Isolated populations can lose genetic diversity through genetic drift. This is because some alleles can be lost by chance. Many more homozygous individuals are likely.

Gene therapy
AnswerThe three types of genetic engineering are:Applied genetic engineering which includes cloning and transgenesis.Chemical genetic engineering which includes genes mapping, gene interaction, and genes codingAnalytical genetic engineering which includes computer mapping.
They have extremely short generation times and large populations. They can exchange DNA with many types of prokaryotes by way of horizontal gene transfer

There are two main types of genetic drift: population bottleneck and founder effect. Population bottleneck occurs when a population's size is drastically reduced, leading to a loss of genetic diversity. Founder effect occurs when a small group of individuals establishes a new population with limited genetic variation.
There are two types of genetic drift, there is a the population bottle neck effect and the founder effect. The population bottle neck effect is when a population greatly decreases in size due to some random ecological event and the small population has a greater chance of genetic variation. The founder effect is a variation of the bottle neck effect in which a small portion of a larger population to branch off or get "isolated" from the larger population and have a greater chance of genetic variation. Have fun and hope this helps.
Genetic drift is change in allele frequencies due to random chance events. Two types are the Founder effect and the Bottleneck effect. The founder effect is when a subset of a population goes to a new are where there are no other of that same species. The bottleneck effect is when a large population is reduced to a small population. Genetic drift decreases variation in a population and has a greater effect on a smaller population than a larger one.
motion and natural selection and genetic drift.
Genetic drift occurs in all finite populations. However the effects of drift are more pronounced in smaller populations than in large ones. Meanwhile, even though they are more present in smaller populations, the drifting is more likely to occur in larger populations because of the larger number of different genetic combinations present. Throughout evolution of populations, genetic drifting effects all types of population sizes, though it is more likely in larger populations but more present in smaller populations.
Founder effect- isolation of few individuals from larger population; new population forms with different gene pool. Bottleneck effect- Drastic reduction of population size leading to a restrictive gene pool in wich the population must use to recover. Forms population with different gene pool.

There are a few types of congenital diseases. The term is used for any condition that is a result of a genetic abnormality. There are ones that are sex linked and affect males more than females, and then there are the ones that affect both equally.
Till and stratified drift :D Did you get this from Portola MS in 6th grade workbook for Science?
A genetic mutation is a change in the DNA sequence that can affect an organism's traits. The types of genetic mutations include point mutations (substitution, insertion, deletion), frameshift mutations, and chromosomal mutations (deletion, duplication, inversion, translocation).
by the rate of population, types, habitats, and the numbers decreasing.
It could be that the people who first colonized Peru happened to mostly be type O (about 35% of people are), and the A and B types (which would have been very rare in the population) worked their way out over many generations. This is known as Genetic Drift, more specifically the Founder effect
