idiogramFISH (version 1.5.1)

asymmetry: Function to calculate karyotype asymmetry A and A2

Description

This function reads a dataframe with columns: shortArmSize and longArmSize

If several species present, use column OTU.

It returns a list with the A and A2 indices

A2 = sCL / xCL (s = std dev, CL= chr. length, x= mean)

related to: CVCL= A2 *100 (CV = coeff. var.)

A: Watanabe et al. (1999) asymmetry of karyotype ranging from 0 (symmetric) to 1 (asymmetric)

Usage

asymmetry(dfChrSize)

Arguments

dfChrSize

name of dataframe

Value

list
