The question is incomplete as it does not have the options which are:
aneuploids
allopolyploids
amphipolyploids
autopolyploids
Answer:
Autopolyploids
Explanation:
Autopolyploid refers to the ploidy condition in organisms in which the ploidy level of organism increases that is multiple set of a single chromosome is formed in tissues.
The autopolyploids condition is observed more frequently in the plants than the animals when the tissue cells divide. In the given question, the chromosome number increases or double that is from 18 to 36 to 54, 72 and 90. This shows that the ploidy level is increasing.
Thus, Autopolyploids is correct.
