Recessive gene

The trait of a dichotomous pair that is not expressed in the phenotype of heterozygous individuals [3]. The weaker of a pair of alleles in heterozygous combination [2]. The recessive gene is the second gene that has no effect [1].

A recessive trait is the weak, unexpressed trait of a dichotomous pair of alleles (dominant-recessive) that has no effect in the phenotype of heterozygous individuals. An example would be a child who has the dominant or expressed trait for curly hair combined with the weak, unexpressed, recessive trait for straight hair and thus would be a child with curly hair [2]. However, if two recessive genes for a particular trait are inherited by a child, such as albinism, the child will be albino [2]. Recessive traits have a definite impact on child development such that children can inherit recessive characteristics ranging from red hair or a straight nose to serious conditions such as hemophilia, color blindness, or...
