A Correlation of Cytological and Genetical Crossing-Over in Zea Mays

Open access
Creighton, Harriet B., McClintock, Barbara·1931·Proceedings of the National Academy of Sciences

Abstract

In this paper, McClintock and Creighton conclusively demonstrated the occurrence of genetic and cytological crossingover, a process assumed but not proven since 1910. In it they took two genetic markers and two cytological markers and demonstrated that when crossing-over occurred, they traveled together.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
