Biology - Inheritance of autosomal recessive characteristics

Inheritance of autosomal recessive characteristics

The recessive characteristic will only be apparent in the individual if he
or she is homozygous [1] for the allele of that trait. For example,

* An affected individual can have two unaffected parents (both will be
heterozygous [2] for that trait) [3]

* If the two parents show the characteristic (both must be homozygous)
then all the children will also show the characteristic

* Males and females are equally likely to show the characteristic (not
X-linked).

Examples of genetic disorders [4] following the autosomal recessive [5]
pattern of inheritance include:

* Phenylketoneuria

* absence of growth hormone

* cystic fibrosis

* albinism.
