We then compared the frequencies of human cancer genes among total genes inthe Z-homologous regions of HSA 5 and 9 (9.3%) and theautosome-homologous regions of HSA 5 and 9 (10.0%), which are notsignificantly different by a chi-squared test on frequencies (Table 4).Then we compared the frequencies of cancer genes on the chicken Z (13.7%) withthe frequencies of the autosomal regions on the rest of HSA 5 and HSA 9(13.9%), which is also nonsignificant. Here, ALB is linked to cancer.
