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.
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.
Alleles
recessive
Chromosomes that look alike and carry genes for the same trait are called homologous chromosomes. The nucleus contains these chromosomes.
Their offspring will have dominant genes. However, if these offspring have offspring with an amimal with recessive genes, the recessive genes will show up.
homozygous or 2 dominant or 2 recessive.
A dominant trait is expressed when two different genes for the same trait are present.
