Chromosomal Abnormalities: Match the Column

Correct Answer: 1-f, 2-e, 3-d, 4-c, 5-b, 6-a

From the notes (Mutation section):

• 1. Euploidy (f): Change in number of SETS of chromosomes (e.g., monoploidy, triploidy, tetraploidy)
• 2. Aneuploidy (e): Change in number of chromosomes IN a set (e.g., monosomy 2N−1, trisomy 2N+1)
• 3. Monosomy (d): 2N − 1 (loss of one chromosome from a pair)
• 4. Nullisomy (c): 2N − 2 (loss of a complete pair of homologous chromosomes)
• 5. Monoploidy (b): 2N − N (loss of one complete haploid set)
• 6. Triploidy (a): 2N + N (addition of one complete haploid set)

Both Euploidy and Aneuploidy are types of Heteroploidy (Chromosomal Mutation)
