Which one of the following statements about polyploidy is correct?
Updated On: Feb 2, 2025
- Autopolyploids are derived from a single species
- Autopolyploids are derived from two different species
- Allopolyploids are derived from a single species
- Allopolyploids are not fertile when mated with each other
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Polyploidy involves an organism having multiple sets of chromosomes.
- Autopolyploids originate from chromosome duplication within a single species.
- Allopolyploids arise from hybridization between two species

Top Questions on Genetics
- Assertion (A): When the two genes in a dihybrid cross are situated on the same chromosome, the proportion of parental gene combinations is much higher than non-parental type.
Reason (R): Higher parental gene combinations can be attributed to crossing over between two genes. Study the cross given below:
Identify the abnormalities β1β and β2β in the offsprings of a cross done between a couple and distinguish between them.- Assertion (A): A bioreactor provides the optimal conditions for achieving the desired product by providing optimum growth conditions.
Reason (R): The most commonly used bioreactors are of stirring type. - Assertion (A): One of the properties of genetic code is degeneracy.
Reason (R): Some amino acids can be coded by more than one codon. Match the terms in Column-I with their description in Column-II and choose the correct option.
