Battle of Iwo Jima Battle of Iwo Jima The Battle of Iwo Jima (19 February – 26 March 1945) was a major battle in which the United States Marine Corps landed on and eventually captured the island of Iwo Jima from the Imperial Japanese Army (IJA) during World War II. The American invasion, designated Operation Detachment, had the goal of capturing the entire island, including the three Japanese-controlled airfields (including the South Field and the Central Field), to provide a staging area for attacks on the Japanese main islands. This five-week battle comprised some of the fiercest and bloodiest fighting of the Pacific War
Japanese Americans mainland of Japan. Studies of the mitochondrial component of Japanese American genes of haplogroup M12 shows a direct correlation of Japanese haplotypes with Tibetans. Other haplotypes that early descents of Japanese people were thought to be carried into include C-M8, which is another Y-chromosome haplotype. Also going back to the Jōmon, that gene is displayed in high frequencies in people of Japanese descent. The estimated percentage of this type of gene in Japanese Americans is about 34.7%. The highest frequencies occur in Okinawans and Hokkaidos. Overall, the genetic makeup of Japanese Americans show very mixed origins of genes, all due
