ML

O

OOA

Out of Africa Theory, posits a single, recent origin of modern Homo sapiens out of Africa, following Homo erectus and Homo Neanderthalensis.

P

p p-value

the probability of obtaining a result, given a true null hypothesis/zero correlation.

R

r

In stats, the correlation coefficient ranging from -1 to 1, where 0 means no linear correlation.

r^2

"R squared": In stats, the coefficient of determination, i.e. the proportion of variance in the dependent variable that can be explained by the independent variable. "How well the data fits the model"

Race

A categorization of humans based on phenotype or ancestry, often corroborated with genetic clustering.

S

Sex

SNP

Single Nucleotide Polymorphism, the occurrence of a swapped nucleotide at a single point of the genome, in at least 1% of the population

SNV

Single Nucleotide Variant, the occurrence of a swapped nucleotide at a single point of the genome, in < 1% of the population
