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).

The table given below shows the Lod score values of three different pairs of genes studied for assessing if they are linked pairs:
Gene Pair '1' Gene Pair '2' Gene Pair '3' Lod Score 1 2 3 The following conclusions were made from the data given above:
A. For gene pair 1 the probability of the genes being linked is 10 times more likely than them assorting independently.
B. For gene pair 2, the Lod score 2 indicates that the probability of the genes being linked is twice more likely than assorting independently.
C. The genes of pair 1 and 2, can both be considered as linked, while the genes of pair 3 exhibits independent assortment.
D. The genes of pair 3 can be considered as linked.
