Question

if a father is ia ia and a mother is ia ib, what is the probability for a child with ab blood type? 0% 25% 75% 50%

Explanation:

Step1: Determine parental alleles

Father's genotype: \( I^A I^A \), so he can only pass \( I^A \).
Mother's genotype: \( I^A I^B \), so she can pass \( I^A \) or \( I^B \), each with 50% chance.

Step2: Create Punnett square

	\( I^A \) (Father)	\( I^A \) (Father)
\( I^B \) (Mother)	\( I^A I^B \)	\( I^A I^B \)

Step3: Calculate probability of AB

From the square, 2 out of 4 (or 50%) of the offspring have \( I^A I^B \) (AB blood type).

Answer:

50% (corresponding to the option with "50%")
