백합 상과의 계통분류학적 유연관계를 알아보기 위하여 14 종의 이치 아강 이매패류와 3 종의 익형 아강 패류를 대상으로 28S rRNA의 일부 염기서열을 분석한 뒤 GenBank에 등록된 관련 종들의 염기서열을 취득하여 PAUP 프로그램을 이용하여 최대 절약분석을 실시한 결과 다음과 같은 결과을 얻었다.분석된 1,480 개의 형질 (gap 포함) 중 560 개의 형질이 parsimony 결과 informative하였다. 하나의 가장 절약적인 분지도를 구했을 경우 전체 분지의 길이는 2765였고 consistency index (CI) = 0.4843, homoplasy index (HI) = 0.5157, Retention index (RI) = 0.6291 로 나타났다.동일 종 표본, Corbicula fluminea와 Sinonovacula constricta의 경우 각각 3.1 %, 1.2%의 차이를 보였다.Pitarinae-Cyclininae-Meretrinae가 하나의 분지를 이루고 있었고, Samaranginae-Chioninae-Dorsininae가 다른 하나의 분지를 이루고 있었다.
To elucidate the phylogenetic relation of the superfamily Veneroidea, we obtained partial 28S rRNA sequences of 14 heterodonts and three pteriomorphs which were collected from Korea and the sequence data of related taxa from GenBank, and analyzed maximum parsimony with PAUP program.750 of the nucleotide positions were variable, 560 of which were informative under conditions of parsimony. Total tree length was 2,765, and consistency index, homoplasy index (HI), and Retention index was 0.4843, 0.5157, and 0.6291, respectively. Intraspecific variation of 28 rRNA of Corbicula fluminea and Sinonovacula constricta was 3.1% and 1.3%, respectively. Pitarinae-Cyclininae-Meretrinae group had a clade and Samaranginae, Chioninae, and Dorsininae were clustered.
