Gregor Mendel was a critical contributor to our understanding of inheritance today. In his experiments he tracked seven visual traits of pea plants and ensured that they produced offspring identical to themselves. What are the terms that we used to identify two separate factors?*1 pointgenotype; true breedinggenotype; cross breedingphenotype; true breedingphenotype; cross breeding

A scientist was carrying out some of Mendel's experiments and wanted to understand how seed colour in peas was inherited. The scientist crossed a yellow heterozygous plant with a green homozygous plant.Determine the genotypes of the parent plants.

One of the reasons that Mendel was able to discover the basic principles of genetics using pea plants is because pea plantsMultiple choice question.produce only a small amount of offspring each generation.develop slowly.exhibit traits in forms that are blended and that differ from either parental trait.self-fertilize and cross-fertilize.

One of the reasons that Mendel was able to discover the basic principles of genetics using pea plants is because pea plants ______.

In 1866, Mendel published three main conclusions to his findings. Which of the following ideas was not proposed by Mendel?Characteristics are determined by hereditary unitsHereditary units are organised in chromosomesHereditary units can be dominant or recessive Hereditary units are passed on unchanged by both parents3The height of Mendel’s pea plants is controlled by a single gene with two alleles: a dominant tall allele (T) and a recessive short allele (t). In a series of F1 crosses involving one homozygous tall plant (TT) and one short plant (tt), 400 F2 offspring were produced. Approximately how many of these offspring would you expect to be short?200Zero4001004In a series of crosses involving pea plants heterozygous for the height gene, 800 offspring are produced. Approximately how many of these offspring would you expect to be tall?8002006004005Mendel’s investigations were ‘reproducible’. What is meant by this term?The pea plants could be reproducedThe investigations could be repeated by different researchers with different resultsMendel reproduced his own investigations with the same results on numerous occasionsThe investigations could be repeated by different researchers with the same results

Sometimes, when Mendel crossed two pea plants with each other, he obtained a phenotypic ratio of 3:1 purple-flowered pea plants to white-flowered pea plants. These results are consistent with which set of parents?Multiple ChoiceHomozygous purple pea plant and homozygous white pea plantHeterozygous purple pea plant and homozygous purple pea plantHeterozygous purple pea plant and homozygous white pea plantHeterozygous purple pea plant and heterozygous purple pea plant
