There are nineteen cases of both parents having the commonest of the loop
patterns, No. 42, on a corresponding finger. They have between them
seventy-five children, of whom forty-eight have the pattern No. 42, on the
same finger as their parents, and eighteen others have loops of other
kinds on that same finger, making a total of sixty-six coincidences out of
the possible 75, or 88 per cent, which is a great increase upon the normal
proportion of loops of the No. 42 pattern in the fore, middle, and
ring-fingers collectively. Again, there are three cases of both parents
having a tendrilled-loop No. 15, which ranks as a whorl. Out of their
total number of seventeen children, eleven have whorls and only six have
loops.
Lastly, there is a single case of both parents having an arch, and all
their three children have arches; whereas in the total of 109 children in
the table, there are only four other cases of an arch.
This partial analysis accounts for the whole of the like-patterned
parents, except four couples, which are one of No. 34, two of No. 40, and
one of No. 46. These concur in telling the same general tale, recollecting
that No. 46 might almost be reckoned as a transitional case between a loop
and a whorl.
The decided tendency to hereditary transmission cannot be gainsaid in the
face of these results, but the number of cases is too few to justify
quantitative conclusions. It is not for the present worth while to extend
them, for the reason already mentioned, namely, an ignorance of the
allowance that ought to be made for related patterns. On this account it
does not seem useful to print the results of a large amount of tabulation
bearing on the simple filial relationship between the child and either
parent separately, except so far as appears in the following paragraph.
_Relative Influence of the Father and the Mother._--Through one of those
statistical accidents which are equivalent to long runs of luck at a
gaming table, a concurrence in the figures brought out by Mr. Collins
suggested to him the existence of a decided preponderance of maternal
influence in the hereditary transmission of finger patterns. His further
inquiries have, however, cast some doubt on earlier and provisional
conclusions, and the following epitomises all of value that can as yet be
said in favour of the superiority of the maternal influence.
