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.
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.
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.
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.
25% or 1 out of 4 (You can use a Punnett Square for that and/or other questions like it.)
50%, the Father's contribution decides the sex of a child.
50%
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.
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.
This means that the father has two copies of the dominant allele for a particular trait. As a result, all of his offspring will inherit at least one copy of the dominant allele from him. This implies that all his offspring will either express the dominant trait or be carriers of the dominant allele.
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 .
No. The baby must inherit one allele from each parent - therefore they must get either an A or B from the mother.
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.
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.
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.
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

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.
