Mean anomaly, a measure of time in the study of orbital dynamics Pioneer anomaly , the observed deviation of the trajectories of some uncrewed space probes, and especially Pioneer 10 and Pioneer 11 South Atlantic Anomaly , an area where the Earth's inner Van Allen radiation belt comes closest to the Earth's surface
In the natural sciences, especially in atmospheric and Earth sciences involving applied statistics, an anomaly is a persisting deviation in a physical quantity from its expected value, e.g., the systematic difference between a measurement and a trend or a model prediction. [1]
A chromosomal abnormality, chromosomal anomaly, chromosomal aberration, chromosomal mutation, or chromosomal disorder is a missing, extra, or irregular portion of chromosomal DNA. [ 1 ] [ 2 ] These can occur in the form of numerical abnormalities, where there is an atypical number of chromosomes, or as structural abnormalities, where one or ...
Genetic disorders may also be complex, multifactorial, or polygenic, meaning they are likely associated with the effects of multiple genes in combination with lifestyles and environmental factors. Multifactorial disorders include heart disease and diabetes. Although complex disorders often cluster in families, they do not have a clear-cut ...
The great plate count anomaly. Counts of cells obtained via cultivation are orders of magnitude lower than those directly observed under the microscope. This is because microbiologists are able to cultivate only a minority of naturally occurring microbes using current laboratory techniques, depending on the environment.

About 3% of newborns have a "major physical anomaly", meaning a physical anomaly that has cosmetic or functional significance. [20] Congenital disorders are responsible for 20% of infant deaths. [21] The most common congenital diseases are heart defects, Down syndrome, and neural tube defects. Trisomy 21 is the most common type of Down Syndrome.
Chromosomal reciprocal translocation of the 4th and 20th chromosome.. In genetics, chromosome translocation is a phenomenon that results in unusual rearrangement of chromosomes.
