The mode of inheritance of the trait shown in the following pedigree is most likely:
| 1. | Autosomal recessive | 2. | Sex-linked recessive |
| 3. | Autosomal dominant | 4. | Sex-linked dominant |
The inheritance of the trait shown in the given pedigree most likely is:
| 1. | Autosomal recessive | 2. | Autosomal dominant |
| 3. | Sex-linked recessive | 4. | Sex-linked dominant |
In the pedigree shown, mating between individuals III 2 and III 3 results in a progeny, which is an affected female. Based on this information, most likely this disorder is:
| 1. | Holandric | 2. | Sex-linked dominant |
| 3. | Sex-linked recessive | 4. | Either 1 or 2 |
A human female who is not color blind but whose father was color blind marries a normal male. What proportion of their male progeny will have red-green color blindness?
| 1. | 75% | 2. | 50% |
| 3. | 25% | 4. | 0% |
The pedigree shows the inheritance of red-green color blindness in a family. If II 3 marries a color-blind man, what is the probability that her first child will be normal?
| 1. | ¼ | 2. | ½ |
| 3. | 2/3 | 4. | ¾ |
