Use Response To Selection when you need to compute the breeder's equation response to selection as heritability times the signed selection differential. Enter Heritability and Selection differential using the definitions and units below so the result can be reproduced.

Heritability

A finite measured or assumed value from 0 through 1.

Selection differential

Signed difference between selected parents mean and population mean.

The published tool contract uses this rule: Compute the breeder's equation response to selection as heritability times the signed selection differential.^[1]

Response to selection

The calculated response to selection.

The calculation does not propagate measurement uncertainty, sampling error, or biological and chemical variability. Heritability must remain between 0 and 1.

Retain the original Heritability and Selection differential values and their units alongside the result. Selection Differential is useful when you instead need to compute the signed selection differential as the mean of selected parents minus the population mean. Selection Intensity i provides another view by helping you compute the standardized selection intensity as the signed selection difference divided by the phenotypic standard deviation.

• Selection Differential

  Compute the signed selection differential as the mean of selected parents minus the population mean.

• Selection Intensity i

  Compute the standardized selection intensity as the signed selection difference divided by the phenotypic standard deviation.

• Selection Coefficient

  Compute the selection coefficient s = 1 - w from a relative fitness w between 0 and 1.
