A trait shared by at least two and perhaps more taxa and devolving on common ancestry is synapomorphy. A homologous trait is quite similar. The forelimbs of all tetrapods are devolved from common ancestry and would be traits shared by many taxa and homologous traits. Cladists use the word synapomorphy more to show closer relationships. Pliesiomorphy is the word cladists use to show more ancient relationships.
Homozygous or purebred
homologous
Chromosomes that look alike and carry genes for the same trait are called homologous chromosomes. The nucleus contains these chromosomes.
A discontinuous trait is the opposite of a continuous trait. They are "either/or" traits that do not have any range. An example would be the sex of an offspring, whereas an example of a continuous trait would be haircolor, where many options are available.
Homozygous Homozygous
It's a trait common in a single monophyletic group,but not generally found outside of that group.
Homozygous or purebred
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
Homologous pairs
Homologous structures
A trait that is produced from two alleles is a Homologous.

A single-gene trait is a phenotypic trait controlled by two homologous alleles.
A cell is said to be homozygous for a particular gene when identical alleles of the gene are present on both homologous chromosomes. For example, if the alleles are AA or aa the cell is homologous for that trait. It is heterozygous if it is Aa
