The final cross between two heterozygotes (Aa X Aa) would produce AA, Aa, and aa offspring in a 1:2:1 genotype ratio with the first two classes showing the (A) phenotype, and the last showing the (a) phenotype, thereby producing the 3:1 phenotype ratio. (wikipedia.org)
Incomplete dominance is one of the mechanisms for dominance among heterozygotes in which the dominant allele does not fully overpower the phenotypic expressions of the recessive one, and there is an intermediate phenotype within the heterozygote. (microbiologynote.com)
In quantitative genetics, when the heterozygous phenotype is exactly the same as (numerically) those of two homozygotes, it is considered to be there is no dominance. (microbiologynote.com)
Mendel reasoned that each parent in the first cross was a homozygote for different alleles (one parent AA and the other parent aa), that each contributed one allele to the offspring, with the result that all of these hybrids were heterozygotes (Aa), and that one of the two alleles in the hybrid cross dominated expression of the other: A masked a. (wikipedia.org)
Co-dominance is the method of dominance in some alleles in which both alleles of one gene within heterozygotes lack the recessive and dominant relationship and every allele is capable of a certain degree of expression phenotypic. (microbiologynote.com)
To avoid potential confounding by sample-to-sample differences in the quality and yield of RNA preparations, or by interindividual differences in trans -acting factors that influence the expression of CYP2A13 , we determined the relative expression of variant and wild-type (WT) CYP2A13 alleles in RNA samples from heterozygotes.

C282Y1
The frequency of the C282Y variant averages 7% in Northern European and North American White populations, resulting in a 0.5% frequency of homozygotes (of whom 38-50% will develop biochemical evidence of iron overload but only 28% of men and 1% of women will develop clinical symptoms).

Allele2
The variant allele was found at a frequency of 0.00311 in 152092 control chromosomes in the gnomAD Genomes database, including 3 homozygotes. (genebe.net)

Hemochromatosis1
H63D homozygotes do not develop hemochromatosis but may be at increased risk for amyotrophic lateral sclerosis, and carriers may be at increased risk for non-cardia gastric cancer. (mhmedical.com)
Serum3
More than 80% of patients with MPGN II are positive for serum C3 nephritic factor (C3NeF), an autoantibody directed against C3bBb, the convertase of the alternative pathway of the complement cascade. (findzebra.com)

Elevated erythrocyte sedimentation rates further increased the OR to 20.2 (95% CI, 9.5-43.0), elevated serum CRP levels to 27.7 (95% CI, 10.7-72.0), and smoking to 34.0 (95% CI, 13.0-88.6) for homozygotes compared with noncarriers without these determinants. (nih.gov)

Disease2
We further report that the frequency of A138G heterozygotes is significantly reduced in number in cohorts of patients with autoimmune Graves' disease or hepatitis B infection, whereas G138G homozygotes are absent from a cohort of Hashimoto's thyroiditis patients. (ox.ac.uk)
During a screening program conducted in a health appraisal clinic, classic multiorgan disease was detected in only 1 of 152 homozygotes. (medscape.com)
Diabetes2
The mutation also was associated with an increased risk of type 2 diabetes in heterozygotes, and with the development of diabetes early in adulthood in homozygotes. (medpagetoday.com)
They concluded that the findings may have implications for the treatment of metabolic syndrome and type 2 diabetes: "Activation of HSL with consequent generation of endogenous ligands for PPAR-gamma, RXR-alpha, or both, may serve as an alternative means of reversing dyslipidemia and glucose intolerance in the metabolic syndrome and type 2 diabetes.

Dominance2
Co-dominance may be considered to be not dominance in the sense that the heterozygote exhibits the characteristics from both homozygotes. (microbiologynote.com)
To begin, let's take a look at two forms of non-Mendelian genetics that deal with alternative forms of dominance. (biologydictionary.net)

Including the genotypic threat of KRAA - Q/R RRAA heterozygotes was present to become greater than the homozygotes for every theme. (pkc-inhibitor.com)
The chromosomal translocation generates a translocation-bearing altered insect population, the translocation-bearing altered insect population comprises translocation-bearing individuals that are translocation heterozygotes and translocation-bearing individuals that are translocation homozygotes for the chromosomal translocation, and the translocation-bearing individuals display a fitness that is greater than that of the wildtype (non-translocation-bearing) individuals when challenged in a condition in which a translocation-based drive occurs.
