Het= Heterozygous, one dominant allele and one recessive allele. The dominant masks the recessive.

If you can visibly see the albino or blizzard trait, that means that they are Homozygous. (either two dominant alleles or two recessive alleles)

If you want to breed albino leo geckos or blizzard leopard geckos, then your best chances would be breeding the leo to another leo with the same morph.
