GIZMOS 2026 ACTUAL EXAM QUESTIONS
WITH SOLUTIONS GRADED A+
◉What aspects of the genome can and cannot be determined
through karyotyping? Answer: Karyotyping can give information on
an individual's sex and on chromosomal disorders. Karyotyping does
not give any information on the specific traits encoded in an
individual's genes.
◉What sex would a person with trisomy X be? Answer: female
◉How do you think sex is determined in a person with a
chromosomal disorder involving the sex chromosomes? Answer: Sex
is determined by the presence or absence of a Y chromosome. Males
have Y chromosomes while females do not.
◉Why do you think this might be the case? Answer: Syndromes
involving sex chromosomes have symptoms related to the
development of sex characteristics, rather than the functions of
major body systems. Thus, most of the genes located on sex
chromosomes probably only code for reproductive system traits.
The genes on other chromosomes code for essential life functions.
Therefore, autosomal disorders would involve genes that are
necessary to a person's survival. Because of this, autosomal
disorders would be more deadly.
