help with genetic Q

Postby mgbirds on Thu Mar 20, 2008 4:01 pm

can anyone tell me what color my baby PF lovebird is? i will email a pic. i don't know how to put on this site.

this bay is a very bright yellow(lutino yellow) but has a light blue rump. i also think it may be an orange face (not sure since i've not seen on esp. a baby) one other baby is a WF violet creamino (pretty sure) it looks just like the one in the ALBS library pics. not sure if this helps much, but can send pics

any help is app. or if you could direct me to where i should look.

thanks michelle

I'm thinking your breeder friends would have better chance of helping you than we would.

One possibility is that the baby is genetically a "pied" without any of the patches of green that you would expect, but one of the parents would have to be a "green series" bird.
You are correct that the creaminos are in the "blue series" and are a softer yellow, which would be the case in a violet creamino.

this is probly a dumb Q, but can a bird be green and blue series? can it be a visual green, but carrie the blue genes or vice versa?

Hey maybe your bird is one of these
http://africanlovebirdsociety.com/genet ... ewing.html
just browse on the sight and see if it helps. I hope it does. Your bird sounds really pretty.

Opps, I've seen that your already been on the sight. does it look like that? Are you sure it's a pf lovebird mutation?

Green birds can be split for blue. Green is dominant as the Sun is Dominant in the sky during the day, but when it's night, the stars shine. The blue mutation would be like the stars...

Green birds ARE blue, with yellow. To get green you must mix blue and yellow together. If you take away the yellow, you get a blue bird. If you take away the blue, you get a yellow bird. You can't take away the green, because green is TWO mutations. If you take away both yellow AND blue, you get a white bird.

The only way you can have a visual blue and green bird, is if it were a turquoise, which means that the yellow is not fully reduced/removed from the alleles, thus producing a blue-green bird. (well this may not be correct, but it gives you an idea)

Blue birds cannot be split green as they would not have the yellow needed to produce a green bird. However, if paired with a green bird, they will have green offspring, since the chicks will get the yellow coloration from one parent... unless of course that parent is split to blue, then you'll get blue and green offspring.

There is a "seagreen" mutation, which is actually a "blue" series color, but the body feathering looks like a clear green, not as muddy as the normal green, and not as pale as the cinnamons. The face is the pale grey of the blue series, with just the line of peach on the forehead. I saw one in a pet shop...almost 20 years ago. Wish I had bought it. I don't know how this would have affected the other color combinations.

thanks for all the help everyone! its so much fun trying to figure all this out. i've sold three babies and will prably keep the other two, at least til i decide if i will breed them. probly need to get them sexed. if i have a hen and a cock. i may keep them both and find them mates just to see what the two sexes might produce. esp. since the males can carry more genes than hens. never know maybe i'll keep them as pets. they are soooo cute!

thanks again

Hi,

I do not breed my birds but have a question. Are these two babies from the same parents? If they are - and are male and female, would you breed them? I thought that you shouldn't breed birds that are related and they could have health prblems? I am just curious and trying to learn about the different colors and mutations in love birds myself.

Some amount of inbreeding can be done (called linebreeding) so long as one ensures to bring in new blood every once in a while... and to not breed too closely together... i.e. brother and sister. The closest I've heard is adviced to breed is parent to offspring, since they only share half the amount of genes... but that it's also fine to breed in aunts, uncles, neices, etc.

I am by no means a breeder either, but I understand that if you allow birds too closely related to breed it WILL cause health problems, but at the same time it may take a few generations before anything becomes apparent.

In short though, inbreeding or linebreeding is usually done to try and bring out specific traits, such as maybe a specific color, or maybe size and shape.

Also, what I've heard about line breeding you need to be ready to keep only the best. Many that are line breeding don't talk about it because they do kull the ones that aren't "perfect" in their eyes. Not something that I would have the heart to do.

Inbreeding is breeding siblings together. Line breeding is mother to son then to grandson etc. It locks in the traits almost like cloning. You can run into trouble when each parent carries the same undesirable trait and it comes out. You double the chances of the good as well as the bad traits. And yes you do have to be ready to cull what is considered bad traits. It is basically how all the different breeds got established, like in the different dogs, cats etc. Also how letting the bad traits come through as to where the hip problems are with some breeds of dogs.
Line breeding after a while, all the offspring looks the same in every way. You can regconize where [who bred or raised] the animal came from by type color etc.
You only run into trouble when both parents carry the bad trait so they can pass it on to the siblings. Some traits are recessive and others are sex linked.

As far as I understood it, linebreeding and inbreeding were the same thing... (in a sense) Since inbreeding means breeding within the same family.... now I'm sure many will argue that inbreeding is breeding closely related animals, where-as linebreeding is breeding animals that are not as closely related (i.e. aunt and nephew at best, maybe).... With that idea some may argue that the two examples you've given are thus inbreeding. As far as I really see it, linebreeding is a form of inbreeding.

http://dictionary.reference.com/browse/inbreeding
in·breed·ing
Biology. the mating of closely related individuals, as cousins, sire-daughter, brother-sister, or self-fertilized plants, which tends to increase the number of individuals that are homozygous for a trait and therefore increases the appearance of recessive traits.

inbreeding
The breeding or mating of related individuals within an isolated or closed group of organisms or people. Inbreeding can result in inbreeding depression. However, in agriculture and animal husbandry, the continued breeding of closely related individuals can help to preserve desirable traits in a stock.


http://dictionary.reference.com/browse/linebreeding
line·breed·ing
Genetics. a form of inbreeding directed toward keeping the offspring closely related to a superior ancestor.

line·breed·ing
the interbreeding of individuals within a particular line of descent usually to perpetuate desirable characters

linebreeding
form of inbreeding ( in inbreeding )
The closest type of inbreeding is selfing, or self-fertilization, the union of male and female sex cells produced by the same organism. Linebreeding is a form of inbreeding that involves selection of mates on the basis of their relationships to a certain superior ancestor. The backcross (crossing a first-generation hybrid with one of the parental types) is a common method of inbreeding.


http://www.britannica.com/EBchecked/top ... inbreeding
inbreeding
the mating of individuals or organisms that are closely related through common ancestry, as opposed to outbreeding, which is the mating of unrelated organisms. Inbreeding is useful in the retention of desirable characteristics or the elimination of undesirable ones, but it often results in decreased vigour, size, and fertility of the offspring because of the combined effect of harmful genes that were recessive in both parents.
