Q

What is a tumor ? Where is it found ? What kind of tumors are found in ovarian ? How ind of tumor testicular ?

What may it have ? Does it form functional structures ? What is its connection to parthenogenesis ?

A

a tumor composed of tissues not normally present at the site (the site being typically in the gonads).

Dick is far away out our body, so it mus be a malignant tumor

parthenogenesis: reproduction from an ovum without fertilization, especially as a normal process in some invertebrates and lower plants.

Endoreplication is the replication of DNA during the S phase of the cell cycle without the subsequent completion of mitosis and/or cytokinesis.
