GENETICS OF DERMAL RIDGES: PARENT‐CHILD CORRELATIONS FOR TOTAL FINGER RIDGE‐COUNT

SummaryParent‐child correlations have been estimated for total ridge‐count using new data from 100 families with 104 sons and 91 daughters.Parent‐child, mother‐child and father‐child correlations are not significantly different from 0·5. The interparental correlation is 0·02 ± 0·10.The new data have been combined with the earlier data from 49 families. The parent‐child correlation estimated from this total sample is 0·50, the mother‐child correlation 0·49 ± 0·04 and the father‐child 0·50 ± 0·04. Mother‐son, mother‐daughter, father‐son and father‐daughter correlations are not significantly different from 0·5.
