In most cases, however, there can be multiple copies of the same gene, or multiple genes that are highly homologous, and these can be scattered along the length of the genome. Recently, Sankoff (1999) has proposed a method for estimating which o ...

CARRIER SCREENING FOR CYSTIC FIBROSIS

... When a person tests positive for CF trait, carrier screening for their partner is recommended. Remember, a couple is only at increased chance to have a child with CF if both members are carriers. If one member of the couple is a carrier, but the other member is not a carrier of one of the common mut ...

Ideally, estimates of these clinical measurements of genetic testing would come from large-scale population-based cohort studies; such studies, however, will take considerable time and resources. In this paper, we illustrate how clinical validation of new predictive genetic tests can be done ...

... throughout the organism may conceivably have deleterious effects on fitness (Liu et al., 1999). For this reason, SM1 expression was restricted to posterior midgut cells for only a few hours after a blood meal and the protein was secreted from the cells, thus minimizing fitness load. Absolute absence ...

The Genetic Code

... Codons that specify the same amino acid typically only dier by one nucleotide. In addition, amino acids with chemically similar side chains are encoded by similar codons. This nuance of the genetic code ensures that a single-nucleotide substitution mutation might either specify the same amino acid ...

Microevolution

Microevolution is the change in allele frequencies that occur over time within a population. This change is due to four different processes: mutation, selection (natural and artificial), gene flow, and genetic drift. This change happens over a relatively short (in evolutionary terms) amount of time compared to the changes termed 'macroevolution' which is where greater differences in the population occur.Population genetics is the branch of biology that provides the mathematical structure for the study of the process of microevolution. Ecological genetics concerns itself with observing microevolution in the wild. Typically, observable instances of evolution are examples of microevolution; for example, bacterial strains that have antibiotic resistance.Microevolution over time leads to speciation or the appearance of novel structure, sometimes classified as macroevolution. Macro and microevolution describe fundamentally identical processes on different scales.
