Answer:
III-5 is male.
Individual III-5 is affected by the genetic condition.
Individual III-5 is the proband.
Explanation:
In human pedigrees, males are represented by squares while females are represented by circles. Individuals affected by the focus trait in human pedigrees are usually shaded, those that are carriers are half-shaded, while those that are not affected at all are not shaded in any form.
Thus, from the pedigree (see the attached image), III-5 individual is a male and affected by the genetic condition in focus.
Also, III-5 individual is a proband, because a proband is an individual that is first affected by a genetic trait in a family.
