Mendel's law of segregation states that

Answer and explanation

Correct answer: A. the two alleles of a gene separate during gamete formation

  1. Step 1: Gregor Mendel analyzed the inheritance of discrete character traits through monohybrid crosses in garden peas.
  2. Step 2: The law of segregation establishes that the two alleles for a heritable trait separate from each other during gamete formation via meiosis.
  3. Step 3: Consequently, each gamete carries only one allele for each gene, and diploidy is restored upon random fertilization.
Answer
the two alleles of a gene separate during gamete formation.
Why not the others: genes are always inherited together describes complete genetic linkage, which violates independent assortment; alleles blend in the offspring describes blending inheritance, an obsolete theory disproved by Mendel's particulate inheritance; all traits are dominant contradicts Mendel's observation of recessive traits that reappear in the F2 generation.
