A study of the erythrocyte carbonic anhydrases of 219 American ponies and 76 riding horses has revealed the presence of five variants of the low-activity CA B isozyme and two variants of the high-activity CA C isozyme. The previously undetected variant of CA C was found only in the pony population and had an allele frequency of 8.9%. A family study of animals possessing the CA B variant A2 showed an unexpected high frequency of inheritance.
一项针对219匹美国矮种马和76匹骑乘马的红细胞碳酸酐酶研究发现，存在低活性CA B同工酶的五种变体和高活性CA C同工酶的两种变体。此前未检测到的CA C变体仅在矮种马群体中发现，其等位基因频率为8.9%。对拥有CA B变体A2的动物进行的家系研究显示出意外的高遗传频率。
