Multiple Choice

Mendel formed a possible explanation for the outcomes he observed in pea plants. Mendel formed a:

hypothesis about how traits are inherited

theory that all traits blend together in offspring

law stating that environmental factors solely determine traits

model suggesting that traits skip every generation

Verified step by step guidance

Understand the context of Mendel's work: Mendel conducted experiments on pea plants to observe how traits are passed from one generation to the next.

Recall the definitions of key scientific terms: A hypothesis is a proposed explanation based on observations; a theory is a well-substantiated explanation; a law describes consistent natural phenomena; a model is a simplified representation.

Analyze Mendel's contribution: He proposed an explanation for the patterns he observed, specifically how traits are inherited through discrete units (now called genes).

Recognize that Mendel's explanation was a hypothesis because it was an initial idea formed to explain his experimental results before being widely tested and accepted.

Conclude that Mendel formed a hypothesis about how traits are inherited, rather than a theory, law, or model as described in the other options.
