To fill in the missing allele combinations for each individual based on the given information, we can look at the inheritance patterns for brown (B) and blonde (b) hair.

  1. Father’s Mother (brown hair): She has the genotype Bb (heterozygous), which is indicated.

  2. Father’s Father (brown hair): Since the father has brown hair and his mother is Bb, he must also be either BB or Bb. However, since a blonde child (bb) was produced, the father must also carry the blonde allele. Thus, Father’s Father must be Bb.

  3. Mother’s Mother (brown hair): The genotype is given as BB (homozygous dominant).

  4. Mother’s Father (blonde hair): This individual must be bb (homozygous recessive), which aligns with him having blonde hair.

  5. Father (brown hair): The father must be Bb because he has a blonde child (bb), indicating he carries a recessive allele.

  6. Mother (brown hair): As indicated, her genotype is Bb (heterozygous).

So, matching each person with the correct allele combination:

  • Father’s Mother: Bb
  • Father’s Father: Bb (inferred)
  • Mother’s Mother: BB
  • Mother’s Father: bb
  • Father: Bb
  • Mother: Bb

In summary, the matches are:

  • Mother’s Father: bb
  • Father: Bb
  • Father’s Father: Bb
