What is the probability that a male will inherit an X-linkedrecessive allele from his father?

∙ 13y ago
There is no possibility that a male will inherit and X-linked recessive allele from his father because for a male child the father only contributes the Y chromosome to his son (of the XY pair he has). If the fater's X chromosome has a recessive allele then it is 100% certain that he will pas this on to all his daughters.

What is the probability that certain genotypes and phenotypes will occur?
This depends entirely on the genotype of the parents. The probability of getting a specific genotype is the probability of getting the correct allele from mother (1/2) multiplied by the probability of getting the correct allele from father (1/2) multiplied by the number of ways this can occur. The probability of getting a phenotype, if the phenotype is dominant, is the sum of the probability of getting two dominant alleles, and the probability of getting one dominant allele. If the phenotype is recessive, the probability is equal to the probability of getting two recessive alleles.
What is the probability that a paternity test will be correct?
As part of a paternity test it includes a probability value to determine the probability that the man in question is biological father or not. If the probability value is 99.99% and the mother, child and man in question have all been tested then the man is the father. If it is less than that then the man is not the father. It is impossible to get a probability value of 100% unless every man in the world were tested. As it stands a paternity test is as accurate as its probability value. Therefore a paternity test with a probability value of 99.99% has a 99.99% chance of being correct. A paternity test is very accurate and does a great job of showing a childs genetic parents. The test is 99.9% accurate.
What does probability of paternity means?
Probability of paternity (POP) means how likely the man is to be the father. If the result is a 99% (or anything over 64, haha) POP I would say that he's the daddy.
What is the probability that a heterozygous father and a recessive mother with have offspring that are dominant?
25% or 1 out of 4 (You can use a Punnett Square for that and/or other questions like it.)
A woman has 5 children 1 girl and 4 boys What is the probability that her next child will be a girl?
50%, the Father's contribution decides the sex of a child.
What is the probability that a father produces a gamete with the allele for attached earlobes if he has one allele for detached earlobes and one allele for attached earlobes?
50%
If a mans father has a BBkk genotype for two particular genes and his mother has the BBkk genotype what will the mans genotype be?
BBkk as there is no other alleles present for the man to inherit. the father can only pass on a B allele and a k allele and the mother can also only pass on a B allele and a k allele.

If the phenotype is recessive, the probability is equal to the probability of getting two recessive alleles.
Does a human offspring inherit hemophilia from the mother or father?
Hemophilia is sex linked. Males inherit from their mother, daughters are carriers if the defective gene is inherited from one of either parent. A female must inherit two copies of the defective allele to have hemophilia .
Can an AB negative mother and an A positive father have an o positive baby?
No. The baby must inherit one allele from each parent - therefore they must get either an A or B from the mother.
If a brown eyed woman has a green eyed mother what is the brown eyed woman's genotype?
The mother's genotype is rr. The daughter would inherit one recessive allele from her mother because her mother has only recessive alleles. Because the daughter is green eyed, she would inherit a dominant allele from her father. The brown-eyed daughter's genotype would be Rr.
How do you find the possible genotypes of the children of a woman with blood type O and a man with blood type AB?
There are three alleles for blood type which can be represented by IA, IB, and i. A person with blood type O has the genotype ii. A person with blood type AB has genotype IAIB. If these two people produce children, those children will inherit one allele from each parent. They will therefore certainly inherit the i allele from their mother and either the IA or the IB from their father. The children with the genotype IAi will have type A blood, since the IA allele is dominant to the i allele. The children with the genotype IBi will have type B blood, since the IB allele is also dominant to the i allele.
What is the genotype of the father?
We can call these alleles. Each of us has two ABO blood type alleles, because we each inherit one blood type allele from our biological mother and one from our biological father.
Can A negative mother and A positive father have O negative child?
Yes, because the "O" allele is recessive paired with an "A" allele. IF both parents are heterozygous: A+O- and A-O- the there is a 1/4 chance that the child will inherit both alleles. As I am just a high school student I cannot offer any professional answer
Can a A negative mother o positive father have a a negative child?

What is probabilaty and how is it used in genetics?
Probabilaty, is actually spelled Probability. Probability is a number to be used to determine a chance of any occasion, such as a Coin-toss, with the probability being %50 of landing on heads/tails. Probability is used in genetics to determine the chance of a offspring having a mother(or father)'s trait. It is used with Punnet squares to determine the chance of a offspring having a parent's trait or allele combination.
What is am example of a dominant allele?
A dominant allele is the allele which expresses itself morphologically.for example;the dimple on your cheek.your mom has a dimple whereas your father doesn't have it .but you too possess it.then ,your mother's allele serves to be the dominant allele.
