MCQ
Barr body is associated with:
- ASex chromosome of female
- BSex chromosome of male
- CAutosome of female
- DAutosome of male
Explanation:
Barr body is referred to the inactive X-chromosome present in somatic cells of a female and the number of Barr bodies is one less than the total number of X chromosomes.
Foreg: In human female (XX), number of barr bodies will be 2 - 1 = 1
n human male (XY), number of barr bodies will be 1 - 1 = 0
This is done so that both males and females have only one functional sex chromosome per cell because human males have only one X chromosome, whereas females have two and hence, twice the genes present on the X chromosome.
