Final answer:

In a male individual, there would be zero Barr bodies, as they only have one X chromosome. A typical male with one X chromosome would not have any Barr bodies, as Barr bodies are condensed X chromosomes that occur in human females to account for the double genetic dose.

Step-by-step explanation:

In a female, one of the X chromosomes is randomly inactivated during embryonic development to compensate for the double genetic dose. This inactivated X chromosome forms a dense structure called a Barr body. Since males only have one X chromosome, they do not have Barr bodies. Therefore, the number of Barr bodies in the cells of a male individual would be zero.

A typical male with one X chromosome would not have any Barr bodies, as Barr bodies are condensed X chromosomes that occur in human females to account for the double genetic dose. Gametes have half the chromosome number of somatic cells, so from a muscle cell with 32 chromosomes, the resulting gamete would have 16 chromosomes after meiosis.

How many Barr bodies would you predict in his cells? Since Barr bodies are the inactivated X chromosomes found in cells, and they occur in human females, a typical male with one X chromosome would not have any Barr bodies. Barr bodies are formed during X inactivation, a process that compensates for the double genetic dose in females by condensing one of their two X chromosomes into a Barr body.

If a muscle cell of a typical organism has 32 chromosomes, then the gamete of that organism would have 16 chromosomes. This halving of the chromosome number occurs through meiosis, a special type of cell division. In humans, which typically have 23 pairs of chromosomes in somatic cells, the gametes - sperm or egg - contain 23 single chromosomes.
