x-chromosome inactivation was investigated cytologically using the modified kanda method which differentially stains inactive x-chromosome material at metaphase in balanced 13 1/2-day female embryos heterozygous for four x-autosome rearrangements , reciprocal translocations t ( x ; 4 ) 37h , t ( x ; 11 ) 38h and t ( x ; 16 ) 16h ( searle 's translocation ) and the insertion translocation is ( 7 ; x ) 1 ct ( cattanach 's translocation ) .
