Great photos! Leopard geckos never stop moving making them especially frustrating to photograph.

A project this big took a long time to complete, beginning 10 years ago. The broad outlines laid out over dinner while attending the 2016 World Congress of Herpetology in Tonglu, China

We made some other cool observations, including the evolution of partial dosage compensation and the patterns of gene loss and retention on the degenerating sex chromosomes (the Y or the W). Give it a read if you are interested.
Time-calibrated gecko phylogeny on the left, with the silhouette of a gecko overlaid onto it highlighting the constrained pathways of sex chromosome evolution. Most gecko sex chromosomes originated independently from different ancestral chromosomes. Five of 11 datable origins coincide near the MMCT [~10 million years ago (Mya)]. Regions ancestrally enriched in TPEGs tend to evolve into ZW systems, whereas regions depleted of such genes tend to evolve into XY—a pattern observed across multiple independent amniote sex chromosome origins.

While any chromosome seems to be able to act as a sex chromosome, ancestral gene content is correlated with the direction of evolution – XY vs ZX – with testis-enriched regions tending to evolve into ZW systems & testis-depleted regions into XY.
Gecko sex chromosomes divergence and evolution. Phylogeny of sampled gecko species and their sex chromsome system. Boxplots show the proportion of testis (left) and ovary (right) preferentially expressed genes on the oldest region of the X/Z-SDR of each gecko compared to the proportion of gonad-bias genes from genomic background. Red dots in the boxplot indicate the difference of the studied gecko while the other black dots indicate the ancestral states indicative by the difference in the other geckos. Any deviation is shown as the background color in each boxplot: red, significantly higher than genomic background in geckos; blue, significantly lower; white, no significant difference.

We asked whether some chromosomes were better at being sex chromosomes than others. We inferred an ancestral gecko karyotype of 19 chromosome pairs and 17(!) of them have become sex chromosomes, confirming independence of sex chromosome recruitment in different species.
Homologous gecko ancestral chromosomes (GAC) detected in the sex chromosomes of all studied geckos (phylogeny on left). Boxes and arrows are color-coded by GAC. A diagonal line is drawn in the box when the GAC is homologous only to PAR. The parentheses under the GAC at the top indicate the number of times each GAC became sex chromosome, where the color indicates whether the GAC evolved into SDR in geckos (black: evolved into SDR, gray: evolved into PAR only).

In other words, the evolution of a new sex chromosome system includes not just the evolutionary option of an XY or ZW system but also the option that any one of the chromosomes in the genome could be recruited into this sex-determining role.

We confirmed previous research that sex chromosomes have evolved repeatedly in geckos. However, our genome-scale data let us move beyond just XY vs ZW. We observed different chromosomes in the genome acting as sex chromosomes in different species.
Whole genome alignment across the 22 geckos covered in this study. Alignments are color-coded based on gecko ancestral chromosomes (GACs; noted at top). For each sex chromosome, the PARs and stratum are highlighted with different colors. The inferred fusion and other rearrangement events associated with the sex chromosomes are shown on the tree.

Combining our new genome assemblies with existing genomes we were able to uncover some incredible details about gecko genome biology and sex chromosome evolution.

We generated chromosome-level genomes from 19 gecko species, including representatives from all 7 gecko families. These species have diverse sex-determining systems, including both XY and ZW sex chromosomes and temperature-dependent sex determination (TSD).
Gecko genome assemblies, phylogeny, and sex-linked sequence dataset. Genomic phylogeny of gecko with divergence times as branch lengths. Species name color: red, generated in this study, black, published. The sex determination systems (SDS) are also shown at the leaf node: blue, XY; orange, ZW; grey, TSD.

I'll have you know we actually used FOUR gecko species in the paper! 🤣 but... a skink also makes an appearance! 🧪
A two panel figure from a scientific paper. The left panel consists of haplotype-specific k-mers plotted against sequence length for the the Christmas Island skink (Cryptoblepharus egeriae) - a skink silhouette is at the bottom of that panel. The right panel corresponds to an alignment of the putative sex chromosome haplotypes for the same species.

There are several gecko species native to Crete and they have different sex-determining systems. The Common Wall Gecko (Tarentola mauritanica) has TSD. The Mediterranean House Gecko (Hemidactylus turcicus) has XX/XY sex chromosomes. We found both at the conference hotel! 🧪🦎 @biol-vsd.bsky.social
