in a karyotype of a female, which of the following would indicate a normal karyotype?
one x chromosome and one y chromosome
three copies of chromosome 22
two x chromosomes
a total of 48 chromosomes

Explanation:

In humans, females have a normal karyotype with two X - chromosomes (XX). Males have one X and one Y chromosome (XY). Three copies of chromosome 22 is an abnormal condition (trisomy 22), and the normal number of chromosomes in human somatic cells is 46, not 48.

C. two X chromosomes
