I recently adopted a pair of Cleartail Parrots and I have a question.

[815coke]

Hello, my name is Kim, and I live in south Korea.
Recently, I purchased a wonderful and lovely pair of clear-tail parrots. However, I have heard shocking news regarding this excellent pair of birds. Since both parent birds are clear-tail, it has been reported that the hatchlings may suffer from genetic defects, leading to poor eyesight and very poor health. I understand that in order to prevent genetic defects, at least one of the parent birds should be a clear-tail carrier (split). Is this true? Will all the offspring from this pair of birds I purchased be born with severe genetic disorders? That would be a very heartbreaking situation.
The birds I purchased are as follows: - Clear Tail Violet Blue/Cinnamon (Male) - Clear Tail Turquoise Blue Cinnamon (Female) They are not related by blood and are in a healthy condition.

How old are these two birds? Are they Indian Ringnecks?

Are you planning to breed them together? Can you breed them to different partners?
Sorry for this long message but I love bird genetics so here are my thoughts.
Assuming they're IRN cleartails (CT), it's a simple recessive gene. Your birds both have two CT genes.
I couldn't find any info online that indicates that breeding two visible, homozygous CT IRNs together causes priblem chicks.
The babies from this pair will be no different from any other CT IRN. The fact that both their parents are homozygous for CT only means that all their chicks will be CT.
Look at it this way- if both your birds were Heterozygous (split) for CT (visually normal) 25% of their chicks would be CT and those chicks would be no different from any other chicks that received those two CT genes, like if the parents were vislible CT homozygous. A CT chick from two CT parents is no different from a CT chick from a CT parent and a parent split for CT. Does this make sense?

I know that recessive pied budgies are bred together very frequently because the trait is attractive and their babies are not unhealthy. A recessive pied budgie from two recessive pied parents is no different from one with split parents- the genes are the same. They aren't different just because the parents each have two of them.

Some breeders of exhibition show English Budgies believe that breeding visual recessive pieds together results in offspring that lack the size breeders want but that's not a health issue.

Opaline is a sexlinked recessive in budgies (male needs two genes to show opaline and females need one) and male and female opalines are bred together all the time with quality chicks.

Lutino/ Albino (ino) is also sexlinked recessive but there is some evidence that breeding ino males with ino females produces weak young. Not sure why that would be since an ino from that pairing is not different from an ino from any other pairing. Perhaps ino birds are just weaker anyway and combining two weaker birds is a bad idea. If the ino gene makes birds weaker somehow, it would seem that the weakest ino birds would be the males because they have a double dose of the weak ino gene. Ino affects much more than color pattern. The melanin pigment is gone and the eyes are red. The gene could cause changes that we cannot see that weaken the bird. This would explain why ino male budgies are so rare- rarer than they should be just based on being sex linked. Opaline males need two recessive opaline genes and they are quite common and healthy.

Sorry if this was confusing or TMI. Genetics are weird.

두 마리를 함께 할 계획이신가요? 서로 다른 파트너와 싸울 수 있나요?
긴 글이 구성원입니다. 저는 새의 유전학을 좋아하기 때문에 제 생각에 최선을 다하고 있습니다.
IRN 해테일(CT)이라고 가정하면, 실제로 열성적인 경우입니다. 두 가지 새 모두 CT 문의를 두 번 가지고 계십니다.
두 눈에 보이는 동형 CT IRN을 함께 교배 문제가 있는 실체가 있으면 정보를 온라인에서 찾을 수 없습니다.
이 순간에서 새끼들이 CT IRN과 싸우고 있을 것입니다. 두 부모 모두 CT 동형접합체라는 사실은 단지 그들의 새끼들이 모두 CT일 것이라는 것을 의미할 것입니다.
이렇게 생각해 보세요. 만약 두 쇠고기 모두 CT(시각적으로 정상)에 대해 이형접합체(분열)상태라면, 새끼의 25%는 CT일 기준, 이 새끼들은 두 CT를 두려워하여 다른 사람들과 싸우고 바뀐 것입니다. 마치 부모 닭이 육안으로 CT 동형접합 체인처럼 보입니다. 두 CT부모에게서 태어난 CT 부분은 CT부모와 CT를 위해 부모가 분리된 상태에서 생성된 CT 부모와 제외된 것은 아닙니다. 그런거요?

열성 얼룩무늬 이상한 꼬리는 그 신기한 매력이 새끼가 건강하기 때문에 매우 자주 교배된다는 것을 알고 있습니다. 두 열성 얼룩무늬 부모에게서 태어난 열성 얼룩무늬 플로식은 부모가 물에 젖은 꼬리와 불편하지 않습니다. 기분이 나빠지기 때문이죠. 부모가 각각 두 번씩 자신을 가지고 있다는 것은 아닙니다.

일부 전시용 영국 사냥용 사냥자들은 열성인종 잡자가 사냥을 표시하고 교배하면 사냥을 원하는 크기에 작은 아이들이 없다고 믿기만 하면 건강 문제가 아니라고 합니다.

오팔린은 모임의 그룹 열성 권고입니다(수컷은 오팔린을 표시하기 위해 두 번의 권고가 필요하고 한 번씩 필요함). 원시과의 오팔린은 항상 새끼를 보호하기 위해 함께합니다.

루티노/알비노(이노)도 성연관 열성이지만, 이노 슬라이서과 이노는 교배하면 원시가 태어났다는 증거가 있습니다. 왜 그런지, 그 짝짓기에서 떠오르는 이노는 다른 짝짓기에서 일어나 이노와 싸울 수 없습니다. 어차피 이노라면 어차피 약할 수 있고, 두 마리의 한국을 합치는 것은 좋지 않다고 생각할 수도 없습니다. 만약 이노가 새를 약하게 말한다면, 가장 유능한 이노 새는 학원일 것입니다. 선택 이노를 두 배로 플레이하는 전투입니다. 이노는 색상 패턴보다 훨씬 더 많은 영향을 받습니다. 멜라닌 장치가 분리되고 눈이 붉은어옵니다. 이 변호사는 우리가 볼 수 없는 입장을 취할 수 있습니다. 이것이 이노 논쟁적인 꼬리가 왜 그렇습니까? 설명할 수 있습니다. 성연관성이라는 이유는 불가능합니다. 오팔린 학교는 매우 두 가지 열성 오팔린 불안이 필요하며, 자주 발생하고 건강합니다.

유일하게 구별되는 부분이 있다는 설명이 있었습니다. 괴학은 참

Thank you for your detailed answer. Korea is almost a wasteland when it comes to Indian Ringnecks. So your answer is very valuable. May I ask you one more question? Is Violet a recessive gene or a dominant gene? The person who sold me the bird told me Violet is a dominant gene, but others who have seen my bird say Violet is a recessive gene. Whose word should I trust?

 

[DonnaBudgie]

It's actually called "incompletely dominant". A bird with one violet gene will be visually violet, but unlike other dominant genes such as green (normal), a bird with two violet genes looks "more violet" than one with one violet gene.
