Which of the following is true of a human karyotype?
A. Each cell has 22 pairs of homologous chromosomes.
B. Each cell has one pair of sex chromosomes.
C. The chromosomes are numbered in order from 1 to 22.
D. All of the above are true.
Answer (2)
The answer i am sure is B as there are 23 pairs of chromosomes (which eliminates all others)
In a human karyotype, each somatic cell contains 23 pairs of chromosomes, including 22 pairs of autosomes and 1 pair of sex chromosomes. The correct statement is option B, which says each cell has one pair of sex chromosomes. Options A and C contain inaccuracies, making all of the options not true at once.
