Question

Перед судово-медичною експертизою поставлено завдання з'ясувати, чи с хлопчик котрий живе в сім' N, рідним чи прийомним сином. Відомо, що жінка мас нормальний зір та легку форму таласемії, її чоловік дальтонік з легкою формою таласемії. Син же не має обох аномалій. Таласемія спадкується як аутосомно- домінантна ознака: у гомозигот важка, у гетерозигот легка форма, ген дальтонізму (d) рецесивний, зчеплений з Х-хромосомою. ОЧЕНЬ СРОЧНО!!! ДАЮ 60 БАЛЛОВ

Background Information

To determine whether the boy living in the family is the biological or adoptive son, a forensic medical examination has been requested. The woman has normal vision and a mild form of thalassemia, while her husband is color blind and also has a mild form of thalassemia. The son, however, does not have either of these anomalies. Thalassemia is inherited as an autosomal dominant trait, with severe form in homozygotes and mild form in heterozygotes. The gene for color blindness (d) is recessive and linked to the X chromosome.

Analysis

Based on the given information, we can analyze the inheritance patterns of thalassemia and color blindness to determine the likelihood of the boy being the biological or adoptive son.

1. Thalassemia Inheritance: - Thalassemia is inherited as an autosomal dominant trait. - Homozygotes (TT) have a severe form of thalassemia. - Heterozygotes (Tt) have a mild form of thalassemia. - The son does not have thalassemia, indicating that he does not have two copies of the thalassemia gene (TT). - Therefore, it is possible that the son is not the biological child of the couple, as at least one of the parents should have the thalassemia gene for the son to inherit it.

2. Color Blindness Inheritance: - Color blindness is a recessive trait linked to the X chromosome. - Males have one X chromosome and one Y chromosome, while females have two X chromosomes. - The gene for color blindness (d) is recessive, meaning that individuals need two copies of the gene (dd) to express the trait. - The husband is color blind, indicating that he has two copies of the color blindness gene (dd). - The son does not have color blindness, indicating that he does not have two copies of the color blindness gene (dd). - Since the son does not have color blindness, it is unlikely that he is the biological son of the husband.

Conclusion

Based on the analysis of the inheritance patterns of thalassemia and color blindness, it is unlikely that the boy is the biological son of the couple. The absence of thalassemia in the son suggests that at least one of the parents should have the thalassemia gene, while the absence of color blindness in the son suggests that the husband should have passed on the color blindness gene. However, it is important to note that this analysis is based solely on the given information and a comprehensive genetic analysis would be required for a definitive conclusion.

Please consult a medical professional or genetic counselor for a more accurate assessment of the situation.
