Q. No.Pedigree analysis is resorted to for genetic analysis in humans rather than conventional genetic methods because:
I. Choice matings are not possible
II. Number of progeny is limited
Of the two statements:
(1) Only I is correct
(2) Only II is correct
(3) Both I and II are correct
(4) Both I and II are incorrect
Which one of the following symbols and its representation, used in human pedigree analysis is correct?
(1) 
(2) 
(3) 
(4) 
Pedigree analysis is not utilized to trace
1. Specific trait
2. Sex ratio
3. Disease
4. Abnormality
Study the pedigree chart given below to identify the disorder
1.Sickle cell anaemia
2. Haemophilia
3. Myotonic dystrophy
4. Phenylketonuria
What does the given pedigree chart shows?
1. Sex-linked recessive trait
2. Sex-linked dominant trait
3. Inheritance of Sickle cell anaemia
4. Inheritance of autosomal dominant trait
Which one of the following symbols and its representation, used in the human pedigree analysis is correct?
| 1. |  = Mating between relatives |
| 2. |  = Unaffected male |
| 3. |  = Unaffected female |
| 4. |  = male affected |
Study the pedigree chart of a certain family given below and select the correct conclusion which can be drawn for the character:
| 1. | The parents could not have had a normal daughter for this character |
| 2. | The trait under study could not be colourblindness |
| 3. | The male parent is homozygous dominant |
| 4. | The female parent is heterozygous |
| 1. | Autosomal recessive | 2. | Autosomal dominant |
| 3. | Sex-linked recessive | 4. | Sex-linked dominant |
| 1. | The mating between I-1 and I-II is consanguineous |
| 2. | The first born child of I-1 and I-II is a male |
| 3. | The first born child of I-1 and I-II is a female |
| 4. | The first born child of I-1 and I-II is affected by a genetic disease |
