Study the given pedigree chart in which neither of the parents shows the trait but the trait is present in both male and female children.
Give one example of such a trait in human beings.
Show Hint
In autosomal recessive inheritance, both parents must be carriers of the recessive allele for the trait to be expressed in the offspring. Affected individuals inherit one recessive allele from each parent.
One example of an autosomal recessive trait in human beings is cystic fibrosis. This genetic disorder is caused by a recessive allele, and it can be passed on to children even if neither parent exhibits the trait, as both parents may be carriers.
