Feature Characteristic A. Chromosome Y 1. Makes up a large portion of the genome, with non-coding functions B. SNPs (Single Nucleotide Polymorphisms) 2. Found in about 1.4 million locations in the human genome C. Chromosome 1 3. Contains the most genes among human chromosomes D. Repetitive sequences 4. Contains the fewest genes among human chromosomes

Options

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

Correct answer

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

Step-by-step solution

A - 4: Chromosome Y has the fewest genes. B - 2: SNPs occur in about 1.4 million locations in the human genome. C - 3: Chromosome 1 has the most genes among human chromosomes. D - 1: Repetitive sequences make up a large portion of the genome and have no direct coding functions.
