hominis specimens were used for calculation of haplotype diversity (Hd), number of haplotypes, number of polymorphic and segregating sites, intragenic linkage disequilibrium (LD), and intragenic recombination rates by using DnaSP version 5.
An intragenic recombination test identified 26 potential recombination events (Rms) at the gp60 locus and no recombination at the remaining loci (Table 2).
Premawansa et al (11) have reported the presence of third type of allele in Sri Lankan isolates which had, Sal-1 like block immediately followed by variable numbers of glutamine repeats which were followed by a Belem like sequence indicating that this allele originated as a result of intragenic recombination.
However, we found larger numbers of other allelic types (types 1 & 2), probably due to frequent intragenic recombination in P.
The main cause of protanopia and deuteranopia lies in the unequal intergenic and intragenic recombination of the L- and M-cone pigment genes.
55,56) The composition of the hybrid gene, and therefore the peak sensitivity of the photopigment will be determined by the position within the gene at which the intragenic recombination takes place.
Marshall et al (25) and Eisen et al (31) also found the evidence of intragenic recombination in ama-1 gene.
The presence of size variation may result from the addition or deletion of the nucleotides in the msp-2 gene among the isolates, which may occur during multiplication of parasite or during intragenic recombination at the time of crossing over during meiosis within mosquito vectors (42).
was evident within ospC sequences.
between porin genes of the same allelic family is likely occurring in nature because mosaic gene structure has been reported in porB genes.
Several mechanisms, such as point mutations, intragenic recombination
, and introduction of foreign (African) alleles, were shown to enhance strain diversity within the family.
At the same time, intragenic recombination
was not detected at the intergenic spacer locus with Sawyer's test (www.
