>Scientists at the University of New South Wales discovered that, for fruit flies at least, the size of the young was determined by the size of the first male the mother mated with, rather than the second male that sired the offspring.

>“Our new findings take this to a whole new level – showing a male can also transmit some of his acquired features to offspring sired by other males,” she says.

>The researchers found cells with Y-chromosomes in the mother after these births, meaning the mother had male cells present in her female body. The researchers also found genetically similar male cells in the mother’s female puppies from a later litter. Those puppies were newborn and had never been pregnant, strongly suggesting that they acquired the cells that were left behind by their older brothers while in the womb.

Any biofags want to weigh in on this?

they are making a conclusion from the statement:
"Scientists have proved that, in fruit flies at least, offspring can resemble a mother’s previous mate"

I don't really know if it's clickbait or they truly believe that taking flies as examples is accurate.

>But the birth of genetics dismissed ‘telegony’ as a superstition which had no basis in science.
>This particular mechanism would be unlikely to apply to mammals such as humans because of differences in reproductive physiology compared to insects.
>“However, there is now evidence that so-called ‘epigenetic’ changes, can be passed down at least one or two generations, and such changes can be influenced by diet and other lifestyle differences.

Fetomaternal microchimerism
Stem cells from "pregnancy" from the first male help with later "pregnancies".
Stem cells enter woman from offspring. Later, these stem cells can enter a second litter.

Spermatazoa literally cannot get into any cell except an egg cell and survive.
And if it somehow got in a non-egg cell, the cell would not function and die, as a product of the acrosomes damaging the cell and resultant apoptosis, since eggs are designed to not get damaged from acrosomes, and are almost 100% the only cell type sperm can enter (due to receptors).

People claiming otherwise are retarded

Well, effectively in humans, a woman can have male stem cells from many male relatives, that pass through a chain of pregnancies from mother to daughter (or son, to end the chain).

You can't avoid getting "cucked", even with virgins, since they'll have these stem cells.

That said, I still prefer "pure" QT virgins

>The physiological persistence of fetal cells in the circulation and tissues of a previously-pregnant woman is called fetal cell microchimerism (FCM). It was hypothesized to play a role in systemic autoimmune diseases, but in autoimmune thyroid disease (AITD) only limited data are available.

>Circulating FCM was analyzed in a large series of previously-pregnant women with either Graves' (GD) or Hashimoto's (HT), or healthy (HC). To exclude the possible bias related to placental factors, the polymorphic pattern of human leukocyte antigen-G (HLA-G) gene, known to be involved in the tolerance to fetal cells by the maternal immune system, was investigated.

>The higher prevalence of FCM in HC than in GD and HT patients suggests a possible protective role in autoimmune thyroid disorders. Placental factors have been excluded as determinants of the differences found. The vascular and tissue localization of microchimeric cells further highlights their ability to migrate to damaged tissues.

> Fetal cell microchimerism (FCM) is defined as the persistence of fetal cells in maternal organs and circulation without any apparent rejection and it was hypothesized to protect toward the onset of some neoplastic diseases. To verify the role of FCM in papillary thyroid cancer (PTC), we enrolled 87 parous women with PTC and at least one male pregnancy preceding the diagnosis (PTC-P), 66 healthy women with 1 or more male children (HC-P) and 57 nonparous women with PTC (PTC-NP). The presence of circulating male DNA was assessed by the amplification of the Y chromosome-specific gene SRY, with a sensitivity of 1 male cell/1 million female cells. A significantly higher frequency of FCM was found in HC-P than PTC-P women (63.6% vs. 39.1%, p=0.004). Among PTC-P patients, those positive for the presence of FCM (FMC+ve) had a lower prevalence of extrathyroidal extension (p=0.027) and lymph node metastases (p=0.044) than those without FCM (FMC−ve). Moreover, FMC+ve patients were more frequently in remission than FMC−ve cases (94.1 vs. 67.9%, p=0.009). Interestingly, we showed for the first time that the positive effect on tumor presentation and outcome is specifically related to FCM and it is not an effect of pregnancy. In conclusion, circulating FCM is significantly more frequent in healthy parous women than in women with PTC. Moreover, the presence of circulating fetal male cells is associated with a significantly lower extrathyroidal extension and a good prognosis, suggesting a protective role of this phenomenon toward both the onset and the progression of thyroid cancer.

>It means that there's something going on in fruit flies that we don't understand yet.

The most commonly studied type of fly is D. drosophila (Dd from here).

Dd has somehow managed to evolve almost entirely around mating as its primary driving force behind natural selection. The male has spikes on its dick that literally rip semen from the vagina of the male, it can do this for hours. Females have evolved a type of false plug to trick males in to thinking it's currently laying eggs so the male leaves the female alone, but it doesn't always work. The sperm cells in a fruit fly are fucking huge, about 2mm long, for reference the resolution of the human eye is about 0.5mm and we can't see bacteria.

tldr fruit flies are fucking crazy when it comes to sex and using them as a model for anything related to sex in humans is not appropriate.

It means that women who get pregnant with male children become genetically male to a very small degree.
