Answer 2

The disorder in humans with the following karyotype:

(a) 22 pairs of autosomes + XO = Turner’s syndrome

(b) 22 pairs of autosomes + 21 st chromosome + XY​ = Down syndrome

Turner syndrome is a genetic disorder found in females; this disorder is due to the complete or partial loss of one of the X chromosomes. Turner syndrome is also known as monosomy of the X chromosome.

Down syndrome is a chromosomal abnormality that is characterized by the presence of an extra copy of genetic material on the 21st chromosome .It can be either in whole (trisomy 21) or part (such as due to translocations).
