Interestingly, the combination of a high migration rate (μ=15) and a low progeny proliferation capacity leads to a qualitative change in the behaviour of the population.
The criteria for culling of females are: failure to conceive before 2 years of age, inability to conceive in any subsequent year, and low progeny performance.

Here we challenge this assumption, reasoning that D. discoideum genotypes could potentially produce large numbers of small, low-quality progeny (i.e., small spores with relatively low viability) or invest in smaller numbers of larger but higher-quality progeny (i.e., larger spores with higher viability).
The randomness of recombination, which potentially produces low fitness progeny, contradicts notions of fitness landscape hill climbing.
A higher SOD1 transcript was observed in islets from 3 month-old low protein progeny whereas SOD2 was slightly increased only in LPT islets (Figure 5A/B).
Due to the low frequency, progeny with complete removal of Neo cassette were often not detected until second or third round of mating, which will take additional 3 6 weeks.
Our model predicts that the low dormant progeny will enter a rapid cycle if the climate permits, flowering and setting seed later the same summer.
The same was true for 21B4 except for one tetrad where one high, two medium and one low expressing progeny were found, suggesting that two closely linked mutations might be responsible for the high ARS activity phenotype.
High genetic relatedness within expanding populations indicates original colonization by a few individuals and population expansion by the recruitment of the original colonists' progeny; low relatedness should occur if population growth results primarily from continuous seed immigration from multiple sources.
Hand-pollination experiments also confirmed the low viability of progeny originating from backcross pollinations [ 11, 12].
HMGA1 expression is high in undifferentiated human ESCs/iPSCs (and low in differentiated progeny) and in human CD34+ hematopoietic cells (and low in CD34– cells).

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
