Many negative diseases and traits are very rare and recessive. In a population where very little inbreeding occurs, these negative traits do not show up frequently because such a small percent of the population is a carrier for them.
When related individuals who are carriers of these negative recessive traits breed with each other, their offspring receive two copies of the trait, resulting in the physical or mental retardation of the offspring due to the negative trait.

∙ 11y agoNo it does not because you would be getting the same exact cells that your family already had. You would only get variation when you have a mixture of unrelated cells.

Which procedure can not be used to increase genetic variation?
If a population dwindles, there is low genetic variation and a species may risk extinction.
Breeders can increase the genetic variation by inducing what?
The introduction of animals into a breeding population that are unrelated will increase genetic variation.
What increases genetic variations?
A large population increases genetics variation. Mutation will also increase genetics variation.
What tends to increase genetic variation in a population?
Genetic variation is the total amount of genetic diversity present within a species or population. The amount of genetic variation in a population will depend on a variety of factors, including the size of the population, the type of reproduction, and environmental influences. The primary way to increase genetic variation in a population is through mutation. Mutations are random changes in the genetic code that can lead to new traits or characteristics. Mutations can be caused by environmental factors, such as exposure to radiation or chemicals, or they can occur spontaneously. Mutations can be beneficial, neutral, or detrimental to the organism, but they do lead to increased genetic variation. Another way to increase genetic variation in a population is through migration. When individuals from different populations mate, they bring with them different alleles from their home population, increasing the genetic diversity of the new population. This is especially important for populations that are geographically isolated, such as island populations. Another factor that can increase genetic variation is sexual selection. This is the process by which individuals select mates based on certain desired traits. This can lead to an increase in the number of different alleles in the population, as individuals with certain traits will be more likely to reproduce. Finally, gene flow is a process that can increase genetic variation in a population. Gene flow is when individuals from one population move to another population and mate with individuals in the new population. This can bring in alleles from the original population, increasing the genetic diversity of the new population. Overall, while mutation, migration, sexual selection, and gene flow are all important factors in increasing genetic variation in a population, it is important to note that genetic variation can also be decreased by inbreeding and genetic drift. Inbreeding is when individuals mate with close relatives, reducing the number of alleles in the population and leading to decreased genetic variation. Genetic drift is when random fluctuations in allele frequencies occur due to a small population size, leading to decreased genetic variation. Therefore, it is important to consider all of these factors when trying to increase genetic variation in a population.
What causes many endangered species that are now found only in zoos to have very little genetic variations?
Founder effect refers to the loss of genetic variation when a new colony is established by a very small number of individuals from a larger population. As a result of the loss of genetic variation, the new population may be distinctively different.Bottleneck effect is an evolutionary event in which a significant percentage of a population or species is killed or otherwise prevented from reproducing, and the population is reduced by 50% or more, often by several orders of magnitude.Population bottlenecks increase genetic drift, as the rate of drift is inversely proportional to the population size.They also increase inbreeding due to the reduced pool of possible mates.

If a population dwindles, there is low genetic variation and a species may risk extinction.
What would decrease genetic variation in a population?
When there is low genetic variation in a population the species produced are unlikely to withstand diseases.
Breeders can increase the genetic variation by inducing what?
The introduction of animals into a breeding population that are unrelated will increase genetic variation.
What increases genetic variations?
A large population increases genetics variation. Mutation will also increase genetics variation.
What can the variation become?
The variation can either increase or decrease depending with the genetic factors.
How does bacteria increase genetic variation?
Well... when bacteria proform conjugation they trade some DNA which allows the to become anti-biotics and increase genetic variation

Are dog breeds produced by inbreeding or genetic engineering?
Inbreeding
What id genetic variation?
Genetic Variation is a measure of the genetic differences there are within populations or species. For example, a population with many different alleles at a locus may be said to have a lot of genetic variation at that locus. Genetic variation is essential for natural selection to operate since natural selection can only increase or decrease frequency of alleles already in the population
