Match List-I with List-II
| List-I | List-II | ||
| (a) | Haemophilia | (i) | Inborn error of metabolism which lacks an enzyme that converts phenylalanine into tyrosine |
| (b) | Down's Syndrome | (ii) | Sex-linked recessive disorder; a defect in blood coagulation |
| (c) | Phenylketonuria | (iii) | Presence of additional copy of X-chromosome (44+XXY) |
| (d) | Klinefelter's Syndrome | (iv) | Additional copy of chromosome number 21 |
Choose the correct answer from the options given below:
| (a) | (b) | (c) | (d) | |
| 1. | (ii) | (iv) | (i) | (iii) |
| 2. | (iv) | (ii) | (i) | (iii) |
| 3. | (ii) | (iii) | (i) | (iv) |
| 4 | (i) | (ii) | (iii) | (iv) |
| I: | Haemophilia is a sex-linked recessive disease. |
| II: | Down’s syndrome is due to aneuploidy. |
| III: | Phenylketonuria is an autosomal recessive gene disorder. |
| IV: | Sickle cell anaemia is an X-linked recessive gene disorder |
2. I, III and IV are correct
3. I, II and III are correct
4. I and IV are correct
Study the pedigree chart given below:
What does it show?
| 1. | Inheritance of a sex-linked inborn error of metabolism |
| 2. | Inheritance of a condition like phenylketonuria as an autosomal recessive trait |
| 3. | The pedigree chart is wrong as this is not possible |
| 4. | Inheritance of a recessive sex-linked disease like haemophilia |
If a female having gene for haemophilia and colour-blindness on one X-chromosome marries a normal male, then what are the chances in their offspring?
1. 50% sons diseased and 50% normal
2. All normal offspring
3. 100% daughters are carrier
4. 100% sons diseased
