If a gene is monomorphic, it means that all individuals in the population have the same allele for that gene. Therefore, a cross between any two individuals in the population would always result in offspring with the same genotype and phenotype for that gene, with a phenotypic ratio of 1:0 or 1:1, depending on whether the gene is dominant or recessive.
