Charlie has a normal karyotype. He has:

A. One X chromosome
B. One Y chromosome
C. 23 chromosome pairs
D. 46 chromosomes
E. Two X chromosomes
F. Two Y chromosomes

Answer :

Answer: Charlie is XY, 46chromosome, 23 pairs

Explanation: Charlie has a normal male karyotype 46XY

48XXYY is an abnormal syndrome associated with tall stature but intellectual disability, developmental delays and other problems

Charlie, with a normal karyotype, has 23 chromosome pairs including one X and one Y chromosome, totaling 46 chromosomes. The normal karyotype does not include a combination of two X chromosomes and two Y chromosomes.

Charlie has a normal karyotype. The correct answers to the question are as follows:

  • A. He has one X chromosome and one Y chromosome -- this is characteristic of a normal male karyotype.
  • B. 23 chromosome pairs -- this is the total number of chromosome pairs in a normal human karyotype.
  • C. 46 chromosomes -- this is the total number of chromosomes in a normal human karyotype.

The incorrect answer is:

  • D. Two X chromosomes and two Y chromosomes -- this configuration does not represent a normal human karyotype as it contains too many sex chromosomes.

A normal human karyotype consists of 22 pairs of autosomes and 1 pair of sex chromosomes. For males, the sex chromosomes are one X and one Y (XY), while for females, they are two X chromosomes (XX).
