You prepare a human karyotype. Upon analysis, you find 22 pairs of chromosomes that are each of approximately equal length and also a single pair that has one chromosome longer than the other. What can you conclude from this information?
A) The organism that this cell came from is likely a female.
B) The organism that this cell came from is likely a male.
C) The organism that this cell came from has a genetic disease.
D) This cell is likely haploid.

Question

Quizplus · Accepted Answer

Humans have 23 pairs of chromosomes, with one pair being the sex chromosomes. Females have two X chromosomes, while males have one X and one Y chromosome. The presence of one chromosome longer than the other in the sex chromosome pair indicates that this cell came from a male organism. The length of the other pairs of chromosomes is not indicative of any particular genetic disease, and without further information about the cell type, we cannot conclude whether the cell is haploid or diploid.
