  • Machine learning on alignment features for parent-of-origin classification of simulated hybrid RNA-seq 
    Miller, Jason R.; Adjeroh, Donald A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)
    Background Parent-of-origin allele-specific gene expression (ASE) can be detected in interspecies hybrids by virtue of RNA sequence variants between the parental haplotypes. ASE is detectable by differential ...
