Conditions of a karyotype `2n pm 1 and 2n pm 2` are calledA. aneuploidyB. polyploidyC. allopolyploidyD. monosomy

Answer» Correct Answer - A
Aneuploidy involves changes in chromosome nimber by additions or delecitions of less than a whole set. In theis case organism gains of loser onr or more chromosomes but not a complete set. Palyploidy is defined as the addition of entire set of chromosome. The polyploidy can be triploidy (3n), teraploidy (4n), pentaploidy (5n), etc
Allopolyploidy is the polyploidy in which chromosome sets are non-homologous. In other words we can say that the allopolyploids are derived from a stock which is heterzygous. Monosomy is the process in which one chromosome is removed from diploid set of chromosome (2n-1).
