Tajimas D And Fu And Li'S Neutrality Tests - P Values?!
... Hi there, I have used Tajima's D and Fu and Li's statistics to assess whether my sequencing data shows evidence of deviation from neutrality. (Using DNAsp software). The problem I have is that these tests do not give ACTUAL P values. So for Tajima's D, you get a D value and then P<0.05 for exa ...

Arlequin Linkage Disequilibrium - So Confused!
... Hi, I am looking at LD between a SNP in one gene and three SNPS that are in the neighbouring gene and I am using Arlequin to do so.. This is what is confusing me... SNPS 1 and 2 - derived alleles of SNP1 always occur with derived alleles of SNP2 (I can see this in the haplotypes) And..Arlequin t ...

Is Haploview The Best Method For Defining Ld Blocks?
... Hi all, I am working with haploview to view my data and get an idea on how much LD there is across my gene. Haploview gives three options for defining blocks of LD 1) confidence intervals -95% confidence bounds on D prime are generated and each comparison is called "strong LD", "inconclusive" or ...

Mantel Test, Arlequin..And How To Make Input Files
... hello everyone, Has anyone here used Arlequin to conduct a Mantel test? Or any other software to do so? I have pairwise Fsts for 19 populations. This has been done for the exons and introns of my genes. I want to see if there if there is a correlation between the pairwise fsts of the introns and ...

Ka/Ks Ratio For Within A Gene - Very Confused !!
... Hi, I am asking another ka/ks related question! I am a bit of a beginner with this stuff so go easy. I understand the the Ka/ks ratio is used mainly for interspecies comparisons..is a way of assessing what type of selection is acting on a gene. I know it is also usable for intraspecies comparison ...

Comment: C: Ka/Ks Ratio To Detect Selection (Nonsynonmous To Synonymous) In Dnasp
... Hi, thanks for your answer. I have calculated nucleotide diversity (pi) and gene diversity (h) but am still interested in the Ka/Ks ratio. So it should not make a difference if I put the intronic region between exons into the sequence or not. As technically these will be excluded anyway once I assig ...

Ka/Ks Ratio To Detect Selection (Nonsynonmous To Synonymous) In Dnasp
... hello everyone, I have sequencing data for my gene from >2000 individuals. I want to look at the Ka/Ks ratio of my coding regions to assess evidence of selection. I am aware that MEGA and DNAsp are good tools to find this out but I am confused as to what to provide the software. I would prefe ...
