$XXY$

Vedclass · Answer

(B) The number of Barr bodies in a cell is calculated using the formula $N = n - 1$,where $N$ is the number of Barr bodies and $n$ is the total number of $X$ chromosomes.Given that the male has one Barr body $(N = 1)$,we can substitute this into the formula: $1 = n - 1$,which gives $n = 2$.This means the individual has two $X$ chromosomes.Since the individual is male,the presence of a $Y$ chromosome is mandatory.Therefore,the genetic constitution is $XXY$,which is characteristic of Klinefelter syndrome.

If the somatic cells of a male contain one Barr body,what would be their genetic constitution?
