Which of the following best describes Mendel's approach to studying genetics?
He used modern molecular techniques to study the structure of DNA
He conducted observational studies of plants in their natural environment
He used a controlled breeding program to study patterns of inheritance
He analyzed large datasets of genetic information from diverse species
Mendel's approach to studying genetics was based on controlled breeding experiments with pea plants. He deliberately crossed different strains of pea plants and observed the traits of their offspring. By carefully controlling the breeding process and recording the characteristics of the offspring, Mendel was able to discover the basic principles of inheritance, including the concepts of dominant and recessive traits and the idea that traits are inherited independently of each other. Mendel's approach was empirical and experimental, rather than based on observational studies or analysis of genetic data from diverse species. While Mendel's work predated the discovery of DNA, his approach to studying inheritance through careful observation and experimentation laid the groundwork for modern genetics research.
Option 3 is the correct answer.
