Question

Polyploidy can result from

• A. double fertilization
• B. polyspermy
• C. diploid gametes
• D. all of the above

Answer 1

The correct option is D all of the above

Polyploidy is the state of a cell or organism having more than two paired sets of chromosomes.

Double fertilization results in the triploid zygote. Polyspermy describes an egg that has been fertilized by more than one sperm. This will result in an extra set of chromosomes. When a diploid gamete fuses with a haploid gamete, a triploid zygote forms, which is also a case of polyploidy.

So, the correct option is 'all of the above'.
