Sally has blood type B and has a child with blood type O. In a paternity test which blood type would exclude a man as the father of the child? Group of answer choices - O - Only A - A or B - Only AB - Only B
Show the complete solution including the Punnett Sq. Lina has dimples, freckles, and a widow’s peak. She is a heterozygous for all of the three traits. David, her husband also has freckles and dimples but has a continuous hairline. As freckle is known to be dominant over none, dimples are dominant over no dimples, and widow’s peak is dominant over continuous hairline, what is the a) Probability that their child will have three recessiveness: no freckle, no dimples, and has widow’s peak; and b) Probability that their child will have the same phenotype as Lina (with freckles, dimples, and widow’s peak)? Legend: Ff – freckles Dd – dimples Ww – widow’s peak

A male with B blood and a female with O blood are expecting a child together. Determine all possible blood types for their offspring. Drawing Punnett squares (2 X 2) as you do this will help. (Remember that blood types A and B can have 2 different genotypes and you need to take this into account in setting up your Punnett squares.) Possible ABO blood types:______________________ If both of these individuals have Rh+ blood, is there any way they could produce a child with Rh- blood? (Be sure to consider the genotypes for Rh + individuals.) Explain your answer.
