INBREEDING

Matings involving parents and siblings.

E.g. of inbreeding Brother/Sister (closest most dangerous) Father/Daughter (useful for testing foundation and F1 genetic soundness or setting specific traits) Mother/Son (useful for testing foundation and F1 genetic soundness or setting specific traits) Half-Brother/Half-Sister (most useful and considered line-breeding depending on the non-shared parents)

LINEBREEDING

Matings involving relatives other than parents and siblings. Cousins (have one or two Grandparents in common) Nephew/Aunt (most rationale line breeding) Niece/Uncle (most rationale line breeding) G. Granddaughter/G. Grandson Grandchild/Grandparent

NOTE: shared relatives past the 4th generation has little effect except in rare instances

BACKCROSSING

Breeding an outcrossed animal back into one of its original lines.

This assumes the outcrossed animal was derived from two specific germ-lines

OUTCROSSING

The breeding of unrelated animals. Only considered outcrossing if both are inbred or linebred and from separate lines.

SCATTERBREEDING

Do not share any common ancestors in the first 4 generations.

(Matings involve unrelated animals.)
