Question

anonymous · Answer

no becoz attached means reccessive and if it is attached it means dominant gene of unattached ear lobe is absent in both

preetha · Answer

No they cannot have kids with free, unattached earlobes.  Attached earlobes are recessive, which means both parents are homozygous for the recessive gene. (ff).  IF Free earlobes are represented as FF (F=dominant Free earlobe), the parents are ff.  The offspring can only have ff. Draw the Punnet square to see how this works out.  100% of the offspring will have attached.
