Estimating timing of admixture

Question

[Matteo]

Hi everyone,

I would like to know if there is a way to estimate the number of generations since the admixture event given a hybrid individual in an admixed population. I am aware of an approach used in vonHoldt et al., 2022 (https://www.science.org/doi/10.1126/sciadv.abn7731), but they use total genome length in cM, which is not available at the moment in my system. Is anyone aware of other approaches?

Thank you in advance!!

Matteo
