영어에서 HOMEOTIC 의 뜻은 무엇인가요?
자만증
Homeosis는 특정 발달에 중요한 유전자의 돌연변이 또는 잘못된 발현으로 인해 발생하는 한 장기의 변형입니다. 동물에서 발견 된 Hox 유전자의 돌연변이 또는 식물의 MADS-box 계열과 같은 다른 돌연변이에 의해 유발 될 수 있습니다. Homeosis는 곤충이 성공적이고 다양 해지는 데 도움이되는 특성입니다. 가성 영양 돌연변이는 발달 과정에서 분절 정체성을 변화시킴으로써 작용한다. 예를 들어, Ultrabithorax 유전자형은 metathoracic과 첫 번째 복부 세그먼트 mesothoracic 세그먼트가되는 표현형을 제공합니다. 잘 알려진 또 다른 사례는 Antennapedia입니다. 기능이 향상된 대립 유전자는 다리 대신 안테나가 발달하도록합니다. 식물학에서 롤프 새틀 러 (Rolf Sattler)는 일반적으로 받아 들여지는 완전한 만성 보균증 외에도 부분적 가성 국증에 중점을 두어 가성 폐쇄증의 개념을 수정했습니다. 외과 식물의 homeotic 돌연변이는 야생에서 희귀 한 것으로 생각됩니다 : 연간 식물 Clarkia에서 homeotic 돌연변이는 꽃잎이 단일 열성 유전자에 의해 지배되는 돌연변이를 통해 발생하는 장기와 같은 sepal의 두 번째 희석으로 대체되는 것으로 알려져 있습니다.

Exploring Genetic Mechanisms
As we have seen, we know much about how the segmentation genes initiate
homeotic gene expression in flies. The gap genes play a particularly important
role in controlling where the homeotic genes are expressed along the A-P axis.
