A bird's wing bone
The presence of homologous structures (for example, the bone structure in chimpanzee arms, human arms, and whale flippers) indicates that the species sharing that homologous structure share a common ancestor.
A homologous structure that is greatly reduced in size is known as a vestigial structure. These structures are remnants of organs or body parts that had a function in ancestors but are no longer used in modern organisms. Examples include the human appendix and the hip bones in whales.
The karyotype of the asexual organism would not contain homologous chromosomes
The ovaries.
== == Homologous provide evidence for evolution because it shows the similarities and how we evolved from the same ancestors

The human appendix (a small sac near the junction of the small and large intestine) is homologous to a structure called the "caecum", a large, blind chamber in which leaves and grasses are digested in many other mammals.http://scienceline.ucsb.edu/getkey.php?key=3246
A homologous structure to a human arm bone would be the forelimb bones in other mammals, such as the forelimb bones in a bat or a whale. These structures may have different functions (e.g. for flying or swimming), but they share a common evolutionary origin with the human arm bones.
Homologous add Perhaps to a human's foot.
Yes, the human forelimb is considered a homologous structure because it shares a common evolutionary origin with the forelimbs of other vertebrates. Despite variations in function and appearance, the underlying bone structure and developmental pathways are similar across species.
I learned about homologous and heterozygous structures in Biology.
