A.
How does sexual reproduction ensure that all children in generation II inherit identical traits?

B.
How does the law of dominance prevent a dominant allele from being expressed in generation III?

C.
How does the law of segregation explain why an affected male in generation II passed the trait to the offspring?

D.
How does meiosis guarantee that offspring in generation III receive the same allele combinations from both parents?

The law of segregation (Mendel’s first law) explains that each parent’s two alleles separate during gamete formation so each gamete carries only one allele. That principle directly accounts for how an affected male in generation II could pass the trait to his offspring. The other choices are incorrect because sexual reproduction does not make siblings identical (A), the law of dominance does not “prevent” a dominant allele from being expressed (B), and meiosis does not guarantee offspring receive identical allele combinations from both parents (D).
