Recent common ancestry of human Y chromosomes: evidence from DNA sequence data.
TLDR
It is estimated that the spread of Y chromosomes out of Africa is much more recent than previously was thought, and the data indicate substantial population growth in the effective number of human Y chromosomes. Expand

TLDR
This paper introduces a method for finding the ages of mutations, given the total number of mutations on the tree, and the result is useful in examining the underlying assumption of a relatively constant population over time. Expand
Estimation of Inbreeding from Population Samples
Some simple methods of estimating inbreeding from tests on a random sample of individuals are discussed. These are mostly iterative procedures, converging to the maximum likelihood estimate, withExpand
CURVES AND ALIGN: SOME NEW COMPUTERIZED METHODS FOR THE ANALYSIS OF TREE -RING DATA
TLDR
These procedures are valuable as supplements to, not replacements for, the essential steps of crossdating and removing age effects as contained in the earlier INDXA program (Campbell 1973; Fritts 1975), and the subsequent revision as INDEX (Graybill 1979), developed by the Laboratory of Tree -Ring Research at the University of Arizona.

TLDR
A counting method to estimate the probabilities of origin of trisomy and triploidy and a method for finding the standard errors of the estimators is developed. Expand
