Abstract
The chromosome number and karyotype of amphioxus Branchiostoma belcheri tsingtauense were studied using embryonic cells. The diploid chromosome number (2n) of B. belcheri tsingtauense is 36, and its karyotype 2n=36, 2st+34t, FN=36. This is the first report on the karyotype of the cephalochordate. Evidence suggesting the possible presence of a pair of sex-chromosomes in the amphioxus has been provided.
