An allele present in all members of a population
What else can I help you with?
What does it mean when an allele reaches fixation in a population?
When an allele reaches fixation in a population, it means that all individuals in the population carry that specific allele, and no other alleles for that gene are present. This can happen through natural selection, genetic drift, or other evolutionary processes.
What is the Random change in a populations allele frequency is known?
Genetic drift is the random change in allele frequencies in a population. It is caused by chance events and has more pronounced effects in small populations where genetic diversity is lower. Over time, genetic drift can lead to the loss of certain alleles or fixation of others in a population.
What are the changes of allele frequency in a small population that is due to random chance and don't follow the laws of probability?
Random changes in allele frequency are due to genetic drift.
What is allele masked by the dominant allele?
An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).
The evolutionary force that operates primarily through chance is?
genetic drift. This is the random fluctuation in allele frequencies in a population, which can lead to the loss or fixation of alleles over time due to random sampling during reproduction.

Is there any evidence that the traits shared by most of the population is not controlled by a dominant allele explain?
The presence of a dominant allele is not always required to explain common traits in a population. Polygenic inheritance, where multiple genes contribute to a trait, can lead to common traits without a dominant allele. Additionally, environmental factors can also play a significant role in shaping common traits among a population.

Allele that prevents the expression of a recessive allele?
A dominant allele
When does fixation mean?
And human growthwhen does fixation mean

What is the alternate form of a gene?
The answer is allele
An allele that is dominated or cover up by another allele is called what?
An allele that is dominated or covered up by another allele is called a recessive allele. This means that the trait associated with the recessive allele is only expressed when an individual carries two copies of that allele.
What is neuropexy?
Literallty means 'Nerve Fixation' Or 'Fixation of a Nerve'.
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
