Genetic Disorder Matching Solution
This question requires matching genetic conditions from List - I with their corresponding descriptions or chromosomal abnormalities in List - II.
Matching Breakdown:
- (a) Klinefelter Syndrome: This condition occurs in males due to an extra X chromosome, resulting in a **XXY** chromosomal makeup. It matches with (ii) xxy.
- (b) Turner Syndrome: This condition affects females and is characterized by the absence of one X chromosome, leading to a **XO** chromosomal makeup. It matches with (iii) xo.
- (c) Down Syndrome: Commonly known as **Trisomy 21**, this genetic disorder results from an extra copy of chromosome 21. It matches with (i) trisomy 21.
- (d) Phenylketonuria (PKU): This is an inherited metabolic disorder where the body cannot properly break down an amino acid called phenylalanine. It matches with (v) Inability to metabolize amino acid.
Final Matches:
Based on the analysis:
- (a) matches with (ii)
- (b) matches with (iii)
- (c) matches with (i)
- (d) matches with (v)
Therefore, the correct combination is (a)-(ii), (b)-(iii), (c)-(i), (d)-(v).
