Give me the ansure for the bold letter capital B and ansure for (d)

Offspring number 1 is a male, represented by a square. The square is not shaded, indicating he is a normal male.

His mother is represented by a circle with a diagonal line, indicating she is a normal carrier female ($X^H X^h$).
His father is represented by an unshaded square, indicating he is a normal male ($X^H Y$).

Since offspring 1 is a normal male, he must have inherited the $Y$ chromosome from his father and a normal $X^H$ chromosome from his mother.
Therefore, his genotype is $X^H Y$.

The genotype of offspring number 1 is $\boxed{X^H Y}$.
