What else can I help you with?
A woman and her husband both show the normal phenotype for pigmentation but both had one parent who was an albino what is the probability that their first child will be an albino?
25%
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.
A woman is chosen at random among all woman who have two children She is asked if she has at least one son and says yes. What is the probability of here other child being a boy?
Children's genders are not independent and therefore there is no simple answer. However, if you do assume that their genders are independent then the probability is 1/3.
How can you relate probability and punnett squares?
The probability of an event is easily calculated by dividing the number of squares that predict the event by the total number of squares. For example, if a man and woman were having a child, and the man was tall with brown hair and the woman short with blonde hair, the probability of the child being, say, tall with blonde hair, would be 1(number of squares with tall/blonde as a result) divided by 4(total number of squares), which is .25, or 25%
If a woman has given birth to two sons what is the probability that her third child will be a girl?
In general, the probability that any child will be a girl is approximately 1 in 2. It is like flipping a coin. There is a 50-50 chance for a specific outcome each time. It would be less likely that a woman would have three sons than that she have two sons and one daughter, but each individual outcome is a 50-50 chance. If this is a brain teaser, since we are given that the woman has given birth to two sons, it could imply that any other children she has are daughters, in which case the probability is 100% - if we know that she has other children.
Man with blood type B marries a woman with blood type A and their child is blood type O what is the porbabtility their next child will be blood type AB or B?
The probability of their next child being blood type AB is 0% because neither parent carries the AB blood type. The probability of their next child being blood type B is 25% because the father carries the B allele, which can be passed on to the child.

There is a 25% chance that their first child will have type O blood if both parents are heterozygous for blood type A and B. This is because the child could inherit an O gene from each parent, resulting in blood type O.
