Heritability is a statistic used in the fields of breeding and genetics that estimates the degree of variation in a phenotypic trait in a population that is due to genetic variation between individuals in that population. [ 1] The concept of heritability can be expressed in the form of the following question: "What is the proportion of the ...
For medical use, see body shape. Bust/waist/hip measurements (informally called 'body measurements' or ′vital statistics′) are a common method of specifying clothing sizes. They match the three inflection points of the female body shape. In human body measurement, these three sizes are the circumferences of the bust, waist and hips; usually ...
Punnett squares for each combination of parents' colour vision status giving probabilities of their offsprings' status, each cell having 25% probability in theory. The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment.
In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression.The process of finding or using such a code is Huffman coding, an algorithm developed by David A. Huffman while he was a Sc.D. student at MIT, and published in the 1952 paper "A Method for the Construction of Minimum-Redundancy Codes".
An autosome is any chromosome other than a sex chromosome. In genetics, dominance is the phenomenon of one variant ( allele) of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome. [1] [2] The first variant is termed dominant and the second is called recessive.
t. e. A person's waist-to-height ratio ( WtHR ), occasionally written WtHR or called waist-to-stature ratio ( WSR ), is defined as their waist circumference divided by their height, both measured in the same units. It is used as a predictor of obesity-related cardiovascular disease. The WHtR is a measure of the distribution of body fat.
v. t. e. Body mass index ( BMI) is a value derived from the mass ( weight) and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m 2, resulting from mass in kilograms (kg) and height in metres (m). The BMI may be determined first by measuring its components by means ...
By performing a test cross, one can determine whether the individual is heterozygous or homozygous dominant. [ 1] In a test cross, the individual in question is bred with another individual that is homozygous for the recessive trait and the offspring of the test cross are examined. [ 2] Since the homozygous recessive individual can only pass on ...
