If a plant has yellow flowers and is crossed with a plant with red flowers and the resulting offspring has orange flowers, what can you infer about this plant's genetics?
- For a cross between a heterozygous tall pea plant and a dwarf plant, predict the ratios of genotypes and phenotypes in the offspring.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.Above is a pedigree chart for the family. What is the relation between the people in Row I and the people in Row ll?

What phenotypic ratio is produced from selfing it?b. What genotypic ratio is produced from selfing it?c. What phenotypic ratio is produced from testcrossingit?d. What genotypic ratio is produced from testcrossingitWith use of Punnett diagrams discuss how the results of experiments carried out by Austrian monk Gregor Mendel on pea plants brought aboutthe Law of Dominance, the Law of Segregation, and the Law of Independent assortment.
- What are the possible genotype and phenotype of offspring witha parent of two heterozygous tall pea plant? Legend: 1. Identify the genotypes of the parents 2. Complete the Punnett Square. 3. What are the possible genotypes of the offspring? 4. What is the genotypic ratio? 5. What are the possible phenotypes of the offspring? 6. What is the phenotypic ratio? 7. What is the probability of having short trait?A gardener performs a monohybrid cross on two heterozygous orange-fruited tomato plants. Plants expressing the recessive phenotype yield yellow tomato fruits. What percentage of the offspring will produce yellow tomatoes? A-075% B-50% C-100% D-25%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
