미토콘드리아는 모계유전
예 그래서 ㄱ이 아버지인건 알겠는데 ㄷ이 어머니인거는 어떻게 알죠?
1번 염색체는 상염색체이므로 전기영동 결과가 자녀가 부모의 일부를 받은 형태가 되어야 하고, 미토콘드리아는 모계유전이므로, 자녀의 전기영동 결과는 어머니의 결과를 따라가게 되서 같은 결과가 3명이 나오게 되죠
그림 (나)에서 같은 결과가 3명이 아니므로 (나)는 1번 염색체이고, ㄱㄷ의 일부가 ㄴㄹ에서 표현되므로 ㄱㄷ가 부모, ㄴㄹ가 자녀입니다.
(가)를 보면 ㄴ과 ㄷ의 결과가 같으므로, ㄹ의 결과도 이와 같아야 하고, ㄱ 과 ㄷ중에서 ㄷ이 어머니, ㄱ이 아버지가 됩니다.
답변 감사합니다!ㅎㅎ그럼 자녀의 전기 영동 결과는 부모의 서열과 겹치는 것들로만 구성되어 있어야 하는건 가요?
아 이해됐어요! 감사합니다^^
그냥 하나하나씩 해보세요 ㄴ이 어머니라고 가정했을때 아들,딸이 유전자형태가 나올수있는지 하는식으로요
구체적으로 말씀해 주실 수 있나요? 가정을 해도 그 다음에 어떻게 판단해야 하는지 모르겠어서요ㅠㅠ
서열이 나와 있는 것도 아니고 길이로만 판단하는거라 어떻게 해야 할지 감이 안 잡히네요ㅠㅠ
