Answer
The first type of macromolecule present in the karyotype is protein. Proteins play a crucial role in the structure and function of chromosomes, including histones, which help package DNA.

Answer
The second type of macromolecule in the karyotype is nucleic acid, specifically DNA. DNA is the genetic material contained within the chromosomes.

Answer
To determine if the individual’s karyotype differs from a normal human karyotype, one must analyze the number of chromosomes and their structure. A typical human karyotype contains 46 chromosomes (23 pairs). If the individual has more or fewer chromosomes, or any structural abnormalities in the chromosomes (such as deletions, duplications, or translocations), then the karyotype would be considered different from the normal range.
