Final answer:
A karyotype is a true representation of chromosomes arranged in pairs, depicting the number and appearance of chromosomes, including size, banding pattern, and centromere position.
Step-by-step explanation:
The statement is true: a karyotype indeed represents a photograph of an individual's chromosomes grouped in pairs, in order. A karyotype details the number and appearance of chromosomes, which include their length, banding pattern, and centromere position. A karyogram or ideogram is the actual photographic image that is obtained when a cytologist arranges the photographed chromosomes into pairs to analyze them for any genetic abnormalities such as monosomy or trisomy, which are conditions characterized by the loss or gain of a chromosome, respectively.
