Non-Mendelian segregation and transmission drive of B chromosomes
JPM Camacho - Chromosome Research, 2022 - Springer
Selfish genetic elements (SGE) get a transmission advantage (drive) thanks to their non-
Mendelian inheritance. Here I identify eight steps during the reproductive cycle that can be …
