2. Allele frequency - Wikipedia

   en.wikipedia.org/wiki/Allele_frequency

   Allele frequency. Allele frequency, or gene frequency, is the relative frequency of an allele (variant of a gene) at a particular locus in a population, expressed as a fraction or percentage. [1] Specifically, it is the fraction of all chromosomes in the population that carry that allele over the total population or sample size.

3. Half-life - Wikipedia

   en.wikipedia.org/wiki/Half-life

   Half-life (symbol t½) is the time required for a quantity (of substance) to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive. The term is also used more generally to characterize any type of exponential (or, rarely ...

4. Bovine serum albumin - Wikipedia

   en.wikipedia.org/wiki/Bovine_serum_albumin

   Bovine serum albumin (BSA or "Fraction V") is a serum albumin protein derived from cows. It is often used as a protein concentration standard in lab experiments. The nickname "Fraction V" refers to albumin being the fifth fraction of the original Edwin Cohn purification methodology that made use of differential solubility characteristics of plasma proteins.

5. Dice-Sørensen coefficient - Wikipedia

   en.wikipedia.org/wiki/Dice-Sørensen_coefficient

   Equivalently, the index is the size of the intersection as a fraction of the average size of the two sets. When applied to Boolean data, using the definition of true positive (TP), false positive (FP), and false negative (FN), it can be written as

6. Heritability - Wikipedia

   en.wikipedia.org/wiki/Heritability

   Heritability measures the fraction of phenotype variability that can be attributed to genetic variation. This is not the same as saying that this fraction of an individual phenotype is caused by genetics. For example, it is incorrect to say that since the heritability of personality traits is about 0.6, that means that 60% of your personality ...

7. Partial fraction decomposition - Wikipedia

   en.wikipedia.org/wiki/Partial_fraction_decomposition

   Partial fraction decomposition. In algebra, the partial fraction decomposition or partial fraction expansion of a rational fraction (that is, a fraction such that the numerator and the denominator are both polynomials) is an operation that consists of expressing the fraction as a sum of a polynomial (possibly zero) and one or several fractions ...

8. Mathematical and theoretical biology - Wikipedia

   en.wikipedia.org/wiki/Mathematical_and...

   Theoretical biology focuses more on the development of theoretical principles for biology while mathematical biology focuses on the use of mathematical tools to study biological systems, even though the two terms are sometimes interchanged. [ 3 ][ 4 ] Mathematical biology aims at the mathematical representation and modeling of biological ...

9. Fraction - Wikipedia

   en.wikipedia.org/wiki/Fraction

   A unit fraction is a common fraction with a numerator of 1 (e.g., ⁠ 1 / 7 ⁠). Unit fractions can also be expressed using negative exponents, as in 2 −1, which represents 1/2, and 2 −2, which represents 1/(2 2) or 1/4. A dyadic fraction is a common fraction in which the denominator is a power of two, e.g. ⁠ 1 / 8 ⁠ = ⁠ 1 / 2 3 ⁠.
