Options

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

Correct answer

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

Step-by-step solution

Linkage: Genes located close to each other on the same chromosome tend to be inherited together. Recombination: The formation of new combinations of alleles due to the exchange of genetic material. Crossing over: The physical exchange of genetic material between homologous chromosomes during meiosis. Genetic map: A diagram that shows the relative positions of genes on a chromosome.
