摘要:
It appears that nature has experimented extensively with various modes of gene duplication in fish. We witness extreme diversity in the genome size as well as in the degree of gene duplication among fish. There are those that have increased their genome size exclusively by repeated tandem duplication of chromosomal segments. They show no proportional increase in the number of functional gene loci. In this group, the trend for progressive elimination of excessive genetic redundancy appears to have started in modern times.
