Bovine fetal and adult globin genes were cloned and subjected to DNA sequence analysis. Both of these genes contained insertions of Alu-type repetitive DNA within their introns. Comparison of cow and goat beta-type globin genes indicates that intragenic DNA insertions played a role in their evolution. These data support the theory that Alu-type repeats maintain genetic diversity by inhibiting gene conversion.
