Line bred traits and dominant traits are not really related...



Dominate traits would still be controlled by a single allele, and are very similar to recessive traits. The kicker is that while a recessive trait has to have two copies of the recessive to express the trait, a dominant trait only has to have one copy.



A line bred trait is controlled by multiple alleles, that is why there is such great variation in line bred offspring.



Here is a breakdown:



XX = wildtype

Xx (recessive trait) = het, does not show the trait

Xx (dominant trait) = het, shows the trait

xx (recessive trait) = shows trait

xx (dominant trait) = shows trait, can even be fatal in some instances



I'm sure Jeff can add to this.
