Female sex chromosome

Vedclass · Answer

(A) The $Barr$ body is a condensed,inactive $X$ chromosome found in the nuclei of somatic cells of female mammals.It is formed due to the process of $X$-inactivation (lyonization),where one of the two $X$ chromosomes in females is randomly inactivated to ensure dosage compensation.Since males have only one $X$ chromosome $(XY)$,they do not typically possess a $Barr$ body.Therefore,the $Barr$ body is specifically associated with the female sex chromosome complement.
