During gamete formation, segregating unit factors assort independently of each other; this is described by which law?

• A. Mendel's law of segregation
• B. Punnett square
• C. Linkage
• D. Mendel's law of independent assortment

Answer: (D)

During gamete formation, the way different genes' alleles separate into gametes is described by Mendel's law of independent assortment. This principle says that the alleles for separate genes segregate into gametes independently of one another, producing new combinations of traits in offspring. The basis is the random orientation of chromosome pairs during meiosis, so the assortment of one gene’s allele into a gamete doesn’t depend on which allele is chosen for another gene, provided the genes are on different chromosomes or far apart on the same chromosome. This is distinct from the law of segregation, which deals with the separation of alleles for a single gene into gametes. A Punnett square is a predictive tool, not a law, and linkage describes genes that are close together on the same chromosome and tend to be inherited together, which actually reduces independent assortment.
