My dad is 100% Irish and my mom is 100% English. Does that make me half of each?

Question:NO! One parent's "blood" does not rule. First, it is not the blood they pass down. It is the DNA that is passed down. In order to create you, 2 "seeds" had to come together (the egg and the sperm). Each have the same number of DNA. Then when the 2 come together (conception), the fetus then has all the DNA from BOTH "seeds". Therefore, exactly 50% of your DNA is from mom and 50% from your dad. As far as what DNA "rules", that is another issue. Your traits (hair color, eye color, etc.) can be dominant or recessive. The trait that is dominant will be what you look like (brown eyes are dominant over blue), but if you have the gene for the recessive trait as well, you could pass that on to your kids.

If your dad is 100% Irish and your mom is 100% English, then you are 50% Irish and 50% English. However, as far as which one you look like it dependant on what combination of dominant vs. recessive traits you got from them. Looking more like one parent than the other does not make you more that parent (75% of dad and 25% of mom, etc.). You are STILL 50-50 of each parent.

you would be considered a pappose baby

id have 2 guess 50-50

That makes you 200% what ever YOU want to be!
Are you going to start saying Begorrah or Bejabers and dancing jigs?
Are you going to start eating Fish & Chips and Yorkshire Pudding while reciting Shakespeare?
No!
The whole thing is meaningless, although others who are obsessed by the Heritage concept would say you are half English, or half Irish. But if you go back a few generations you will probably find that both of your parents were part something else in their ancestry!

it entitles you to dual nationality anyway

Makes you100 % you

It depends upon the culture you are in.
In the 1800's, ancestry ruled. If you were born of seemingly white parents, you could still be considered black if you had just 1/16 of the blood of a slave in your ancestry.
My husband, of mostly German- American descent, was born with a 32nd of Apache blood, yet he could have been considered a minority and given special rates for his schooling.
In the mainstream culture, you are 1/2 English and 1/2 Irish.

NO. That makes you 50% Irish and 50% English.

your dads blood rules

Its entirely up to you, what ever avenue you go down is the one you want to follow.

Your nationality is where you were born and the country of which you are a citizen. Your ethnic origin apparently is 50-50 English and Irish.

Blood has nothing to do with relationship. That is old hat. It is genes that relates you to your family, not blood. Autosomal DNA you get 50-50 from both parents and it is the only DNA that relates a female to her father.

Y DNA is passed solely from father to son.

Mitochondrial DNA is passed from mother to both son and daughter but only the daughter passes it on to her children.

Your DNA can be taken by a swab on the inside of your cheek. using blood is irrelevant.

your 50% irish 50% english

50% 50% is my vote

There are three intrinsic questions here - blood, ethnicity and citizenship.

Citizenship - unless extraordinary measures were taken, this is typically the country in which you were born

Ethnicity - this is the predominant culture in which you grow up. If that's in England, then your culture is English/British - dependent on the extent of your exposure and travel. If that's in Ireland, then your culture is Irish/perhaps British, depending on where you live in Ireland, and the extent of your exposure and travel.

Blood - this does not change, because it is biological. If your parentage is truly 1 x 100% English, and 1 x 100% Irish, then that makes your BLOOD 50% of each.

Reality - 10 generations ago you had over 1000 grandparents. 20 generations ago you had over 1Million grandparents. Yes, that's right. If they're all Irish on one side, and all English on the other - great. If they're not - great. It just pays to know that most of what we research involves patriarchal names first, and that's really a very small percentage of who we are. Enjoy!
