Whole genome duplication events have occurred frequently during the course of vertebrate evolution. To better understand the influence of polyploidization on the fish genome. we herein used the autotetraploid Carassius auratus (4n = 200. RRRR) (4nRR) resulting from the whole genome duplication of Carassius auratus (2n = 100. https://missouriquiltcoes.shop/product-category/dress-making-scissors/
