Haplotypes

The limits of using mtDNA for determining who is more closely related to whom is that there are a limited number of haplotypes present in a population compared to the total number of indivduals in the population. Two individuals might have the same mtDNA sequence, which means that ...

... how closely related they are - within limits. Barring new mutations, mtDNA within any species will exist in a limited number of different haplotypes (mtDNA is haploid). That is, there are a limited number of different sequences of the mtDNAs within a species. All individuals differ in ...

... L in gene 3 on the maternal chromosome have the AHL haplotype. Maybe the paternal chromosome has SNP R in gene 2, so its haplotype would be ARL. Haplotypes don't have to be the entire chromosome, though. They are just the collection of the different polymorphisms at different loci that are all ...

I'm reading a paper on the pseudogenization of certain genes through gene conversion, but the paper contains some terminology that I'm a little new to, and neither the internet or my book seem to give a very good explanation of it. So could anyone give me a general idea about what intragenic and int...

... positive selection in the lineage leading to Homo sapiens (Zhang, 2003; Evans et al, 2005). Within modern humans a group of closely related haplotypes, known as ‘haplogroup D’ arose from a single copy at this locus (Evans, 2006). Globally, D alleles are young and first appeared about 37,000 ...
