Detailed Description And Nomenclature Of High Resolution G-Banded Horse Chromosomes And Cytogenetic Analysis Of Hereditary Multiple Exostosis In Horses, Alma Maciulis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A reliable technique for obtaining late prophase, prometaphase and greater numbers of metaphase chromosomes is presented. The increased number of mitoses and high resolution chromosomes were obtained using a modification of the typical three-day blood culture technique in which the cell cycle was temporarily blocked at the G₁-s border with methotrexate. A high resolution G-band idiogram is presented using a system similar to the standardization of human chromosomes. The use of this technique and system of nomenclature will facilitate routine analyses of horse chromosomes and provide a basis for the identification and recording of chromosome aberrations in this …
