This marine worm, first described in 1949 as an acoel flatworm and later claimed as either an early metazoan offshoot or a primitive deuterostome, has recently been affiliated with primitive bivalve molluscs, based upon a study of gamete development oogenesis and an analysis of sequence data from both 18S rRNA and mitochondrial genes.
Since the shell is secreted by the follicle cells during oogenesis, we expected the defect to depend on the genotype of those cells.
Drosophila oogenesis to come to rival embrogenesis as a ideal system for studying patterning.
The phenotypes suggested that the process of segmentation involves at least three levels of spatial organization: Processes beginning during oogenesis define the large unique regions requiring the gap gene function, the gap genes in turn control
Except in the very earliest stages of oogenesis there is no real similarity between the development of a Zoophyte, a Mollusc, an Articulate and a Vertebrate, but each is stamped from the beginning with the characteristics of its type.
During oogenesis, MAPs are believed to stabilize microtubules preferentially close to condensed chromosomes, favoring spindle assembly around DNA.
The network also highlighted a number of proteins and their complexes absent from the mitotic spindle proteome (MSP), suggesting that some of them may have a specific microtubule-related role during oogenesis.

The failure of Foxl2-negative granulosa cells to sustain follicle formation is a primary cause of ovarian failure, leading to subsequent deregulated oogenesis by an unknown mechanism
And we know a lot about spermogenesis and oogenesis.
