viability The period of time an organism remains alive; often used to describe the length of time before a seed will fail to germinate.
population viability analysis (PVA)
A method of predicting whether or not a species will persist in a particular environment.
positional information ...
Experiments to date have demonstrated the viability of the approach for a variety of test sequences. Results obtained with HPLC analysis demonstrate coupling efficiencies as high as 99.5% under optimized conditions.
It sometimes does cause some loss of viability, so some modest impact on the behavior or lifespan of the vector. Oftentimes it's extremely subtle, and the vectors do just fine even with a bunch of viruses or bacteria living inside them.
Effects of chromosomal breakage and realignment: Quite often these types of changes do not affect the viability of the organism (the genes are still there; they're just in different places) but, in sexually reproducing species, ...
Zygote mortality / fertilisation occurs, but zygote fails to develop
Hybrid sterility / hybrid survives (viable) but is sterile and cannot reproduce (no meiosis)
Hybrid inviability / F1 hybrid has reduced viability: incomplete development ...
prostate gland A gland that is located near and empties into the urethra; produces a secretion that enhances sperm viability.
The cells are not damaged by the process. In fact, because the machine can be set to ignore droplets containing dead cells, the percent viability of the sorted cells can be higher than that in the original suspension.

While these advances have hugely benefited current populations, they have to a significant degree released the human species from the biological process which created it and maintains its viability.
Housekeeping gene A gene which is expressed at a similar level in almost all cells, presumably because its product is required for cell viability.
It can be seen as the extent to which an individual successfully passes on its genes to the next generation. It has two components: survival (viability) and reproductive success (fecundity).
sperm cells - moving them towards the lumen of the semiferous tubule as they develop until maturity when they are released. The Sertoli cell also reduces motility and capacitation (initiation of the acrosome reaction) of the sperm cells so viability ...
