It would not be safe to assume that the synapsid temporal fenestra is strictly homologous to the lower temporal fenestra of diapsids. |
At the beginning of meiosis, each primordial sex cell has paired homologous chromosomes, just like any other eukaryotic cell. |
Different from bivalent polyploids, multivalent polyploids pair their chromosomes among more than two homologous copies at meiosis. |
Vestigial structures are often homologous to structures that function normally in other species. |
Thus, poriferan spicules and chancelloriid sclerites do not appear homologous. |
Those similar genes from the mother and father will be located at the same spot on each homologous chromosome. |
