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
