dense_meiosis#

pybrops.core.util.mate.dense_meiosis(geno, sel, xoprob, rng)[source]#

Perform meiosis on matrix inputs. Assumes diploidy.

Parameters:

geno (numpy.ndarray) –
A phased genome matrix of shape (nphase,ntaxa,nvrnt).

Where:
- nphase is the number of chromosome phases.
- ntaxa is the number of taxa.
- nvrnt is the number of variants (markers).
sel (numpy.ndarray) –
A selection configuration array of shape (nsel,) containing indices of individuals for which to perform meiosis.

Where:
- nsel is the number of individuals for which to perform meiosis.
xoprob (numpy.ndarray) – A crossover probability array of shape (nvrnt,) containing sequential probabilities of recombination.
rng (numpy.random.Generator, numpy.random.RandomState) – A random number generator instance.

Returns:

gamete – A gamete matrix of shape (nsel,nvrnt).

Return type:

numpy.ndarray
