Abstract:
We have shown that inbreeding allows maternally transmitted organelles to respond to selection on male-specific fitness effects (Wade and Brandvain 2009, see also Unckless and Herren 2009). Hedrick (2011) confirms our results, but takes issue with our characterization of "inbreeding" at mitochondrial loci. The reason for this disagreement is straightforward-we define inbreeding as the process of mating between relatives, whereas Hedrick (2011) defines inbreeding as increased homozygosity at autosomal loci genome-wide, which occurs because of mating between relatives. Here, we insist that our definition is not incorrect, and highlight some benefits of our view.

Meiosis II
The timing and cell division patterns of meiosis differ between males and females. In male meiosis, the centrosomes are part of the formation of the meiotic spindle. However, in oocytes, including that of humans, Drosophila,...

Meiosis I
Prophase I is the most extended and complex step of meiosis I characterized by synapsis, chromosome pairing, and recombination of the homologous chromosomes. This process is facilitated by a proteinaceous structure called the...
