Kung pag babasihan kasi ang book ni legates and warwick (animal breeding) pag sinabi mo na F1 ito yun anak ng 2 superior na animal at ang f2 naman ay anak nung F1 na nabreed sa F1 din na usually kapatid niya.

Although yun iba pinasimple ito basta anak ng f1 = f2, anak ng f2 = f3..... or F1 x F1 = F2,
F2 x F2 =f3

so hindi necessary na dpat GP lang ang makakaproduce ng F1 ... Ang F1, F2, F3 is more of designation lang so kung ibabase natin sa tao, parang anak, apo, apo sa tuhod.... yan ang sequence nila.

sa dami din ng interpretation medyo iba iba din ang makukuha mo na sagot....

Hi Doc Nemo,
Ako naman ay iba ang pagka intiende ko.
Example :
           LR X LW = F1
       
           F1 X LW = F2
           F1 X LR  = F2

           F1 X Duroc or DurocPietren = market hogs
           F2 x Duroc or DurocPietren = market hogs

LW x LR = F1  kung mapapansin mo sa definition ni legates and warwick anak ng 2 superior animal, so pasok siya dun sa definition.


LRxLW (magulang) = F1 (anak) x LW = F2(apo) , kung ibabase naman natin sa simple definition ko na magulang, anak , apo (disregarded kung ano breed niya, pwede din kasi na LRxLR = F1)

F1 x duroc or duror pietrain = market hogs or F2 x duroc / duroc pietrain = market hogs.....

sa case na ito ang market hogs kasi is not necessary na duroc ang kapartner or pietrain....
as long as and end mo is pang benta, market hog siya ke LW, LR, D, Pietrain ang mix.

itong later part kasi  ng 2000's nauso yun idea sa pilipinas na ang market hog dapat pietrain and duroc ang partner, pero hindi ito necessary.


kaya din medyo magulo ang definition ng sa animal breeding, nagstart kasi ang genetics sa plant na usually nagcrocross pollinate , kaya ang binilang is yun number ng pollination within the same  group ng plant and yun succeding generation nila.

How about Purelines matatawag bang GP ito?

Merun kc akong Purebreed Landrace sired by Pure Landrace, F1 ba anak nya or GP pa din kc Purelines
Base kc dun sa post ni babuylaber "F1 is a crossbreed of 2 GP"

nabasa ko naman po somewhere na
GGP -lolo/lola
GP -nanay/tatay
F1 -anak
F1xGp -upgraded F1
F2 -F1xF1

nakakalito rin minsan kaya kung di rin lang tayo magkakaroon ng universal book na susundin, mabuti pa ngang dun na tayo sa sinabi ni doc na "designation" no matter what the breed as long as kita mo performance at sure ka namang hindi nahahaluan ng pangmarket na lahi pwede natin itong idesignate sa ating kagustuhan.

I agree with Doc Nemo at sau Babuylover. As long as we meet the forecasted target date and liveweight of market hogs natin at alam mo ang genetics ng alaga mo.

Doc nemo..

Ang Pietrain x Duroc boar F1 po dba. Normally po ba PietrainDuroc (PTD) ang tawag doon??
Kasi merong iba DurocPietrain (DPT) ang tawag nila doon..

Ano po pagkakaiba sa dalawang tawag na ganon??
Salamat.

nasusunod po kung sino yun barako yun ang mauunang name...

Pietrainduroc = pietrain ang tatay and nanay is duroc.

or  kung minsan kung sino yun mas mataas ang blood line siya ang mauuna...
PetrainDuroc x Duroc = DPT
