Line Breeding Chart
The line-breeding chart to the left shows a common
method of crossing a paternal (buck) and maternal
(doe) line.  Blue represents the paternal line and red
represents the maternal line.

"A" (buck) and "B" (doe) are the two original
rabbits the breeder is starting with.

"A" and "B" are bred together, producing the litter
"C" (doe) and "D" (buck).  The litter has 1/2 of the
paternal and 1/2 of the maternal lines and is the "F1"
generation.

"C" is bred back to her sire "A" which produces the
doe "E".  "E" has 3/4 of the paternal and 1/4 of the
maternal line. "E" is an "F2" generation litter.

"D" is bred back to his dam "B" which produces the
buck "F".  "F" has 3/4 of the maternal line and 1/4 of
the paternal line.  "F" is an "F2" generation litter.

The doe "E" is bred back to the original sire "A"
producing the buck "G" who is 7/8 of the paternal
and 1/8 of the maternal line. "G" is an "F3"
generation litter.

The buck "F" is bred back to the original dam "B"
producing the doe "H" who is 7/8 of the maternal
and 1/8 of the paternal line. "G" is an "F3"
generation litter.
At this point in the breeding program, the 7/8 "F3" generations can be crossed to each.  The buck "G"
will be bred to the doe "H" producing the "F4" generation litter "I" which contains 1/2 of the paternal and
1/2 of the maternal line.

"J" is a new buck that will now be introduced by breeding to the doe "I" producing litter "K" which has
1/2 of the new paternal line, 1/4 of the original paternal line and 1/4 of the original maternal line.  Litter
"K" can now be bred to "G" and "H" beginning the process over again now using "G" and "H" to breed
subsequent offspring back to.

If a trio was used to start the original herd, two separate lines can be started with each original doe, and
the two lines crossed when reaching the "F3" generation.
