Sequence analysis of alleles was examined for 34 samples. The sequence structures of the alleles were classified into three types: A, B and C. Type A had a regular repeat structure of the repeat region: (GAAA)n. Types A and B differed in the base sequence of the repeat region. As an...
SELECTION: GENERAL MODEL Recurrence equations Assume two sex-linked loci each with two alleles, A, a and B, b respectively. Let the population be censused at the gametic stage, then at time t the frequencies of the gametes are; AB Ab aB ab x,Females; x2 x31 x4 Males; Y1,t Y,i ...
If one parent is type A and the other type B, but all four blood types are represented among the children, what were the genotypes of the parents? What is a gene? What is an allele? Give an example of 2 alleles of a human gene. ...
Heterozygotes at this locus show a three-banded pattern typical of a dimeric enzyme. The relatively slight difference in mobility between the two slower alleles was not recognized in our earlier studies with this locus; in addition, *75/80 Ml A'A' AA' Male — 23 5 0.136*** Female — ...
The expression ofVviFSEXis detected in petals, stamens and carpel primordia of all flower types, making its putative function unclear; however, female plants display a single allele for this gene, while male and hermaphrodites display two alleles. On the other hand, the specific expression of...
The goal of these scripts is to simulate hybridization and recombination within populations to track the fate of alleles at two types of loci: pairs of loci that interact through epistasis and three loci taht additively affect fitness in the environment. As indicated in the wrapper scripts, ...

which showed significant heterozygote deficit for both forms, most likely due to null alleles which are known to be present at this locus [48]. All subsequent analyses are presented with this locus removed. The microsatellite FSTvalue between the two morphotypes in Florencia was large and significa...

The co-existence of males, females and hermaphrodites, a rare mating system known as trioecy, has been considered as an evolutionarily transient state. In nematodes, androdioecy (males/hermaphrodites) as found in Caenorhabditis elegans, is thought to hav
