Inbreeding depression on cognitive abilities.

<p>The regression analysis presents almost similar trend for VIQ, PIQ and FSIQ. The slope depicts fitness decline (regression slope) with increase of inbreeding coefficient (F). The observed linear decline in fitness for cognitive parameters; (A) VIQ (R² = 0.436), (B) PIQ (R² = 0.468) and (C) FSIQ (R² = 0.464) are found to be significant. Pearson correlation ‘r’ for VIQ, PIQ and FSIQ are −0.660, −0.684 and −0.681 respectively, and found to be statistically significant (p<0.01). The negative values indicate the decreasing trend for cognitive abilities due to inbreeding.
