How can a child inherit a phenotype which neither of his parents have?

A phenotype is basically just the physical appearance of an individual. Inheritance is merely the transference of characteristics from one generation to another. When the pairs of chromosomes are pulled apart during meiosis, chance alone determines which member of each pair of chromosomes end up in the same cell. The possible combinations for humans (23 pairs of chromosomes) can be calculated to 2 to the 23rd power, or over 8 million different possible combinations in each sperm or ovum. The combinations possible in a zygote (fertilized egg) are greater that 70 000 000 000 000. As a result, its hard to find an exact duplicate for any one human being. When genes are transmitted from one generation to another, particular traits found in both parents can passed onto the child, expressed by dominant genes. A child can look physically different from either parent due to recessive gene traits carried by each parent. Recessive genes are present in the parents but remain "unseen".

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 are two visible characteristics that you inherit from your parents?
Two visible characteristics you inherit from your parents include your hair and eye color. These are directly determined by the genetic material passed down from each parent to the child.
What is the genotype of the offspring that do not share the parents phenotype?
Genotype is the coded for traitPhenotype is the visible characteristicSo in the case where both parents had heterozygous dominant Brown eyes (Bb - big B for brown, dominant gene; little b for blue recessive gene); it is possible for the child to have blue eyes, by being homozygous recessive (bb).However this is an educated guess, as your question does not make sense.
What type of DNA do daughters inherit from both parents but sons only inherit from mothers?
Daughters inherit an X-chromosome from each parent but sons receive an X-chromosome only from the mother. The father supplies a Y-chromosome to make the child a boy.
If AA is dominant for a widow's peak and if a child is born without a widow's peak what is his phenotype?
The Phenotype would be a straight hairline. The genotype would be aa.
Can two parents with blood type A positive have a child with O positive blood type?
Yes, if both parents have the genotype AO, then the child can have the O from both parents, phenotype O
Can a child be afflicted with a dominant trait if both her parents have a normal phenotype Why or why not?
YES SOMETIMES THAT IS NOT LIKELY.
Can a child have blue eyes when neither parents family have?
No.
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".
Can an adult child inherit a parents debt if there are no assets?
The estate will be responsible for the debts. A child is not responsible unless they co-signed for it.
What are two visible characteristics that you inherit from your parents?
Two visible characteristics you inherit from your parents include your hair and eye color. These are directly determined by the genetic material passed down from each parent to the child.
How will your child look?
it will probably inherit some genes from both parents, so it depends on which parent, but they usually resemble one of the parents, or both
If both parents are right handed can the child be left handed?
NO, the child would inherit the characteristics of both parents which will have the characteristics of the right handed, but they could if any of the parents families where left handed it can skip a generation and give it to the child. But mainly the child will inherit the characteristics of the right hand.
What is the genotype of the offspring that do not share the parents phenotype?
Genotype is the coded for traitPhenotype is the visible characteristicSo in the case where both parents had heterozygous dominant Brown eyes (Bb - big B for brown, dominant gene; little b for blue recessive gene); it is possible for the child to have blue eyes, by being homozygous recessive (bb).However this is an educated guess, as your question does not make sense.
What right as an adult adopted child when 1 parent dies?
When adopted you have the same rights as the biological children to inherit your parents.
What eye color will a baby have if bother parents have blue?
There is a high probably that the child would inherit blue eyes. But if the parents are also carries of other eye colour genes. They could inherit a different eye colour if both parents carry the same other colour gene.
Can two O neg people have an A plus baby?
NO. The alleles that lead to "O-type" blood are recessive to the alleles that lead to "A-type" blood and the child would have to inherit this "A" from one of his/her parents. Given that both parents are "O", there is nobody to inherit the "A" from. (This issue also presents with the exclusive RH- in the parents and RH+ in the child, because RH+ is dominant over the recessive RH-.)
