Answer:

Two recessive genes for attached earlobes

Explanation:

For a recessive trait to be displayed, it must mean that the individual does not possess a dominant allele that would be expressed instead of the recessive allele. Therefore, Ashley must have two copies of the recessive genes to have attached earlobes. Possessing one or two dominant genes for free earlobes would mean that she would have free earlobes.

This can also be visualised with a punnet square, see attached image. We know the parents carry a recessive allele but have free earlobes, so they must have the genotype Ff. The punnet square shows 3 genotypes are possible

FF, which would give free ear lobes

Ff, the same genotype as her parents, free earlobes

and ff, which would give attached earlobes.
