In larger populations there is stronger selection against deleterious traits. The smaller the population, the greater the degree of deleterious traits are accepted.

What make small populations vulnerable to extinction?
there are several factors that make small populations vulnerable. First off there are demographic factors. If a small population faces a forest fire, they are more susceptible to extinction opposed to a large, wide-spread population. you also have the lack of genetic availability. without genetic variation, a species can become prone to disease. there are many more, and I could go on.
What small dog has the least heath problems?
Generally small dogs tend to have fewer health problems than larger dogs but they still have what tend to be genetic problems. Most purebred dogs are going to have more chance of genetic problems... if you want less chances of genetic and health problems look for a good mix that fits your lifestyle. The cross breeding tends to breed genetic issues out.
What are the Yorkshire terriers strengths and weaknesses?
Strengths of Yorkshire terriers include their cute look, they are loveable, loving, and smart. Weaknesses include their small size which leaves them prone to injuries such as broken bones. They also have several health issues that they are prone to.
Can a son get a mother hamster pregnant and at what age?
Oh, yes they can. It's rarely a good thing. Small animals like hamsters are already more prone to genetic abnormalities (high prevalence of tumors, etc) and inbreeding exacerbates those problems. Inbreeding can result in extra or missing fingers, toes, or limbs, behavioral problems, or still birth.
What are 3 reasons why lions are endangered?
The African lion is considered Vulnerable by the IUCN. The causes are primarily human conflict with lions, habitat loss, disease, and fragmentation of lion habitat (small populations becoming isolated because of human development cutting them off from other populations). The Asiatic lion is considered Endangered by the IUCN, and the causes are hunting (back over 100 years ago they were nearly completely wiped out by hunting), and possibly habitat loss.

Does genetic drift occur in small or large populations?
Small populations.
Where is genetic drift most noticeable?
In small, isolated populations.
When is genetic drift least likely to occur?
Small populations
Genetic drift is most likely to occur in?
small populations
What type of population is most susceptible to loss of genetic variability as a result of genetic?
small populations
What type of population is most susceptible to loss of genetic variability as a result of genetic drift?
small populations
Why are small populations difficult to preserve?
Small populations are difficult to preserve because they are more vulnerable to genetic problems like inbreeding, disease outbreaks, and environmental fluctuations. With fewer individuals, there is less genetic diversity to adapt to changing conditions and higher risk of losing unique traits. Additionally, small populations are more susceptible to catastrophic events that can wipe out the entire group.
What statistical rule does genetic drift follow in small and large populations?
In small populations, genetic drift follows the rule that genetic variation can change quickly due to random sampling effects, which can lead to loss of alleles and increased genetic homogeneity. In large populations, genetic drift is less pronounced due to the dilution effect of larger sample sizes, which helps maintain higher levels of genetic diversity over generations.
What may rare genetic disorders become common in small populations through?
This can occur through reproduction. If you have two people with the recessive gene for a rare genetic disorder, they have a 25% chance of having offspring with this disorder. The probability increases as the genetic pool increases.
What term defines chance changes in our life frequency that have a big effect in small populations?
This is the random process called genetic drift.
Do alleles behave the same way no matter what the population size is?
In small populations, genetic drift can have a greater impact on allele frequencies, leading to more rapid changes than in large populations where genetic drift has a smaller effect. Additionally, in small populations, the effects of genetic drift can increase the likelihood of alleles being lost through random sampling.
