A female sex cell has six Barr bodies. How many X chromosomes are there in this cell?
Answer= 7 x-chromosomes
Explanation:
Number of Barr bodies= no. Of X-chromosomes - 1
6= n - 1
n = 6+1
n= 7

True or False: Sex chromosomes in mammals Indicate whether each of the following statements about sex chromosomes in mammals is true or false. 01. Dosage compensation involves inactivation of the Y chromosome in males in order to equalize gene expression between the sexes.(Click to select) 02. One of the X chromosomes in each cell of a female is inactivated early in embryonic development, before the embryo's sex is determined. (Click to select) 03. In a female, the same X chromosome...
