A list of puns related to "Allele Frequencies"
This actually isn't a homework question, I need it for my job lol.
I have a gene that deleted with an allele frequency of 3%. Assuming Hardy Weinberg, I want to know how many out 1000 people would have at least one deleted allele.
This is what I try:
p^2 + 2pq + q^2 = 1000
p^2 + 2(.03)(.03) + .03^2 = 1000
p^2 = 1000 - 2(.03)(.03) + .03^2
I seriously have no idea :(, any help is appreciated.
Intuitively it seems like the number of ppl would be ~6% of 1000, but im not sure
(2 * .03) * 1000 + (.03 * .03 * 1000) ?
Like wtf? The whole problem didnβt even have a number thatβs related to allele frequency.
In particular I am referring to the apple maggot fly and its original, still-extant ancestors that only feed on hawthorns.
Can someone explain why there needs to be a roughly equal distribution of allele frequencies when looking at DNA for forensics and paternity cases?
Just curious as to whether we are able to measure this at a meaningful rate, and if so, which is changing fastest.
Not defending the holocaust btw just saying
Hi everyone! Basically I have 40 whole genome sequences and I want to come up with a way that I can calculate the allele frequencies of the variants within these individuals within this small cohort. Of course I can look in gnomAD to check allele frequency of the variants on a broader scale but I want the allele frequency to be specific to my small cohort and itβs unique genetic architecture.
I am quite new to bioinformatics so sorry if I donβt understand some of the concepts. As an end result I would like to create a site like gnomAD but just for mine (and my labs) use so that going forward if we identify a new variant we can check the allele frequency in our specific country (our country does not have a public genomics database like gnomAD).
I know 40 whole genomes is a very small number but itβs just a starting point and the hope is that we can increase the numbers in the future.
Any help/starting points would be hugely appreciated.
Thanks!
Can allele frequencies within tumour cells tell you whether specific variants are germline or somatic?
I have a tumour sample with an allele frequency 90%. Could that mean that the variant is only somatic, since if it was germline it'd be 100%?
