The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.

EvolGenius is a two-locus population genetics simulation written for use ... This includes which allele (if either) is fixed; the allele and gene copy fixation times; the final frequencies of ...

Homozygous: The alleles at a genetic locus are identical. An individual who has blood type O (genotype OO) is homozygous for the O allele. Karyotype: Under a microscope, chromosomes can be ...

Similar genes occupy the same position on both chromosomes in the pair. Alleles can be dominant or recessive. Dominant alleles will be expressed even if a recessive allele is present. Recessive ...
