Triploidy

Verified step by step guidance

Understand the meaning of the term '3n' in genetics: it refers to an organism having three complete sets of chromosomes, where 'n' is the number of chromosomes in one set.

Recall that 'monosomy' refers to the loss of one chromosome from a pair, resulting in a chromosome number of 2n - 1, which is not the case here.

Recognize that 'trisomy' refers to the presence of an extra single chromosome (2n + 1), not an entire extra set of chromosomes.

Know that 'deletion' is a mutation involving the loss of a segment of a chromosome, not whole sets of chromosomes.

Conclude that having three complete sets of chromosomes (3n) is called 'triploidy', which is a type of polyploidy involving whole extra sets of chromosomes.
