What is Variation?01:14

What is Variation?

18.6K
Apart from the measures of central tendency, distribution, outliers, and the changing characteristics of data with time, an important characteristic of any data set is its variation or spread. In some data sets, the data values are concentrated closely near the mean; in others, the data values are more widely spread out from the mean.
The range, standard deviation, standard error, and variance are the different measures of variation.
Range: The range is the difference between its maximum and...

Variation

8.0K
An important characteristic of any set of data is the variation in the data. In some data sets, the data values are concentrated closely near the mean; in other data sets, the data values are more widely spread out from the mean. The most common measure of variation, or spread, is the standard deviation, which is the square root of variance.
When independent and dependent variables are plotted on a scatter plot, the slope of a line is a value that describes the rate of change between the two...

Conservative Site-specific Recombination and Phase Variation02:53

Conservative Site-specific Recombination and Phase Variation

6.9K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...

Variation of Atmospheric Pressure01:18

Variation of Atmospheric Pressure

4.2K
Change in atmospheric pressure with height is particularly interesting. The decrease in atmospheric pressure with increasing altitude is due to the decreasing gravitational force per unit area as we move away from the surface of the earth.
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
Let p(y) be the atmospheric pressure at...

Comparing Copy Number Variations and SNPs02:26

Comparing Copy Number Variations and SNPs

18.8K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Coefficient of Variation01:10

Coefficient of Variation

8.7K
The coefficient of variation measures the dispersion of the data points or distribution around the mean. Using the coefficient of variation, we can compare two data series with drastically different means or different units of measurement. The coefficient of variation for a sample and a population is expressed as a percentage of the ratio of standard deviation to the mean.
The coefficient of variation is a practical statistical tool in finance. It allows investors to assess the volatility or...

Area of Science:

  • Developmental Biology
  • Evolutionary Biology
  • Quantitative Genetics

Background:

  • Quantitative genetic variation in morphology drives species evolution.
  • Measuring adult form is increasingly combined with developmental studies.
  • Understanding developmental contributions to adult morphology is crucial.

Purpose of the Study:

  • To compare developing wing shape with adult form in *Drosophila melanogaster*.
  • To identify when genetic variation influences wing shape during development.
  • To establish a framework for analyzing morphological variation in developing fly wings.

Main Methods:

  • Protein expression patterns were used to measure shape in developing wing precursors.
  • Three developmental stages (larval, pupal, adult) were analyzed.
  • Wild-type and mutant (*shf*, *ds*) *Drosophila melanogaster* were studied.

Main Results:

  • Consistent differences in wing shape and size were found between genotypes at each developmental stage.
  • Linear rules were derived to link larval and pupal wing morphology.
  • The study quantified developmental contributions to adult wing morphology.

Conclusions:

  • The developed framework aids in analyzing quantitative morphological variation during fly wing development.
  • This approach helps characterize natural variation in larval and pupal wing shape.
  • It measures the contribution of developmental processes to adult morphology variation.
