Gizmo Simulation: Human Karyotyping questions and answers 2023 Why do you think humans have two sets of 23 chromosomes? Humans have two sets of 23 chromosomes because you get a set from your mother and the other set from your father, resulting in two sets. What aspects of the genome can and cannot be determined through karyotyping? 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? female How do you think sex is determined in a person with a chromosomal disorder involving the sex chromosomes? 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? 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. Which type of chromosomal disorders seems to have the greatest affect on a person's health—disorders involving autosomes or sex chromosomes? Disorders involving autosomes have the greatest effect on health. Poor muscle tone; slanting eyes with folds of skin at the inner corners; short and broad hands and feet; small head; respiratory problems; speech problems; visual problems; hearing loss; heart defects and gastrointestinal problems possible; slow intellectual development.
