Describe the experimental design Mendel used while researching pea plant traits and explain the general result that lead him to form his hypothesis about the transmission of "factors" from parents to offspring?
What will be an ideal response?
Mendel chose pea parental plants that each had a different distinguishing characteristic, called a trait. For example, Mendel bred tall pea plants with short pea plants. Plant height is the trait in this case and has two variations: tall and short. He also bred plants carrying green seeds with plants having yellow seeds. In this work, seed color is the trait; green and yellow are the variations of the trait he studied. In these breeding experiments, he wanted to see how traits such as height and seed color were passed from generation to generation. Mendel kept careful records of the number and type of traits present in each generation. He also recorded the number of individual plants that carried each trait. He discovered patterns in the way traits were passed from parent to offspring through several generations. Based on those patterns, Mendel concluded that traits such as plant height and seed color are passed from generation to generation by "factors" that are transmitted from parent to offspring.
