Concept Description A. Law of Independent Assortment 1. Genes for different traits assort independently of one another. B. Linkage 2. Exchange of genetic material between homologous chromosomes during meiosis. C. Recombination 3. Genes located close together on the same chromosome tend to be inherited together. D. Complete Dominance 4. One allele completely masks the expression of another.

Options

  1. AA - 3, B - 4, C - 1, D - 2
  2. BA - 2, B - 1, C - 4, D - 3
  3. CA - 4, B - 3, C - 2, D - 1
  4. DA - 1, B - 3, C - 2, D - 4

Correct answer

D. A - 1, B - 3, C - 2, D - 4

Step-by-step solution

Law of Independent Assortment: Genes for different traits assort independently during gamete formation. Linkage: Genes located close together on the same chromosome are inherited together. Recombination: Genetic material is exchanged during meiosis, leading to variation. Complete Dominance: The dominant allele masks the recessive allele in the phenotype.
