The phrase “father and daughter close relative patched” suggests a possible scenario where a “patch” refers to a software fix, a genetic data correction, or a relationship database update.

| Component | Possible Meaning | |-----------|------------------| | | High Density — often refers to SNP chips (e.g., Illumina’s HD array with >500,000 markers) | | NACR221 | Likely a sample ID, batch code, or lab identifier (e.g., “NA” = North American, “CR” = close relative) | | father and daughter | First-degree biological relatives sharing ~50% autosomal DNA | | close relative | In genetic terms: parent-child, full siblings, or grandparent-grandchild | | patched | Corrected in software — either a falsenegative/false positive match or a relationship misclassification |

For genetic genealogists, forensic analysts, and bioinformaticians, understanding such patches is essential. It reminds us that even the closest biological relationships can be obscured by data errors — and that meticulous “patching” ensures truth prevails in our genetic records.
