Single queen colonies of the narrow headed ant " Formica exsecta " illustrate the possible deleterious effects of increased homozygosity.
32.
These negative effects are likely due to the increased homozygosity that arises from inbreeding and the consequent expression of deleterious recessive mutations.
33.
The largest genetic differences within the Netherlands are observed between the North and the South ( with the three homozygosity levels ).
34.
As homozygosity increases, less fit individuals will be selected against and thus those harmful alleles will be lost from the population.
35.
As his parents were first cousins, the presentation of dysmorphic features is conjecturally linked to confounding homozygosity at additional recessive loci.
36.
By taking into consideration the population allele frequencies for all SNPs via autozygosity mapping, the results of homozygosity can be confirmed.
37.
The effective number of alleles " n " maintained in a population is defined as the inverse of the homozygosity, that is
38.
Being heterozygous for this Arg83Gly variant increases the risk of heart failure by 27 %, while homozygosity increases the risk by 54 %.
39.
This increases the frequency of homozygosity of harmful recessive genes in the population and in turn, increases the co-efficiency of inbreeding.
40.
Reduced colony survival appears to be due to decreased queen lifespan resulting from queen homozygosity and expression of deleterious recessive mutations ( inbreeding depression ).
