Laws Description A. Law of Dominance 1. Two alleles segregate during gamete formation. B. Law of Segregation 2. One allele masks the expression of another. C. Law of Independent Assortment 3. Alleles of different genes assort independently. D. Chromosomal Theory of Inheritance 4. Genetic inheritance patterns are determined by chromosomes' behavior during meiosis

Options

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

Correct answer

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

Step-by-step solution

Law of Dominance: One allele dominates over another in heterozygous condition. Law of Segregation: Alleles segregate during gamete formation. Law of Independent Assortment: Genes for different traits assort independently. Principle of Uniformity: F1 offspring resembles the dominant parent.
