Question

1. cross a father, who has type \o\ blood with a mother, who has type \b\ (homozygous) blood. what is the probability that they will have a child with type \o\ blood?

Explanation:

Step1: Determine Genotypes

Blood type O is recessive, so father's genotype: \( ii \). Mother is homozygous B, so her genotype: \( I^B I^B \).

Step2: Gamete Production

Father produces only \( i \) gametes. Mother produces only \( I^B \) gametes.

Step3: Punnett Square Cross

	\( I^B \)	\( I^B \)
\( i \)	\( I^B i \)	\( I^B i \)

All offspring have genotype \( I^B i \), which is blood type B. So no offspring have type O.

Answer:

The probability is \( 0 \) (or \( 0\% \)).
