Which law of Mendelian inheritance states that when two pairs of traits are combined in a hybrid, segregation of one pair of characters is independent of the other pair of characters?
Answer and explanation
Correct answer: C. Law of Independent Assortment
- Step 1: Mendel formulated three primary principles of inheritance based on plant breeding experiments.
- Step 2: The Law of Dominance explains the expression of only one parental trait in . The Law of Segregation (Purity of Gametes) states that allele pairs separate during gamete formation so each gamete receives only one allele.
- Step 3: The Law of Independent Assortment was derived from dihybrid crosses, stating that the alleles of two or more different genes assort independently into gametes during meiosis.
Answer
Law of Independent Assortment.
Why not the others: Law of Segregation describes the separation of alleles of a single gene locus; Law of Dominance describes the masking of recessive alleles by dominant ones in heterozygotes; Law of Unit Characters is an older descriptive concept.
