The alleles in question were found on two
different haplotypes — a set of alleles inherited by an individual from a single parent — in unrelated individuals.
Not exact matches
Persons B and D share a
haplotype unlike the other three, characterized by three
different DNA bases.
Yet there were numerous
different subclone
haplotype — one came to dominate, but the others persisted as well.
By sequencing the DNA of
different croc populations, the researchers discovered that the Abanda cave crocs were inheriting their own unique
haplotypes, the term for a group of genes that one parent passes to its offspring, according to National Geographic.
We did however identify two regions where distinct
haplotypes have swept in
different populations, leading to increased population differentiation.
As a consequence, the possibility has been raised that admixture did occur, but the early Europeans of modern anatomy were not too
different genetically from Neandertals, or else that most Neandertal
haplotypes were lost through a process of lineage sorting, i.e. by genetic drift [5].
Specific assortments of MHC alleles, comparable to 7 beads of
different colors on a string, constitute a
haplotype.
Doing a genetic test and subsequently eliminating an individual from the breeding population may not be the best strategy, as by targeting a particular allele at one genetic locus for removal from the gene pool of a particular breed, breeders may in fact increase allele frequency of genetic variants on alternative
haplotypes at the same, or a
different locus, that are recessively deleterious.
The low number of
different DLA class I and II
haplotypes in English bulldogs was associated with an imbalance in the relative frequency of each
haplotype.
This pattern is strikingly
different from the southern islands, where San Clemente and San Nicolas each have two
haplotypes just a single base pair away from each other.
