What term describes a cell containing two sets of chromosomes (2n), one set inherited from each parent?

• A. Haploid
• B. Diploid Cell
• C. Karyotype
• D. Gene Mutation

Answer: (B)

A cell with two complete sets of chromosomes, one from each parent, is a diploid cell. This means there are two homologous copies of each chromosome, typically one maternal and one paternal, which is why somatic (body) cells in humans and many organisms are diploid. The notation 2n is used to indicate this diploid state; in humans, 2n equals 46 chromosomes arranged as 23 pairs. By contrast, a haploid cell has only one set of chromosomes (n), as seen in gametes like eggs and sperm. A karyotype describes the organized image of all the chromosomes in a cell, useful for counting and identifying structure, but it doesn’t define whether the cell is diploid or haploid. A gene mutation is a change in the DNA sequence itself, not the number of chromosome sets. So, the term that describes a cell containing two sets of chromosomes is diploid cell.
