Answer:

Explanation:

If the disorder is recessive, neither parent has to have the disorder because

they can be heterozygous. The characteristic features of autosomal recessive inheritance is as follows:-

•Appears in both sexes with equal frequency

• Trait tend to skip generations

• Affected offspring are usually born to unaffected parents

• When both parents are heterozygous approx. 1/4 of the progeny will be affected

• Appears more frequently among the children of consanguineous marriages.

The given pedigree follows these features. So the correct option is 'Autosomal recessive trait'.

Please correct me If I am wrong :)
