| In some cases, children with dominant single gene disorders are born to normal parents. |
| Typically, altered gene dosage caused by karyotypic abnormalities results in embryonic lethality or birth defects. |
| The presence in wheat kernels of a cathepsin B gene led the search for its barley counterpart. |
| Several forms of familial hypercholesterolemia are the result of genetic defects in the gene encoding the receptor for low-density lipoprotein. |
| This system means that people who have two copies of the 'D' gene will be right-handed. |
| The next chapter gives excellent coverage of biosafety issues such as allergens and gene flow with considerable literature references. |
