Tests for Identifying Carriers Because most children with recessive disorders are born to parents with a normal phenotype, the key to assessing  risk is identifying whether prospective parents are heterozygous carriers of the recessive trait. Recently developed tests for many disorders can distinguish normal phenotypes in heterozygotes from  homozygous dominants. o These results allow individuals with a family history of a genetic disorder to make informed decisions about  having children. o Issues of confidentiality, discrimination, and counseling may arise. Fetal Testing Tests are available to determine  in utero  whether a child has a particular disorder. One technique,  amniocentesis,  can be used from the 14th to 16th week of pregnancy to assess whether the fetus  has a specific disease. o
