Sex-linked Inheritance in Drosophila cover

Sex-linked Inheritance in Drosophila

The text presents experimental analyses of inheritance in Drosophila, beginning with Mendelian segregation and extending to linkage, crossing-over, and chromosomal behavior including Y chromosome effects and non-disjunction. It catalogues numerous mutations and multiple allelomorph systems, discusses sex-linked lethal factors, sex-ratio effects, environmental influences on expression, sexual polymorphism, fertility and inviability, and practical nomenclature. The core is a detailed genetic map of the X chromosome constructed from extensive cross data, recombination percentages, and methods for correcting double crossovers and coincidence. Individual sections present linkage results and breeding data for many specific loci and propose standardized symbols for mutant and wild-type alleles.

About the Author

Morgan, Thomas Hunt portrait

Thomas Hunt Morgan

Thomas Hunt Morgan was an influential American geneticist known for his pioneering work in the field of genetics and evolution. He is best recognized for his research on the fruit fly Drosophila melanogaster, which laid the groundwork for modern genetics. Morgan's notable works include "A Critique of the Theory of Evolution" and "Sex-linked Inheritance in Drosophila," where he explored the mechanisms of heredity and the implications of genetic variation. His contributions significantly advanced the understanding of genetic inheritance and adaptation, earning him the Nobel Prize in Physiology or Medicine in 1933. Morgan's legacy continues to impact the fields of genetics and evolutionary biology.
