In Mendel’s experiments, the contrasting traits did not show any blending in:
| 1. | F1 stage |
| 2. | F2 stage |
| 3. | Both F1 and F2 stages |
| 4. | The statement is false as blending was seen at all stages |
| I: | F1 progeny of a monohybrid cross with complete dominance |
| II: | F2 progeny of a monohybrid cross with incomplete dominance |
The inheritance of flower colour in dog flower and 4’O clock plant exhibits:
| 1. | Complete dominance | 2. | Incomplete dominance |
| 3. | Co-dominance | 4. | Lethality |
In the case of co-dominance, the F1 generation resembles:
| 1. | Dominant parent | 2. | Recessive parent |
| 3. | Both the parents | 4. | None of the parents |
Blood group antigens are:
| 1. | Carbohydrates present in plasma |
| 2. | Carbohydrates present on the surface of RBCs |
| 3. | Plasma proteins |
| 4. | Proteins present on the surface of RBCs |
The inheritance of IA and IB allele exhibit:
| 1. | Complete dominance | 2. | Incomplete dominance |
| 3. | Co-dominance | 4. | Lethality |
The number of alleles, the genotypic combinations, and phenotypes in the ABO system are respectively:
| 1. | 3, 6 and 4 | 2. | 3, 4 and 6 |
| 3. | 2, 3 and 4 | 4. | 2, 3, and 6 |
What can the possible blood groups of progeny whose father and mother are of A and B blood groups, respectively?
| 1. | A and B only | 2. | AB only |
| 3. | All except O | 4. | A, B, AB, and O |
What can be the blood groups of progeny whose father and mother are of AB and O blood groups, respectively?
| 1. | A and B only | 2. | AB only |
| 3. | All except O | 4. | A, B, AB, and O |
