Through the comparison of autosomal DNA tests between several family members, specific segments of DNA can often be assigned to common ancestors. Though chromosome mapping has typically focused on segments shared in common, segments not shared in common can also be useful. Although chromosome mapping can be very helpful, there are some situations where caution should be used in applying these techniques - particularly for small segments, endogamous populations, and pile-up regions. In this hands-on lab, participants will use a public dataset and third-party chromosome mapping tools to create a chromosome map. They will be guided through all steps of downloading segment data, preparing a csv file, and running the mapping tool. Participants will learn about considerations for hierarchical versus collateral relationships and will create maps for both. Though participants are welcome to use their own datasets, we strongly encourage use of the public dataset while participants are learning.
This computer lab is also taught on Thursday at 4:30 p.m.
