A dominant trait is passed on to all offspring wether it is a dominant from a trait like pastel as opposed to het pastel or granite.
whereas with spiders and also pinstripes there is no "super" and they do not prouduce all spiders or pinstripes so cannot be dominant
albinos are recessive meaning that the trait only shows in the homozygous form ie. the hets look like normals
as i said before adominant trait is passed onto all offspring
hope this helps
