| If a mother is heterozygous for a particular sex-linked gene, her son has a 50% chance of inheriting either allele from her. |
| We sequenced genomic DNA from heterozygous animals in an attempt to identify the remaining mutations. |
| This method magnifies the effect of heterozygous mutations on the posterior phenotypes, thus identifying even lethal genes involved in the targeted process. |
| In addition, researchers studied persons with diabetes, obesity, individuals heterozygous for phenylketonuria, and lactating women. |
| All families harbored compound heterozygous mutations, most commonly a truncating mutation combined with a missense mutation. |
| Animals developed as perfectly normal hermaphrodites if derived from a heterozygous hermaphrodite mother. |
