Zygosity - Wikipedia, the free encyclopedia
Zygosity refers to the similarity of genes for a trait (inherited characteristic) in an organism. If both genes are the same, the organism is homozygous for the trait. If both genes are different, th...

Dominance (genetics) - Wikipedia, the free encyclopedia
In genetics, dominance describes a relationship between different forms (alleles) of a gene at a particular physical location (locus) on a chromosome. Typical plants and animals have two sets of chr...

homozygous Both alleles for a trait are the same in an individual. They can be homozygous dominant (YY), or homozygous recessive (yy). ... When the heterozygote has a different, intermediate phenotype compared to the homozygous dominant or homozygous recessive individuals, this is said to be incomplete dominance.

To date, only 3 patients confirmed to have homozygous dominant AIP (HD-AIP) have been described (hydroxymethylbilane synthase genotypes R167Q/R167Q and R167W/R173Q). OBJECTIVE: To investigate the genetic, biochemical, clinical, and neuroradiologic features of a severely affected infant with HD-AIP.

So, if the pea plant has a homozygous dominant genotype, it has two dominant genes - TT. If the pea plant has a homozygous recessive genotype, it has two recessive genes - tt. Heterozygous - If an organism's genotype is heterozygous it has one dominant gene and one recessive gene.
