Question

Addition of one or more haploid set of its own genome in an organism results in

• A. Autopolyploidy
• B. Allopolyploidy
• C. Aneuploidy
• D. Diploid

Answer 1

The correct option is A Autopolyploidy

Autopolyploidy is the phenomenon in which nucleus contains additional one or more haploid set of its own genome apart from normal number of chromosomes. Allopolyploidy is the phenomenon in which nucleus contains chromosomes from more than the required number of species. Aneuploidy is the presence of an abnormal number of chromosomes in nucleus. For example, human cell having 45 or 47 chromosomes instead of 46 chromosomes.. Diploid cells are cells containing two complete sets of chromosomes.

Thus, the correct answer is option A.
