homozygous or 2 dominant or 2 recessive.
heterozygotes
A dominant trait is expressed when two different genes for the same trait are present.
Having the same genes for a specific trait means that individuals possess identical copies of the gene responsible for that trait. This may result in similar physical characteristics or behaviors. It can be influenced by both genetic inheritance from parents and environmental factors.
Chromosomes that look alike and carry genes for the same trait are called homologous chromosomes. The nucleus contains these chromosomes.
When the alleles present for a trait are the same, the genes are called homozygous. This means that both alleles for a particular gene are identical. Homozygous individuals can have either two dominant alleles (homozygous dominant) or two recessive alleles (homozygous recessive).
It would depend on if the dominant genes are the same or different. Say the dominant alleles were different. In this case, they are co-dominant. If they are the same and both dominant homosytus.
When two alleles differ from each other, such as Tt, it is called heterozygous, hetero meaning different. When alleles are the same (TT) it is called homozygous, homo meaning same.
