One way of measuring genotype frequency is from phenotype frequency. Consider the case of 3 blood groups A, AB and B determined by two alleles IA and IB at a single locus. In a random sample of 1000 humans, the A group occurred in 210, AB in 450 and B in 340 individuals. The frequencies of the blood group phenotypes [...]
After reading this article you will learn about:- 1. Detection of Linkage Using F2 Data 2. Detection of Linkage Using Backcross (Testcross) Data. Detection of Linkage Using F2 Data: It may be recalled that when 2 genes are located on 2 different chromosomes, they assort independently and give rise to a typical 9:3:3:1 ratio in the F2 generation assuming complete [...]
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 [...]
