If the father were to be tested, he probably would show at least 70%
"European Jew." However, it's a throw of the dice as to which 50% of a
given parent's DNA is inherited. So, for example, the mother is
reportedly 45% Irish; the daughter, 22%. However, Iberian Peninsula are
12% and 11%, respectively. That does not necessarily mean the father is
almost 20% Iberian.
You should take ethnicity estimates >from DNA with a grain of salt.
Though the results derive >from statistical analysis, some of the
underlying assumptions are based heritage reported by those who were
tested in addition to their DNA structure. There is no "Ashkenazi
Jewish" gene, for example.
