As for the mothers v fathers question, it's a little harder to paint, for several reasons:
1. Sometimes disitnctions are drawn between filicide and infanticide (which is almost exclusively committed by mothers) making a wholistic view impossible.
2. No distinctions being made between small dependent children and teenage or grown children. It's relatively common for fathers and their grown sons to fight, and one of them ends up dead.
3. No distinctions between fathers and stepfathers (or cuckolds).
No one study seems to put them all together, and I can't be buggered reconciling them all. However:
Quote:Gender differences in filicide offense characteristics--a comprehensive register-based study of child murder in two European countries.
OBJECTIVE:
This study searched for gender differences in filicidal offense characteristics and associated variables.
METHODS:
In this bi-national register-based study all filicide perpetrators (75 mothers and 45 fathers) and their crimes in Austria and Finland 1995-2005 were examined for putative gender differences. The assessed variables were associated with the offense characteristics, the offenders' socioeconomic and criminal history, and related stressful events.
http://www.ncbi.nlm.nih.gov/pubmed/21620158ALL cases in these 2 countries for a decade returned 75 instances attributable to the mother to 45 attributable to the father.
AND:
Quote:59 percent of filicides were committed by mothers, 39 percent by fathers

Abstract
Quote:Background Filicide is the murder of a child by a parent. Historically, filicide was regarded as a female crime, but nowadays, in the West, men have become increasingly likely to be convicted of killing their child. Previous research on filicide has primarily focussed on either maternal or paternal filicide rather than comparing the two.
Aim The aim of our study is to examine and compare the socio-demographic, environmental and psychopathological factors underlying maternal and paternal filicide.
Methods Data were extracted from records in a forensic psychiatric observation hospital in Utrecht, in the Netherlands for the period 1953–2004.
Results Seventy-nine men and 82 women were detained in the hospital under criminal charges in that period, having killed (132) or attempted to kill (29) their own child(ren). Differences between men and women were found with regard to age, methods of killing and motivation underlying the filicide.

To me this is the most interesting part:
Quote:Historically, filicide was regarded as a female crime, but nowadays, in the West, men have become increasingly likely to be convicted of killing their child
The modern west...where the increasing number of men killing "their" child runs parallel to increasing numbers of men living with children that aren't theirs.
