This experiment was carried out to identify the differences of genetic materials as genetic marker for the three chick breed.
The characteristics of chick chromosome were as follows. The 10 pairs chromosomes generally identified by morphology vary in size from about 7 ㎛ to small dot. It was identified that chromosome #1 and 2 were grouped as sub-metacentric, #3 was telocentric, #4 was as acrocentric and #5 was as metacentric and sex chromosome Z. Residual as intermediate chromosomes is found as acrocentric for #6, #7, #8, #10 and sub-metacentric for #9. Metacentric sex chromosome W was similiar size of the #9.
The identification of the egg type, meat type, and dual purpose type chicken was also as follows. Egg type chick was featured by the less band at distal part of #1-p and #4-q than others. Dark band adjacent to centromere of meat type chick was found as the specific marker and in dual purpose chick was more bands at #1-p, #2-p, and central part of #3 than the other breeds.
