How can doctors and genetic counselors calculate the probability of a child inheriting a disease?
the punnett square
How is probability used in biology?
It's used commonly to estimate the traits of a child of two parents. For example, the probability of the child having blue eyes, or curly hair, or even having genetic disease.
What is the probability that a couples first child will be a female?
There is no simple answer to the question because the children's genders are not independent events. They depend on the parents' ages and their genes.However, if you assume that children's genders are independent events then, given that the probability of a girl is approx 0.48.
What is the probability that the 6 child family has exactly two girls?
The probability is 2 - 6
What is the probability of a child being a boy?
It depends on the context: if you select a child at random from a girls' school, the probability is 0, while if it is at a boys' school it is 1!
What is the probability of a man who has BB genotype and his wife who has BO genotype to have a child who is AB?
No probability. Neither parent has an "A" for the child to inherit to make an "AB".
What does a child have to inherit to have an autosomal disease?
Bad luck?
A man in 30s has 3 children discovers that his mother has Huntington disease his father is unaffected. What is probability that his first child will develop Huntington's?
That depends on whether the man in his 30s inherited HD from his mother. If he did not, the chances are zero. If he did, the chances are 50-50 for each child that they will inherit from him.

How would a child inherit PKU?
PKU is a genetic disease, caused by an inability to metabolize the amino acid phenylalanine.

If an individual expresses a dominant disease will the children always inherit the disease?
Not always. It depends if the individual is a hybrid- meaning they have both the dominant and the recessive gene. They can pass on the recessive gene instead of the dominant one, and assuming the other parents also passes on the recessive gene, the child will not inherit the disease.
A man and a woman who do not have cystic fibrosis get married have two children who have the disease they want to try and have a third childwhat is the probability of the third having the disease?
same probable as the first child having it. By doing the punnet square, they are both recessive for the disease. There is a 25% chance that the child will get the disease.

What is the probability of a baby inheriting a disease from parents?
For the case where the disease is a recessive trait (more likely), the probability is 1/2 that they will carry the diseased gene but not show it. If the disease is a dominant trait, the probability is 1/2 that they will get it and show it. Having said that, in the recessive case, if both parents are carriers, then there is a 1/4 case the child will get it from both and then show the disease. I have answered regarding genetically-transmitted diseases. Mental illness and other forms of "disease" will be different.
How does someone inherit canavan disease?
Both the father and mother of a child have to carry a mutation in the ASPA gene in order for the child to inherit Canavan disease. If both parents are carriers, each naturally conceived child has a 25% chance of having Canavan. Although most common in people of Ashkenazi Jewish descent, there are upwards of 70 mutations of the gene that have been identified so far, and they can occur in individuals from any ethnic background.
Why is huntingtons disease more common than other serious dominant genetic disorders?
Huntingtons is a genetically inherited disease from a parent. when chromosomes are passed onto a child, the child wont always receive the chromosome containing the gene. But, if they do inherit the gene they will have the disease no matter what, because the disease is dominant. If it was recessive, the child could inherit the disease but not necessarily get the disease.
