Drosophila melanogaster와 D. simulans 및 그들간 잡종의 형태학적 유연관계
Morphological Relationship between Drosophila melanogaster, D. simulans and their Hybrids
초록
Drosophila melanogaster(OR)와 D. simulans(09) 및 그들 종간 잡종 사이의 형태적 유연관계를 비교하기 위하여 내.외부생식기 및 성즐을 조사하였다. 이를 위하여 D. melanogaster 암컷과 D. simulans 수컷의 교배에서 암컷을, 그 정역 교배로서 수컷을 얻었으며 두 종간 사이의 잡종
The morphological relationship between Drosophila melanogaster and D. simulans, and their hybrids were investigated using comparisons of internal reproductive organs. male sex comb tooth number and male genital discs. InterspecIfic hybrids of all crosses were completely sterile, and had rudImentary gonads. Dysgenic ovaries and testes were morphologically similar to those of gonadal dysgenesis stenlity associated with the PM system in D. melal1ogaster. The mean number of sex comb tooth in D. melrmogaster, D. simulans and their male hybrids were 10.73, 8.35 and 9.97, respectively. The general aspects of the genital disc of the malo hybrid were a mosaic-like structure between D. melanogaster and D. simulans.
