A cross was made between a plant that has blue flowers and purpleseeds and a plant with white flowers and green seeds. The F1 generationwas then allowed to self-fertilize. The following data were obtained:F1 generation: All offspring have blue flowers with purple seeds.F2 generation: 208 blue flowers, purple seeds; 13 blue flowers,green seeds; 19 white flowers, purple seeds; and 60 white flowers,green seeds. Total = 300 offspring.Start with the hypothesis that blue flowers and purple seeds aredominant traits and that the two genes assort independently.Calculate a chi square value. What does this value mean withregard to your hypothesis? If you decide to reject your hypothesis,which aspect of the hypothesis do you think is incorrect (i.e., blueflowers and purple seeds are dominant traits, or the idea that thetwo genes assort independently)?

A cross was made between a plant that has blue flowers and purple seeds and a plant with white flowers and green seeds. The F1 generation was then allowed to self-fertilize. The following data were obtained. F1 Generation: All offspring have blue flowers with purple seeds. F2 Generation: 208 blue flowers, purple seeds 13 blue flowers, green seeds 19 White flowers, purple seeds 60 white flowers, green seeds Total: 300 The scientist needs to test if the two genes segregate independently and has formulated the null-hypothesis that there is no significant difference between the observed and expected data. What are the degrees of freedom for this experiment?
Given the following information, determine the inheritance of flower color in this plant and determine the genotypes of the parental individuals, which are from pure- breeding lines. CROSS 1 CROSS 2 purple X colorless all purple 9/16 purple colorless X red all purple as in Cross 1 F1 F1 F2 F2 3/16 red 4/16 colorless
A heterozygous pea plant that is tall with yellow seeds, TtGg, is allowed to self-fertilize. What is the probability that an offspring will be either tall with yellow seeds, tall with green seeds or dwarf with yellow seeds? Use the Sum Rule to calculate the probability asked in the problem.
In sweet pea plants, the trait for purple flowers (P) is dominant to the trait for red flowers (p).Similarly, the trait for long pollen (L) is dominant to the trait for round pollen (l).Two heterozygotes are crossed, yielding the following frequencies for the F1 generation:293 purple long plants;19 purple, round plants ;28 red, long plants ;87 red, round plantsUse the chi-square test to determine if these results are due to independent assortment. detailed explanation ?
If a plant is tall, has round seeds and purple flowers, with the genotype of TTRREE is crossed with a plant that is short and has wrinkle seeds and white flowers with the genotype ttrree. What would be the offspring of their F1 generation and F2 generation like? Form a Punnett square and write the phenotypic ratio?
One strain of periwinkleplants has green leaves and another strain has white leaves. Bothstrains are true-breeding. You do not know if the phenotypicdifference is due to alleles of a nuclear gene or an organellar gene.The two strains were analyzed using reciprocal crosses, and thefollowing results were obtained:A plant with green leaves is pollinated by a plant with whiteleaves: all offspring have green leaves.A plant with white leaves is pollinated by a plant with greenleaves: all offspring have white leaves. Is this pattern of inheritance consistent with simple Mendelianinheritance, where green is dominant to white, and/or is it consistentwith maternal inheritance?
A dihybrid cross is one in which two traits with two pairs of genes are studied at once. For example, we cross tall plants with round seeds (TTRR) with dwarf plants and wrinkled seeds. What is the expected phenotypic ratio of the F2 generation? O 3:1 9:3:3:1 O1:1 12 :1
In Primula vulgaris (primrose), purple flowers are dominant to white flowers, and short plants are dominant to tall plants. The genes controlling these two traits are on different chromosomes. You cross a true-breeding purple, short plant with a true-breeding white, tall plant and then intercross the resulting F1 offspring. In the F2 offspring, you find the following phenotypes: Purple, short Purple, tall 608 161 White, short White, tall 173 58 With your knowledge of the x' test, you will determine whether the outcomes of the F1 intercross corresponds to expectations based on Mendelian genetics. 1. What is your null hypothesis for the outcome of the F1 intercross? Write it here: 2. Based on your null hypothesis, how many individuals do you expect in each of the phenotypic classes? Write your expectations below. Purple, short Purple, tall White, short White, tall 3. What are the degrees of freedom for this test? Write your answer here:
You decide to cross two true-breeding stocks of pea plants. One parent has blue, axial flowers and the other has white, terminal flowers; all F1 individuals have blue, axial flowers. If you then cross the F1, amongst the F2 offspring, what is the probability of plants with white axial flowers? (Note: The genes for flower colour and location assort independently) O 1/16 O9/16 O 3/16 1/8 O 1/4
Sunflowers with small flowers measuring 10 cm in diameter are crossed with plants that have large flowers with a diameter of 16cm. All offspring in the F1 generation have medium size flowers with 13 cm in diameter. When crossing two F1 generation flowers, the F2 generation shows 4 flowers are 10 cm in diameter and 4 are 16 cm in diameter. Between these are 5 phenotypic classes with diameters intermediate to those at the extremes. What size flower makes up the most common phenotypic class?
A variety of pea plant known as Blue Pamlico produces a tall plant with blue seeds. A second variety of pea plant called Mulberry Dwarf produces a short plant with white seed. The two varieties are crossed and the seeds are collected. All the seeds are white. When planted, the seeds all produce tall plants. These tall plants are allowed to self-fertilize. For the F2 generation, 94 plants had blue seeds and were tall, 272 plants had white seeds and were tall, 31 plants had blue seeds and were short, and 89 plants had white seeds and were short. part a) Which phenotypes are dominant and why? part b) What would be the expected distribution of phenotypes in the F2 generation if the alleles of the genes assort independently? part c)Perform chi square analysis on the distribution of phenotypes in the F2 generation. ? part d ) Are these results consistent with the hypothesis of independent assortment?

A trait in garden peas involves the curling of leaves. A two-factorcross was made by crossing a plant with yellow pods and curlingleaves to a wild-type plant with green pods and normal leaves. AllF1 offspring had green pods and normal leaves. The F1 plants werethen crossed to plants with yellow pods and curling leaves. Thefollowing results were obtained: 117 green pods, normal leaves115 yellow pods, curling leaves78 green pods, curling leaves80 yellow pods, normal leavesA. Conduct a chi square analysis to determine if these two genesare linked.B. If they are linked, calculate the map distance between the twogenes. How accurate do you think this calculated distance is?
