What we see in the image is a genealogy, where a disease or trait is highlighted. Each square and circle represents an individual, and its color represents whether they have the disease (completely black), are carriers (half and half), or are healthy (white).
In this case, both squares and circles can be carriers, so this is not a disease carried in the sex chromosomes, and this also means two copies are needed for the disease to express, so the individual with the disease (black) are homozygous recessive. This means that individual 5 from generation II is NOT homozygous recessive.
Usually, squares represent males and circles represent females, so that means that II-5 would be a female heterozygous.
