Question

Pedigree analysis on a characteristic shows:

a)the characteristic affects M and F equally
b)2 unaffected parents can have an affected child
c)in fam which parents are unaffected but children are affected, 1/4 affected

Answer 1

Pedigree analysis is used to study the inheritance of traits over generations and predict the probability of offspring inheriting a genetic disorder. The characteristic in this analysis is inherited in an autosomal recessive manner.

Step-by-step explanation:

A pedigree analysis is used to study the inheritance of traits over several generations in a family. It can help determine the probability that offspring will inherit a genetic disorder. Based on the information provided, we can infer that the characteristic being studied in this pedigree analysis is inherited in an autosomal recessive manner.

This means that:

1. The characteristic affects males and females equally.
2. Two unaffected parents can have an affected child.
3. In families where both parents are unaffected but children are affected, there is a 1/4 chance of having an affected child.
