some alleles are dominant over others
Among subjects homozygous for the CYP1A2 allele, ADRbeta1 Gly389 allele carriers are reported to have a higher percentage of depression level increase when compared to Arg389 homozygotes subjects.
A strong selective sweep results in a region of the genome where the positively selected haplotype (the allele and its neighbours) are in essence the only ones that exist in the population.
Autosomal recessive diseases, however, require two copies of the deleterious allele for the disease to manifest.
Because it is possible to possess one copy of a deleterious allele without presenting a disease phenotype, two phenotypically normal parents can have a child with the disease if both parents are carriers (also known as heterozygotes ) for the condition.
CF develops when neither allele can produce a functional CFTR protein.
