- Abstract
The article focuses on the use of chromo-helicase DNA (CHD) binding gene which is successful to sex almost all bird species with the notable exception of the kiwi ratites. Through the sequences analyses of the Z and W chromosomes, it shows that they are almost identical in length. The primer have been used to sex over 30 kiwi and is a useful tool for New Zealand's captive breeding program in North Island Brown Kiwi Apteryx australis mantelli. The DNA with altered electrophoretic mobility is known to be curved and common in DNA sequences from the W chromosomes of chickens.
