Explanation:
In order to determine the mode of inheritance for the given disease, we need to analyze the information provided. Let's break down the information and consider the possibilities:
1. The man and woman do not show any apparent signs of the disease.
2. Three out of seven sons suffer from the disease.
3. None of the daughters are affected.
Based on this information, we can rule out autosomal dominant and sex-linked dominant inheritance because in these cases, affected individuals would have at least one affected parent. Since both parents do not show any signs of the disease, these modes of inheritance can be excluded.
This leaves us with two possibilities: sex-limited recessive and sex-linked recessive inheritance. Let's analyze each one:
Sex-limited recessive inheritance:
- In this mode of inheritance, the trait is found only in one sex, either males or females.
- In the given scenario, the disease affects only the sons and none of the daughters.
- However, in sex-limited recessive inheritance, affected males would have carrier mothers.
- Since the information provided does not mention anything about the mother being a carrier, we can rule out sex-limited recessive inheritance.
Sex-linked recessive inheritance:
- In this mode of inheritance, the disease is carried on the X chromosome.
- Males have one X and one Y chromosome, while females have two X chromosomes.
- If an affected male has children, all his daughters will be carriers (because they inherit the affected X chromosome) but none of his sons will be affected (because they inherit the Y chromosome).
- In the given scenario, the daughters are not affected, which is consistent with sex-linked recessive inheritance.
- Additionally, since the disease affects three out of the five sons, it suggests that the mother is likely a carrier of the disease.
- Therefore, the mode of inheritance suggested for this disease is sex-linked recessive.
In conclusion, based on the given information, the most likely mode of inheritance for this disease is sex-linked recessive.
