Yes, if both parents wear glasses, it is more likely that their child will also need glasses due to the genetic predisposition for vision problems.
The child would most likely be ab plus but she/he could also be a or b.
A recessive trait can only be passed along if both parents carry at least one of the recessive genes to the child. If both parents manifest the trait (that is, if both parents have both recessive genes), then the child will manifest (that is, carry both recessive genes and display) the recessive trait. If one parent manifests and the other parent only carries the trait (that is, carries one dominant and one recessive gene) then the child will definitely carry and have a 50% chance of manifesting. If both parents carry the recessive, the child is 25% likely not to carry the trait at all, 50% likely to carry and 25% likely to manifest the trait.
A child with both parents dead
The child's blood type is determined by his or her parents' blood types. If both parents have type A, the child can have either type A or O. If both parents have type B, the child can have either type B or O. If one parent has type A and the other parent has type B, the child can have type A, B, AB, or O, but he/she is most likely to have type AB. If both parents have type O, the child will have type O.
Probably quite likely; but not always
Not if she is a suitable parent. The child have the right to both parents so shared custody is most likely.
No, a child cannot be afflicted with a dominant trait if both parents have a normal phenotype. This is because dominant traits require at least one copy of the dominant allele to be expressed, and if both parents have a normal phenotype, they would not carry the dominant allele to pass onto their child.
The child shares both the parents' genetic susceptibility to cancer as well as any environmental factors (diet, exposure to carcinogens in the home/community, etc.).
Can parents with both negative blood have a child and how much of a chance for that child having a dissabillity
No. If both parents are type O, the child will be O. If both are A, the child can be either A or O. If both are B, the child can be either B or O. If both are AB, the child can be A, B, or AB (but not O).
When a recessive trait is inherited from both parents, it will be expressed. If the trait is hemophilia, the child will be a hemophiliac.
