Question

two parents with different blood types as indicated in this punnett square have children. what is the percent chance that their children could have the same phenotype for blood type as either parent? 0% 25% 50% 100%

Explanation:

Step1: Determine genotypes from Punnett - square

The genotypes of the offspring from the Punnett - square are $I^A I^B$, $I^A i$, $I^B i$, and $ii$.

Step2: Identify parent phenotypes

Assume one parent has genotype $I^A i$ (blood type A) and the other has genotype $I^B i$ (blood type B).

Step3: Identify offspring phenotypes

$I^A I^B$ has blood type AB, $I^A i$ has blood type A, $I^B i$ has blood type B, and $ii$ has blood type O.

Step4: Calculate the probability

The probability of having blood type A (like one parent) is $\frac{1}{4}$ and the probability of having blood type B (like the other parent) is $\frac{1}{4}$. The total probability of having the same phenotype as either parent is $\frac{1}{4}+\frac{1}{4}=\frac{1}{2}=50\%$.

Answer:

50%
