Suppose Mendel had transferred pollen from an F1 plant to the carpel of a plant that was homozygous recessive for both genes. Set up the cross and draw Punnett squares that predict the offspring for both hypotheses. Would this cross have supported the hypothesis of independent assortment equally well?

Mendel also studied tall and short varieties of pea plants. When he crossed tall x short plants together, the F1were tall. The tall F1 plants were self-hybridized to produce the F2. What proportion of phenotypes would be expected in the F2? 1:2:1 tall:intermediate:short 3:1 tall:short 1:1 tall:short 3:1 short:tall 1:2:1 intermediate:tall:short
Mendel crossed homozygous plants with green seeds with homozygous plants with yellow seeds and found what all offspring were yellow construct a genetic diagram to show f1 and f2 generation
What evidence in PEa plant crosses supported Mendels law of independent assortment
For a cross between a heterozygous tall pea plant and a dwarf plant, predict the ratios of genotypes and phenotypes in the offspring.
Mendel performed crosses in which he used pollen from a white-flowered plant to fertilize a purple-flowered plant and pollen from a purple-flowered plant to fertilize a white-flowered plant, showing the same results with both. What did these reciprocal crosses demonstrate? A. That the plants were not sterile. B. That there was no epistasis. C. That the trait could be passed from either parent. D. B and C.
In the same cross as question #1, what fraction of the offspring will have their father's genotype for both traits?
Which evidence supports Mendel’s law of independent assortment? A. In a monohybrid cross, both traits appear in the offspring. B. In a monohybrid cross, only the dominant traits appear in the offspring. C. In a dihybrid cross, only the dominant traits appear in the offspring. D. In a dihybrid cross, all four traits appear in all combinations in the offspring.
Why did Mendel perform "reciprocal crosses"? Someone gives you a bag of yellow peas and you plant them in the Spring. Can you predict the color of the peas that will appear in the pods on the plants grown from these peas? Would your answer be different if you had received a bag of green peas? Explain what Mendel means when he writes that the 3:1 ratio observed in the first generation from the hybrids "resolves itself" into a ratio of 2:1:1
Based on the data, which trait do you think is dominant versus recessive? Explain the information you used to help you determine this. Based on your answer, how would you write the genotypes of the original parental generation for this cross?
Are there plant characteristics not covered by Mendelian principles? Cite examples to support your answer. In plants, is it possible that offspring become taller than the parents? Support your answer by making a cross.
