WebFour major forces are usually listed for changing gene frequencies in populations, namely migration, mutation, selection and random genetic drift. These forces constitute the mechanisms underlying the evolutionary process. 1. Migration: Migration occurs when a large influx of people moves into another population and interbreeds with the latter. WebTwo types of heterogeneity are recognized: genetic heterogeneity and allelic diversity. Genetic heterogeneity can be defined as mutations at two or more genetic loci that produce the same or similar phenotypes (either biochemical or clinical). This is relevant since genetic heterogeneity can present problems for heterozygote detection.
WebThe gene–environmental interaction or gene–gene interaction may also play a role in ovarian cancer risk. Conclusion We found that the allelic and recessive models of ESR2 rs1271572 and the dominant model of ESR2 rs3020450 might be susceptible factors in ovarian cancer.
