Question

Парагемофилия (склонность к кожным и носовым кровотечениям, сильные кровоте-чения при мелких травмах) наследуется как рецессивный аутосомный признак. Какова вероятность рождения детей с этой аномалией в семье, где оба супруга страдают параге-мофилией?

Answer 3

Paragmophilia Inheritance and Probability of Children with the Anomaly

Paragmophilia, a tendency towards skin and nasal bleeding, with severe bleeding from minor injuries, is inherited as a recessive autosomal trait. Let's calculate the probability of having children with this anomaly in a family where both spouses suffer from paragmophilia.

The inheritance pattern for a recessive autosomal trait is as follows: - If both parents are carriers of the recessive allele, there is a 25% chance with each pregnancy that the child will inherit two copies of the recessive allele and express the trait. - There is a 50% chance that the child will be a carrier like the parents. - There is a 25% chance that the child will inherit two normal alleles and not express the trait.

Therefore, in a family where both spouses suffer from paragmophilia, the probability of having children with this anomaly is: - 25% for each child to inherit two copies of the recessive allele and express the trait. - 50% for each child to be a carrier like the parents. - 25% for each child to inherit two normal alleles and not express the trait.

These probabilities are based on the principles of Mendelian genetics and the specific inheritance pattern of a recessive autosomal trait.
