Is an all-female population possible?

If you’re a reptile, it most certainly is.

The Desert Grassland Whiptail lizard (Aspidoscelis uniparens) is an all-female species. These reptiles reproduce by parthenogenesis; eggs undergo a chromosome doubling after meiosis and develop into lizards without ever being fertilized.

Interestingly enough, ovulation is enhanced by female-female courtship and “mating” (pseudocopulation) rituals that resemble the behavior of other lizard species that reproduce sexually.

These happy lesbian lizards live in dry deserts from central Arizona to west Texas and south into Mexico.

Meanwhile, in the United States, the struggle for gay rights continues.  Amy Weber, a married lesbian mother of two, gives an inspired statement to Troy, Michigan Mayor Janice Daniels, who recently made anti-gay remarks on Facebook.
