If two parents are heterozygous for type A blood, what is the p probability that the offspring would have type O blood? 75% 25% 100% 50%

To determine the probability of an offspring having type O blood when both parents are heterozygous for type A blood, we can use a Punnett square. Let's represent the alleles for blood type as follows:- A (dominant allele for type A blood)- O (recessive allele for type O blood)Since both parents are heterozygous for type A blood, their genotypes are AO.We can set up a Punnett square to find the possible genotypes of their offspring:``` A O ----------------A | AA | AO | ----------------O | AO | OO |```From the Punnett square, we can see that there is only one combination out of four that results in type O blood (OO). Therefore, the probability of an offspring having type O blood is 1 out of 4, or 25%.So, the correct answer is .
