Answer:
All their descendants will be heterozygous for the skin color, Bb, expressing blue skin.

<u>Available data</u>:
- Smurfette has light blue skin
- Her family is a "true bred" or "purebred" line.
- She married a boy who has light yellow skin
- blue skin is the dominant trait expressed by the B allele
- yellow skin is a recessive trait, expressed by the b allele
Cross: Smurfette x Husband
Parentals) BB x bb

F1) 100% of the progeny will be heterozygous for the skin color, Bb
100% of the progeny will be blue-skinned.
Note: Although the progeny is blue-skinned, they are not true-bred anymore.
