Glaucoma is a leading cause of blindness. Studies have linked a common form of glaucoma to three genes and more than 20 genetic loci. Which best describes glaucoma?
a recessive trait that requires multiple recessive alleles to be expressed
a polygenic trait that is influenced by the number of alleles present
a codominant trait that is expressed more often when more dominant alleles are present
a dominant trait that depends on the presence of only one of many dominant alleles

glaucoma are inherited, either as common complex traits or as mendelian autosomal dominant or recessive traits (early onset).
