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.
If they have a child what is the probability of their child having wet earwax?
The probability of a child having wet earwax depends on the genetics of the parents. Wet earwax is typically governed by a dominant allele, while dry earwax is recessive. If both parents have wet earwax (and are either homozygous or heterozygous), the child will likely inherit the wet earwax trait. However, if one parent has dry earwax, the probability varies based on the genetic makeup of both parents.
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 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.

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.
In humans normal color vision is dominant over colorblindness. A colorblind male marries a female who is a carrier for color blindness. What is the probability that a colorblind child would be born to?
The probability of a colorblind child being born is 50%. This is because the male passes his Y chromosome to all his sons, and since he is colorblind, his sons will inherit the colorblind gene from him. The daughters will inherit their X chromosome from the mother and have a 50% chance of being carriers like her.
How would a child inherit PKU?
A child inherits PKU if both parents are carriers of the gene mutation that causes the condition. When both parents are carriers, there is a 25% chance with each pregnancy that the child will inherit two copies of the mutated gene and have PKU.
