Despite recent progress on estimating the heritability explained by genotyped SNPs (h(2)g), a large gap between h(2)g and estimates of total narrow-sense heritability (h(2)) remains. Explanations for this gap include rare variants or upward bias in family-based estimates of h(2) due to shared environment or epistasis. We estimate h(2) from unrelated individuals in admixed populations by first estimating the heritability explained by local ancestry (h(2)Ξ³). We show that h(2)Ξ³ = 2FSTCΞΈ(1 - ΞΈ)h(2), where FSTC measures frequency differences between populations at causal loci and ΞΈ is the genome-wide ancestry proportion. Our approach is not susceptible to biases caused by epistasis or shared environment. We applied this approach to the analysis of 13 phenotypes in 21,497 African-American individuals from 3 cohorts. For height and body mass index (BMI), we obtained h(2) estimates of 0.55 Β± 0.09 and 0.23 Β± 0.06, respectively, which are larger than estimates of h(2)g in these and other data but smaller than family-based estimates of h(2).
Relationships between genetic distance and phenotype for a trait with heritability = 80%. (a) The phenotypic covariance of pairs of individuals at different expected fractions of genome shared IBD is 0.8*%IBD. (b) Regression of genetic distance estimated from genetic variation against the product phenotypes normalized to have mean 0.0 and variance 1.0 has coefficient 0.79 (se = 0.014). (c) Regression of genetic distance estimated from local ancestry variation against normalized phenotypes has coefficient 0.033 (s.e. = 0.007) β2FSTCΞΈ(1βΞΈ)h2= 0.032, corresponding to h2 = 0.83 (s.e. = 0.18).
LLM interpretation
This is a scatter plot showing the relationship between chromosome length (Mb) on the x-axis and heritability from local ancestry per chromosome on the y-axis. Red data points, labeled by chromosome number, are plotted against a positive linear regression line. The data points show a general upward trend, though several chromosomes (e.g., 4, 16, 18) fall near zero regardless of length.
Estimated heritability of height for each chromosome in the CARe data set. The numbers adjacent to each point are the chromosomes. We plot the regression line of h2 per chromosome regressed on chromosome length. We find a strong correlation between chromosome length and height heritability (Pearson correlation = 0.513, weighted p-value = 0.0028).
LLM interpretation
This figure consists of three scatter plots (a, b, and c) with red linear regression lines. Each plot relates a measure of genetic distance or relationship on the x-axis to a phenotypic measure on the y-axis: (a) Genetic Distance (IBD) vs. Phenotypic Covariance, (b) Genetic Relationship (Genotypes) vs. Product of Normalized Phenotypes, and (c) Genetic Relationship (Local Ancestry) vs. Product of Normalized Phenotypes. Plots (a) and (b) show a strong positive linear correlation, while plot (c) shows a much weaker positive correlation.
