A parent-offspring phenotype dataset from an Indian population

Area of Science:

• Human genetics
• Population genetics
• Phenotypic inheritance

Background:

• Understanding human inheritance patterns is crucial for genetic research.
• Familial aggregation of traits provides insights into genetic and environmental influences.
• Indian populations offer unique genetic diversity for studying inheritance.

Purpose of the Study:

• To document familial patterns of observable human phenotypes in an Indian population.
• To support the study of inheritance mechanisms for Mendelian and complex traits.
• To provide a pedigree-based resource for methodological and computational research.

Main Methods:

• Phenotypic data collected from 250 parent-offspring triplets.
• Recorded traits include ABO blood group, Rhesus factor, widow's peak, facial dimples, and freckles.
• Data gathered via structured questionnaires with minimal preprocessing and no imputation.

Main Results:

• The dataset captures familial inheritance patterns for five common human phenotypes.
• Validation confirmed biological plausibility and population representativeness of ABO and Rh factor data.
• The dataset is suitable for evaluating computational inheritance models and imputation techniques.

Conclusions:

• This dataset provides a valuable resource for studying human genetic inheritance in an Indian context.
• It facilitates research into both simple Mendelian traits and complex phenotypes.
• The data supports the development and testing of advanced computational genetics methods.
