Solution
(i) Alignment is correct
(ii) No of chromosomes 2n+1+1 where n =12 with double trisomy
(iii) Type diploid
(iv) Aneuploid
(v) Monosomic for no chromosome
(vi) chromosome no. 1 and 3 would form trivalent during cell division
(vii) Number of chromosome in metaphase and anaphase of mitosis = 52 chromosomes
{2x[(2x12)+2]}
(viii) Yes, there are deletions in Chr9 and Chr10
(ix) Yes, there is inversion in the X-Chromosome
(x) Chr11 is telocentric
(xi) This karyotype belongs to a male. Presence of XY
(xii) Number of Chromosomes found in gametes: The segregation of trisomic chromosomes is
not even. The trisomic chromosome may lead some gametes to have two chromosomes while
some have a single chromosome. In the present case with double trisomy, the gametes may have
either 12, 13, or 14 chromosomes.
(xiii) Bar body would be absent.
(xiv) 26 Chromosome would be found in the somatic cells.
