Answer the following statement true (T) or false (F)
Before biologists discovered the role of DNA and chromosomes, Gregor Mendel, a scientific researcher, studied the genetics of pea plants related to flower colors, pea colors, pea pod shapes, and other features of the plant. He numerically modeled the results he observed and published results, which eventually led to our basic understanding of how biological traits are passed to new generations of organisms. His work, however, was largely rejected for over 30 years, partly for minor record-keeping errors, and partly for the new approach of defining reproduction of organisms in terms of numerical probabilities. This demonstrates that
A. only the most recent scientific investigations on a topic are useful in understanding biological conditions or processes. B. Gregor Mendel's work wasn't valid until researchers later identified chromosomes and their role in reproduction. C. a unique, new way to propose a theory discredits the research until someone else proves findings to be true. D. the color and shape of peas was not important to the scientific community. E. scientific evidence is harder to accept because of cultural biases and misunderstandings on the topic.
