the following F2: 172 plants with round and yellow seeds, 55 plants with round and green seeds, 58 plants with wrinkled and yellow seeds, and 15 plants with wrinkled and green seeds. Calculate the chi-square value and determine the p-value range. Which of the following are the correct chi-square values, p-value range, and whether you would accept or reject the hypothesis that these results are consistent with Mendelian predictions?
Assume that, in a series of experiments, plants with round seeds were crossed with plants with wrinkled seeds and the following offspring were obtained: 215 round and 185 wrinkled. How do you explain these observations and what would be the expected number of offspring with round seed and with wrinkled seed? The plants with round seeds are heterozygous for the round seed phenotype and F1 offspring is expected to show 200 round and 200 wrinkled seed. The plants with round seeds are homozygous for the round seed phenotype and F1 offspring is expected to show 300 round and 100 wrinkled seed. The plants with round seeds are heterozygous for the round seed phenotype and F1 offspring is expected to show 100 round and 300 wrinkled seed. The plants with round seeds are homozygous for the round seed phenotype and F1 offspring is expected to show 200 round and 200 wrinkled seed. The plants with round seeds are heterozygous for the round seed phenotype and F1 offspring is…
A snapdragon plant that bred true for white petals was crossed to a plant that bred true for purple petals and all the F1 have white petals. The F1 was selfed. Among the F2 three phenotypes were observed in the following numbers: White--> 240 Solid Purple --> 61 Spotted Purple --> 19 a) Propose the correct genetic explanation for this phenomenon. Define your genetic symbols and show the genotypes of the Parentals, F1, and F2 individuals above. You may use underscores ( _ ) where appropriate. Please clearly label your answer. b) Complete a chi square to defend your answer. Be sure to include chi, Ho and Ha. Do not forget to interpret your test.
A variety of opium poppy with lacerate leaves was crossed with a variety that has normal leaves. All the F1 plants had lacerate leaves. Two F1 plants were then interbred to produce the F2. Of the F2 plants, 249 had lacerate leaves and 16 had normal leaves. What are the genotypes of the plants in the P (parental), F1, and F2 generations? How are lacerate leaves determined in the opium poppy? Note: You can use the symbols A and B to represent the two genes involved. (How do we know there are two?)
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
In an intra-species cross performed in mustard plants of two different species (Brassica juncea and Brassica oleracea), a tall plant (TT) was crossed with a dwarf (tt) variety in each of the two species. The members of the F1 generation were crossed to produce the F2 generation. Of the F2 plants, Brassica juncea had 60 tall and 20 dwarf plants, while Brassica oleracea had 100 tall and 20 dwarf plants. Use chi-square analysis to analyze these results.
Suppose that the wild type phenotype for tomatoes is red, round fruit with three-parted leaves and that a strain of mutant tomatoes has yellow, pear-shaped fruit with entire leaves. A and a represent the alleles for fruit color, B and b represent the alleles for fruit shape, and C and c the leaf shape. Two tomatoes with the genotypes Aa Bb cc and Aa Bb CC are crossed. The resulting Punnett square is shown. One cell has been completed with the correct tomato phenotype. Fill in the rest of the Punnett square by placing a fruit and leaf phenotype in each cell.

A homozygous strain of corn that produces yellow kernels is crossed with another homozygous strain that produces purple kernels. When the F1 are interbred, 197 of the F2 are yellow and 153 are prurple. Give the genotypes of the yellow and purple F2 and propose a genetic model that explains the inheritance of these kernel colors in corn.
A purple flowering, smooth seed dihybrid plant (genotype PpSs) is test crossed with a white flowering, wrinkled seed plant (genotype ppss). These produce progeny in the following numbers of four phenotypes: 24:76:74:26 (purple flower + smooth seed coat: purple flower + wrinkled seed coat: white flower + smooth seed coat: white flower + wrinkled seed coat). a) What is the genotype of the original dihybrid plant? Specify which alleles are on each chromosome of the purple flowering, smooth seed plant (i.e. AB/ab or Ab/aB). b) How many map units separate the colour and seed coat genes? Show your calculations.
