The correct answer is:
P- (ii), Q - (i), R - (iii), S - (iv)
When an individual has more than two sets of chromosomes and both of which come from the same parental species is called autopolyploidy. It will be represented by AAAA.
Trisomy is a type of aneuploidy in which abnormal sets of chromosomes are present. The somatic cell contains three copies of one chromosome in trisomy and its genomic formula is 2n+1.
When an individual has more than two sets of chromosomes and both of which come from the different parental species is called allopolyploidy. It will be represented by AABB.
Nullisomy is also a type of aneuploidy in which diploid organisms lose a pair of homologous chromosomes and its genomic formula is 2n-2.
