Analyze the question stem

The question asks for the law or principle stating that an individual's two alleles for a gene separate during gamete formation.

Evaluate the options

• A. Principal of dominance: States that some alleles are dominant and others are recessive, where a dominant allele can mask a recessive one.
• B. Law of segregation: States that the two alleles for each gene separate (segregate) during gamete formation (meiosis), so that each gamete carries only one allele for each gene.
• C. Law of independent assortment: States that genes for different traits segregate independently of one another during gamete formation.
• D. Principal of true-breeding: Refers to organisms that produce offspring identical to themselves when self-pollinated, which is a descriptive term rather than a fundamental law of inheritance.

Determine the correct choice

The definition given in the prompt directly matches the Law of segregation.
