How this entity was disambiguated
This entity first appeared as the object of triple T5644305 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.
Target entity: Sturtevant’s Law Context triple: [Edgar H. Sturtevant, notableWork, Sturtevant’s Law]
-
A.
Mendel's laws
Mendel's laws are the foundational principles of heredity that explain how traits are inherited through discrete genetic units from one generation to the next.
-
B.
Haldane’s rule
Haldane’s rule is a principle in evolutionary biology stating that when in the offspring of two different animal species or subspecies one sex is absent, rare, or sterile, that sex is usually the heterogametic one (e.g., XY or ZW).
-
C.
Hardy–Weinberg principle
The Hardy–Weinberg principle is a fundamental concept in population genetics that describes how allele and genotype frequencies remain constant from generation to generation in an idealized, non-evolving population.
-
D.
Alfred Sturtevant
Alfred Sturtevant was an American geneticist best known for creating the first genetic linkage map of chromosomes, laying foundational work for modern genetics.
-
E.
law of segregation
The law of segregation is a fundamental principle of genetics stating that the two alleles for a trait separate during gamete formation, so each gamete carries only one allele for each gene.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
