After reading this article you will learn about the estimation of similarities between two individual taxa. The similarity data is used to estimate distance between two individual taxa. The illustrated example taken from Henry (1997) is as follows: Let us say we have data from RAPD results for 2 samples A and B. Similarity (F) can be calculated as Similarity [...]
After reading this article you will learn about:- 1. Determination of Recombination Value from the F2 Data 2. Determination of Recombination Value from Backcross (Testcross) Data. Determination of Recombination Value from the F2 Data: Four methods are available to estimate recombination value from the F2 data. For each of these methods, the F2 data given earlier to detect linkage is [...]
Polyploids are defined as organisms with other than 2 basic sets of chromosomes, that is, monoploids, triploids, tetraploids, and various aneuploids. Segregation in polyploids differs from that in diploids due to the many different ways in which the chromosomes can pair in a polyploid and due to larger number of alleles segregating at each locus. Judging by the frequency with [...]
