D URING THE FIRST DECADE of the twentieth century it was established that the sex of almost all many-celled biological organisms is determined at the moment of fertilization by the combination of two kinds of microscopic entities, the X and Y chromosomes.1 This discovery was the culmination of more than two thousand years of speculation and experiment on how an animal, plant, or human becomes male or female; at the same time it provided an important confirmation for the recently revived… Expand

Women as Mendelians and Geneticists
After the rediscovery of Mendel’s laws of heredity in 1900, the biologists who began studying heredity, variation, and evolution using the new Mendelian methodology—performing controlled hybridExpand

TLDR
This paper will illustrate how the older metabolic theory of sex was displaced when those who argued for the relatively newer theories of chromosomes and hormones gradually formed an alliance that accommodated each other and excluded the metabolic Theory of sex. Expand
Theodor and Marcella Boveri: chromosomes and cytoplasm in heredity and development
TLDR
The contributions of Theodor B overi and his co-worker, Marcella O'Grady Boveri, to the understanding of heredity and development go beyond the localization of the Mendelian hereditary factors onto the chromosomes. Expand
