Answer 1

To match each person with the correct allele combination based on the information provided:

• Father’s Mother (Bb) - brown hair
• Mother’s Father (BB) - brown hair
• Mother (Bb) - brown hair
• Child (bb) - blond hair

Assuming that:

• "B" represents the dominant allele for brown hair.
• "b" represents the recessive allele for blond hair.

Here are the pairs of individuals with their possible allele combinations:

1. Mother’s Father: BB (as given)
2. Father: Bb (inferred based on the child's phenotype and parental combinations)
3. Father’s Father: BB (inferred since Father’s Father must provide a dominant allele for brown hair)

So the matches would be:

• Mother’s Father: BB (brown hair)
• Father: Bb (brown hair)
• Father’s Father: BB (brown hair)

The answers in the format as you provided:

• Mother’s Father: BB
• Father: Bb
• Father’s Father: BB
