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).

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.

ne of the traits that Mendel studied in pea plants is plant height. Tall plants are dominant with respect to dwarf plants. If the gene for this trait is denoted by the letter T, then the genotype of a dwarf pea plant is
