Case study: A black-haired mother and a black-haired father have triplets, with 2 having black hair and 1 having ginger hair. Why does that 1 child have ginger hair instead of black hair? The child with ginger hair was swapped during birth. The mother has an affair with a ginger-haired man. The father had an affair with a ginger-haired woman. The ginger-haired child has a condition that causes a change in his/her hair color. The ginger-haired child inherited 2 recessive alleles. The ginger-haired child inherited a dominant allele.

The ginger-haired child inherited 2 recessive alleles.

In the case study above, what could be the possible genotype of the mother? Black hair Ginger hair BB Bb bb None of the above

In the case study above, what could be the possible genotype of the father BB Bb bb Black hair Ginger hair None of the above

In the case study above, what could be the possible genotype of the ginger-haired child? BB bb Bb None of the above Black hair Ginger hair
