Understand that in genetics, the term 'ploidy' refers to the number of sets of chromosomes in a cell.
Recall that a diploid cell contains two complete sets of chromosomes, one from each parent.
Recognize that the standard abbreviation for a diploid cell is \$2n$, where $n$ represents one set of chromosomes.
Note that \(n\) or \$1n$ indicates a haploid cell, which has only one set of chromosomes, typical of gametes.
Understand that \$4n$ would indicate a tetraploid cell, which has four sets of chromosomes, not typical for normal diploid cells.
