B
False
Verified step by step guidance1
Understand the definitions: Aneuploids are organisms with an abnormal number of chromosomes, typically missing or having extra chromosomes. Polyploids have more than two complete sets of chromosomes.
Consider the effects of aneuploidy: Aneuploidy often leads to significant developmental abnormalities because the balance of gene expression is disrupted.
Consider the effects of polyploidy: Polyploidy can sometimes be tolerated in organisms, especially plants, and may not result in as severe abnormalities as aneuploidy.
Compare the severity: Aneuploidy tends to cause more severe abnormalities than polyploidy due to the imbalance in chromosome number affecting gene dosage.
Conclude based on comparison: Given the definitions and effects, aneuploids are generally considered more abnormal than polyploids.
