Accepted Answer

Compensatory mechanisms may arise, leading to a viable but abnormal phenotype.

Answer

The phenotype can be accurately predicted without additional information.

Answer

Loss of both genes will not result in any developmental defects.

Answer

Loss of both genes will lead to a normal developmental phenotype.
