This study provides new data on chromosomal characteristics and DNA barcoding of three endemic loaches of Iran: spiny southern loach Cobitis linea (Heckel, 1847), Persian stream loach Oxynoemacheilus persa (Heckel, 1848) and Tongiorgi stream loach Oxynoemacheilus tongiorgii (Nalbant & Bianco, 1998). The chromosomes of these fishes were investigated by examining metaphase chromosome spreads obta...

There are many ways to portray the linear organization of the elements of the chromosomes. There are many types of chromosome maps just as there are many ways to represent the geographic map. In general , the human genome can be represented in physical maps or in genetic maps. The photograph of the high-resolution banded kar-yotype and the idiogram derived therefrom is a basic physical map and ...

We report the cytogenetic analysis of 124 adult male germ cell tumors ascertained consecutively at the Memorial Sloan-Kettering Cancer Center between 1988 and 1990. Biopsies from testicular and extragonadal pri mary and metastatic lesions studied included all histolÃ3gica!subtypes of germ cell tumors and cases of malignant transformation. Nonrandom numerical and structural chromosomal abnormali...

D mutants of wheat chromosomes (Endo, Four deletion mutants of rye chromosome 6R were identified in 1995; Endo and Gill, 1996) have proven to be progeny of wheat (Triticum aestivum L.) lines of ph1bph1b genotype valuable tools for mapping molecular markers and morand monosomic for chromosome 6R. The rye chromosome carried a phological characters to physical segments of chromoresistance gene aga...
