Yes. If the father were BO+ and the mother were AO+, there is a 25% chance their child could be an O+.
If mother is heterozygote yes.
Yes. Your step-father is who he is to you because he married your mother. If you married his mother, you would be his step-father. Strange but true.
Yes, it is possible. The geneotype of the mother would be either BB or BO and for the father would be OO. If you cross the father's geneotype and either of the mother's then at least two of the four outcomes will be for B blood type. As for the - and +, positive is dominant over negative. The father could be + - or + + and the mother would be - -. Either combination would result in at least two positives. Therefore, it is possible for the mother to be B-, the father to be O+ and the baby to be B+. I added the link to the website where I got my info from. I want to know if an rh b neg blood type mother and an O positive father can have an A positive baby?

This is not possible, but if it were, the result would be no difference in anything.
Yes, it would be possible if the mother had type A blood.
Jacob syndrome, 49XYY, has to occur as a result of nondisjunction in the father. The Jacob Syndrome male would have received the X chromosome from his mother, and both Y chromosomes from the father (since the Y chromosomes can not possibly have come from the mother). Jacob Syndrome can be the result of nondisjunction in meiosis.
Yes, that is possible. It would also be possible for the child to be A+, O+, or O-, but no other blood types are possible.
If the father's Rh allele pattern is +-, he would be Rh+ but could still pass on the - allele to the child. Combined with an O- allele from the mother, the result would be an O- child.
That would be the father-in-law and the mother-in-law.
yes if the mother or father (or an ancestor) had red hair then it would be genetic
Since the father and mother each contribute half (23 chromosomes) of the genetic material needed to form a child (46 chromosomes), the brother and sister are equal in terms of biological similarity, no matter if they had a different mother (same father) or father (same mother). However, if any of the father/mother pairs are related, the result is skewed.
