F1 hybrid

                                       

From Wikipedia, the free encyclopedia

                                                                                               
Jump to: navigation, search
                                               

F1 hybrids are the first filial generation seeds/plants or animal offspring resulting from a cross mating of distinctly different parental types, the offspring of which produce a new, uniform variety with specific and/or desirable characteristics from either or both parents. In fish breeding, those parents frequently are two closely related fish species, while in plant and animal genetics those parents usually are two inbred lines. Mules are F1 hybrids between horse and donkey. Crossing specific parent plants produces a hybrid seed (plant) by means of controlled pollination. To produce consistent F1 hybrids, the original cross must be repeated each season. As in the original cross, in plants this is usually done through controlled hand-pollination, and explains why F1-seeds are so expensive.

In agronomy, the term “F1 hybrid” is usually reserved for agricultural cultivars derived from two different parent cultivars, each of which are inbred for a number of generations to the extent that they are almost homozygous. The divergence between the parent lines promotes improved growth and yield characteristics through the phenomenon of heterosis, whilst the homozygosity of the parent lines ensures a phenotypically uniform F1 generation.

Gregor Mendel's groundbreaking work in the 19th century focused on patterns of inheritance and the genetic basis for variation. In his cross-pollination experiments involving two true-breeding, or homozygous, parents, Mendel found that the resulting F1 generation were heterozygous and all phenotypically resembled the dominant parent plant. Mendel’s discoveries involving the F1 and F2 generation lay the foundation for modern genetics. Today, classification of certain domestic hybrid breeds, such as the Savannah (cat), are classified by their filial generation number.

That's funny - I had this fantasy that you were on the same island
If you did then I thought that it would be a situation that might call for bending breeding rules - those ethical ones.

Anthony,

 

Case in point!

 

My Taurus was not a great specimen. I never bred him, even though his dam produced the National Specialty Winner ....Gulf Mills Resounder!

 

These choices are totally personal, but should be based on good objective judgement!

 

You can never second guess yourself after the fact!

My favorite "Mom" besides June Cleaver was Ch. Lionsire Indigo of Pax River (Indy)

Bred to my favorite fella Ch. Ironhill's Warwagon..(Dave)

 

They happened to produce lines of BIS, BISS, on and on..

She was a true "brood bitch" in every sense of the word. BUT, she was not the prettiest, tallest or "finished before 2" gal on the block.

Her and Dave not only produced great kids, grandkids, great..but check out the hip testings..mostly OFA goods, to OFA Excellents.

 

I'm NOT a breeder (I think we have established that), but I do know "good breeding" when I see it..it is also behind the generations, not just the parents..research, research..

 

Some of the nicest bitches in recent years (Ivana) have come from these lines also..I like to see a generation or two or three to decide what this kennel name or that has contributed to our breed..just because someone happens to have a male or female anything does not a breeding make.

 

I'm also partial to St. Patricks and Ivory's lines..you can see type AND height with proper balance..
