Match List I with List II List I (Genetic disorders) List II (Type) (A). Thalassemia (I). X-monosomy (B). Turner's syndrome (II). Extra X-chromosome (C). Klinefelter's syndrome (III). 21 ^ st Trisomy (D). Down's syndrome (IV). Mendelian disorder Choose the correct answer from the options given below:

Step-by-step solution

Thalassemia is an autosomal recessive blood disorder, which is classified as a Mendelian disorder. Thus, (A) matches with (IV). Turner's syndrome is caused by the absence of one of the X chromosomes, resulting in a karyotype of 45 , X0, which is an X-monosomy. Thus, (B) matches with (I). Klinefelter's syndrome is caused by the presence of an additional copy of the X-chromosome, resulting in a karyotype of 47 , XXY. Thus, (C) matches with (II). Down's syndrome is caused by the presence of an additional copy of chrom
