Question

are there any traits that are found in a parent, but seem to \disappear\ in all their children?
□ dimples
□ no dimples
□ cleft chin
□ no cleft chin
□ a widows peak
□ no widows peak
□ attached earlobe
□ detached earlobe

Explanation:

Traits are determined by genes. Recessive traits can be masked in offspring if the other parent contributes a dominant - allele. For example, if a parent has a recessive trait like attached earlobes (recessive to detached earlobes), and the other parent has detached earlobes with a dominant allele, the recessive attached - earlobe trait can seem to disappear in the children.

Answer:

Attached Earlobe
