Heterozygous refers to genotypes in which the alleles for a given trait are different. What is an example of a homozygous trait? Homozygous refers to a zygote or organism that has a genotype for a certain trait where all of the organism's alleles for that trait are identical. For example,...
Similarly, those homozygous for the N allele have the N antigen on their red blood cells. Heterozygotes—those with both alleles—carry both antigens. An example of codominance for a gene with multiple alleles is seen in the human ABO blood group system. Persons with type AB blood have one...

aa Homozygous recessive Aa Heterozygous Dominant alleles are designated with a capital letter (ex: A). Recessive alleles are designated with a lowercase letter (ex: a). In Mendelian genetics, genes containing at least one dominant allele (AA, or Aa) will express the phenotype of the dominan...
Locus: The specific location a gene has on a chromosome. Heterozygous: an offspring that obtains two different alleles of one gene in particular. Homozygous: An offspring that obtains the same alleles of a particular gene from both parents. ...
A gene is nothing but a template for creating an enzyme. This means that, in any plant or animal, there are actually two templates for every enzyme. In some cases, the two templates are the same (homozygous), but in many cases the two templates are different (heterozygous). ...

The incomplete dominance concerns the production of heterozygotes that possess intermediate traits between the two homozygous traits. These heterozygous organisms have phenotypes that are a blend of the phenotypes of their homozygous traits. The trait developed is neither dominant nor recessive. Therefore,...
The first type of square is the 2×2 square composed of four boxes. This type of square is used for amonohybrid cross. In a monohybrid cross, a single genetic trait or character is studied by crossing two homozygous dominant and recessive parents for the said character. ...
Two parental taxa are homozygous in this case for different alleles at C and D loci, whereas F1 hybrids will be heterozygous for these alleles at two diagnostic loci. However, when hybridization proceeds further than the F1 stage, hybrid descendants will give a broad mixture of recombinant ...
