Scientists to be able to identify chromosomes under the microscope as early on as ns 19th century. But what did that take for them to ilustración out how important chromosomes yes, really are?
los second fifty percent of ns nineteenth siglo was a tiempo of remarkable advances in hereditary research. As at an early stage as the 1860s, Gregor Mendel and Charles Darwin began to explore feasible mechanisms the heredity. Then, gastos generales the próximo few decades, Walther Flemming, Theodor Boveri, and Walter Sutton make a series of significant discoveries including chromosomes, including what these frameworks looked like, exactly how they moved throughout mitosis, and what function they likely played in ns transmission of hereditary characteristics. However, it wasn\"t until the work of tabla de cortar Hunt Morgan in the early twentieth century that researcher were lastly able to straight link the inheritance of hereditary traits to los behavior of chromosomes, thereby offering concrete proof for what became known as ns chromosome theory of heredity.
los year 1865 was significant by two profound biological breakthroughs: Mendel\"s publishing of his experiment in tree hybridization, and Darwin\"s provisional theory of pangenesis. Back neither male had any kind of direct evidence for ns theories that proposed, Mendel speculated the cells included some type of coeficiente that brought traits from one generation to ns next, if Darwin proposed the traits can be passed down via devices he termed \"gemmules,\" i m sorry he thought traveled representar every body part to the sexual organs, where they to be stored (Benson, 2001). Due to the fact that these very first attempts to explain the mechanisms of heredity lacked any scientific support, their profound importance went unrecognized by ns scientific comunidad for decades. Nonetheless, Mendel y Darwin\"s occupational laid ns foundation for formulating a testable, research-based concept of heredity.

Meanwhile, several independent advances-namely, exploration of chromosomes y their behavior during mitosis as explained by , y discovery of ns link between chromosomes and heredity as explained by Theodor Boveri-began to shed brillante on the events the take place in ns nucleus during cell division y their implications. Then, some thirty-five año later, the significance the Mendel\"s work was emphasized by Walter Sutton, whose observations of chromosome behavior during cabinet division and gamete formation were consistent with Mendel\"s findings. Thus, the basis because that chromosome theory, y the zona of cytogenetics, was created.
