Natural hybridization between two sibling species of Anolis lizards: chromosome cytology |
|
| Authors: | G C Gorman L Atkins |
| Abstract: | The Lesser Antillean lizards Anolis trinitatis and Anolis aenous were both apparently introduced to Trinidad where they are hybridizing. The parental species have 36 and 34 chromosomes, respectively. Hybrids have 35 chromosomes. Meiosis in hybrids is abnormal. There is an accumulation of cells at metaphase I, and poor homolog pairing, characterized by a low frequency of chiasmata and numerous univalents. |
