Match the column A B (i) Mendelian traits (a) α and β (ii) Haemophilia (b) Colour blind (iii) Haemoglobin (c) Cooley's anemia (iv) Thalassaemia (d) Blood clot (e) Monogenic

(i) Mendelian traits- (e) Monogenic- Monogenic inheritance refers to the inheritance that is controlled by the alleles for one particular locus. These traits are inherited according to Mendel's Laws. (ii) Haemophilia- (d) Blood clots- Haemophilia is a disorder in which blood does not clot normally. (iii) Haemoglobin- (a) α and β - Haemoglobin subunit beta, ( β -globin) is a globin protein, coded for by the HBB gene, which along with alpha globin (HBA), makes up the haemoglobin in adult humans. (iv) Thalassaemia major- (c) Cooley's anemia- This is the most severe form of beta thalassaemia in which the patients completely lack beta protein in the haemoglobin causing a life-threatening anemia. Hence, the correct match are as follows: A B (i) Mendelian traits (e) Monogenic (ii) Haemophilia (d) Blood clot (iii) Haemoglobin (a) α and β (iv) Thalassaemia major (c) Cooley's anemia
