I am about to submit my UKF application from South Africa.
My father is not on my birth certificate and are no longer in contact, so I did a DNA test with my half-sibling from my father's first marriage. The DNA test was a legal test by an accredited company listed on the gov.uk website. However, the test report says,
Based on testing results obtained from analyses of the DNA loci listed, the probability of half-siblingship is 68.6%. The likelihood that they share a common biological parent is 2 to 1. This probability of siblingship is calculated by comparing to an untested, unrelated, random individual of the general population (assumes prior probability equals 0.50).
"According to AABB standards, combined likelihood rations of 0.1 through 10 are considered inconclusive for the relationship. Based on [testing company]'s standard battery of tests for kinship tests for kinship cases, approximately 11% of true second degree relatives (half-sibship, avuncular, single grandparents) will generate combined likelihood indices within this range. Testing of additional relatives is recommended.
So basically, it's saying we're probably related, but they can't confirm that we are half-siblings (spoiler alert - we definitely are, even our MyHeritage DNA profiles match up as half sisters). I am seriously annoyed, as before testing I had repeatedly asked the company in different ways if their test would confirm that my sister and I share the same father, and are agnate siblings. They had assured me it would. I have contacted my customer service advisor, and she has asked someone from the lab to call me back.
In addition to the report I will also be including:
- my father's full UK birth certificate (he was born in the UK to British parents)
- my full birth certificate with no details entered under father
- my half-sister's full UK birth certificate with our father's details
- my half-sister's UK marriage certificate showing her change of surname
- copy of my half-sister's British passport
- 2x photographs of me with my father and half-sister
- 8x photographs of me with my father over a period of approximately 10 years, including photographs of him giving me away at my wedding
I have no photos of my parents together and none of myself with my father as a child (long story).
Do you think these are sufficient? Do you think I should add anything else?
