With regard to the ABO blood types in humans, determine the genotype of the male parent and female parent shown here: Male parent: Blood type B; mother type O Female parent: Blood type A; father type B Predict the blood types of the offspring that this couple may have and the expected proportion of each.

Hi everyone. Welcome back. Let's look at our next problem. If the father has blood type A. With a. O. Genotype and the mother has blood type B. With B. O. Genotype, their offspring will have the following blood type. Well we can make a basic punnett square for this. We've been given the genotype of both parents. Were the father here he's Taipei is dominant over. Oh but we're given that his genotype has and oh alil mother has blood type B. As her phenotype. But her genotype is given as B. O. So when we look at the offspring we see we've got A B. In the square A. O. B. O. And then 00. So we've got three offspring that will express antigens on their cells. We've got A Type B. A. Type A. And type A. B. And then we've got another offspring that will be type O. Getting both those recessive genes. So our answer here is going to be all the possibilities. Choice D. Type A. A. B. B. And O. Those will all be possible with that particular combination of parents. See you in the next video
