The term allele is different from a genotype because an allele can be singular, but the alleles that an individual (diploid organism) has at a certain locus are called a genotype.

Genetic drift
In genetic crosses, the term "strain" refers to a specific genetic line or variety of organisms that are pure-breeding for certain traits. Strains can differ in their genetic makeup and can be used in breeding experiments to study inheritance patterns and gene expression.
allele
A genetic carrier has a dominant and a recessive version of an allele. Normally, the term genetic carrier is used in relation to genetic illnesses where two copies of the recessive allele cause that illness. Therefore, a carrier does not have the illness themself (as the dominant, non-disease allele is expressed over the recessive allele). However, they have the ability to create an offspring who has the double recessive genotype and therefore has the condition if they mate with another carrier or someone who is double recessive (who has the disease).
The term for all the types of alleles that exist in a population is called the "allele pool." This refers to the complete set of different alleles present in a population’s genetic makeup. The allele pool is important for understanding genetic diversity and evolutionary processes within that population.

The term you're looking for is "founder effect." It refers to a situation where a small population establishes a new colony which might have different allele frequencies from the original population due to the limited genetic variation carried by the founders.
A dominant allele is called dominant because it can express its trait in the phenotype even when only one copy is present, overshadowing the effect of a recessive allele. This means that if an individual has at least one dominant allele for a particular gene, the dominant trait will be observed. The term reflects the allele's ability to "dominate" the phenotype in genetic expression.
The term that defines the changes in allele frequency that have a significant impact in small populations is "genetic drift." Genetic drift occurs due to random sampling effects, where chance events can lead to substantial fluctuations in allele frequencies over generations. This phenomenon is particularly pronounced in small populations, where the loss or fixation of alleles can occur more rapidly compared to larger populations.
