## Question

How do thegenealogymeasurements sharestructure withoutsharingweights?

## Inputs

## Results

```json
{
  "measurement_insertion": {
    "path": "model/operations_measure_and_insert.json",
    "sha256": "cfbb6e920db5eb788f74fb7c86f2dd626159d63a619c7cd7f93085bc6184951c",

  }
}
```

## Finding

Orderedmeasurement produces completefields fromselectedweights. Insertion changes thestructurebefore measurement, soCainan’sdifferentRegular andCumulative contributions remainlinkedtoone source row.
