Genotype is what is there, though this would be in terms of genes not whole chromosomes. And phenotype is what is expressed. Also the eye color example is a good one though don't forget that this is determined by more than just two alleles of one gene, so it's a little simplistic but still a useful example. Genotype not being the same as Phenotype can get a little sticky once you get into codominance or genetic masking. More simply put, take the example of a heterozygote. The subject would have a dominant allele and a recessive one for a gene.
The myelodysplastic syndromes (also known as MDS or myelodysplasia) are hematological (i.e., blood-related) medical conditions with ineffective production (or  dysplasia ) of all blood cells. Patients with MDS can develop severe anemia and require blood transfusions. In some cases, the disease worsens and the patient develops cytopenias (low blood counts) caused by progressive bone marrow failure. The outlook in MDS depends on the type and severity. Many people live normal lifespans with MDS. The myelodysplastic syndromes are all disorders of the hematopoietic stem cells in the bone marrow (only related to myeloid lineage). In MDS, hematopoiesis (i.e., blood production) is disorderly and ineffective. The number and quality of blood-forming cells decline irreversibly, further impairing blood production. The mean age of onset of MDS is 68 years.
Myelodysplastic Syndrome. Myelodysplastic syndrome (MDS) is group of disorders typified by peripheral cytopenia, dysplastic hematopoietic progenitors, a hypercellular bone marrow, and a high risk of conversion to acute myelogenous leukemia (AML).
