Explanation

Gregor Mendel is considered the father of modern genetics because he was the first to apply statistical methods and mathematical logic to biological inheritance.
Through his experiments with pea plants, he tracked inherited traits, counted the outcomes, and calculated precise mathematical ratios (like the 3:1 ratio for dominant to recessive traits).
This quantitative approach was a revolutionary shift, making it possible to convert biological observations into predictable, statistical data.

Option A: Charles Darwin's theory of evolution by natural selection was based on extensive observation and qualitative description, not statistical analysis of inheritance patterns.
Option C: Louis Pasteur was a pioneer in microbiology, known for the germ theory of disease, pasteurization, and vaccine development. His work was experimental but did not involve the statistical analysis of heredity.
Option D: Alexander Fleming discovered penicillin, the first antibiotic. His discovery was a result of observation and experimentation in microbiology, not genetics or biostatistics.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain History of Genetics and Biostatistics as background academic context rather than a clinical decision trigger.
Understanding Mendelian genetics is fundamental for nurses in many specialties. It allows them to comprehend the basis of hereditary diseases, educate patients and families about genetic risks, and interpret genetic screening results.
For example, a nurse in an obstetrics or pediatric clinic uses knowledge of dominant and recessive inheritance to explain to parents the chances of their child inheriting conditions like cystic fibrosis or sickle cell anemia.
What if? - If a patient has a family history of Huntington's disease (a dominant disorder), the nurse knows there is a 50% chance for each child of an affected parent to inherit the disease. This knowledge guides patient education and recommendations for genetic counseling.

How to Approach the Question

First, identify the core concept of the question: the integration of 'statistical analysis' with 'biological methods'.
Next, review the contributions of each historical figure listed in the options.
Charles Darwin is linked to evolution, Louis Pasteur to microbiology/germ theory, and Alexander Fleming to antibiotics.
Recall or deduce that Gregor Mendel is famous for his experiments with pea plants where he counted traits and established mathematical ratios, which is the definition of applying statistics to biology.
Select the option that directly matches the key concept. In this case, Mendel's work is the textbook example of biostatistics' origins.
