Ordered tetrad analysis
WebAug 3, 2024 · Learn what a tetrad in meiosis is, what chromosomes form tetrads, and when tetrad formation occurs. Understand the importance of tetrad in crossing over. Updated: … WebTetrad Calculator is designed for tetrad analysis and demonstrations. Unordered tetrads with four spores Use this mode to calculate the recombination frequency between two genes. The map distance between two linked genes are calculated according to the following formula: cM = 50 * (TT + 6 * NPD) / ( PD + NPD + TT ).
