摘要

Objective

The purpose of this dataset is to document familial patterns of some observable human phenotypes within an Indian population. The data are collected to support the study of inheritance mechanisms across both well-established Mendelian traits and phenotypes with uncertain or population-dependent inheritance, and to provide a pedigree-based resource for methodological and computational research.

Data description

The dataset comprises phenotypic information from 250 parent–offspring triplets. Five observable traits are recorded: ABO blood group, Rhesus (Rh) factor, widow’s peak, facial dimples, and facial freckles. Data are collected using a structured questionnaire administered to adult participants, who reported their own traits as well as those of their biological parents. Minimal preprocessing was applied, and no statistical imputation was performed; missing values are explicitly encoded. Data validation was conducted by comparing observed inheritance patterns and phenotype frequencies for ABO blood groups and the Rh factor against expected population values to assess biological plausibility and population representativeness. The dataset is suitable for studies of genetic inheritance, evaluation of computational inheritance models, and development or benchmarking of intelligent imputation techniques.
