Vedclass · Answer

(B) Lyon's hypothesis states that the number of Barr bodies in a cell is equal to $(n - 1)$,where $n$ is the number of $X$ chromosomes.Down's syndrome is a chromosomal disorder caused by trisomy of chromosome $21$.The total number of chromosomes in a female with Down's syndrome is $47$,with the sex chromosome complement being $XX$.Using the formula: $	ext{Number of Barr bodies} = (	ext{Number of } X 	ext{ chromosomes} - 1) = (2 - 1) = 1$.Therefore,a human female suffering from Down's syndrome has $1$ Barr body.

Based on Lyon's hypothesis,what will be the number of Barr bodies found in a human female suffering from Down's syndrome?
