SNP reports of Cylindropuntia species from Dartseq used for population genetics analysis

Dioecy, the separation of sexes, is found in 6% of flowering plants. One widely known hypothesis suggests that it is an adaptation to mitigate inbreeding. A contrary hypothesis suggests that dioecy is an evolutionary dead-end. However, contrasting patterns emerged from population genetic studies that compared the genetic diversity between dioecy vs hermaphroditic species. Specifically, in Silene it was shown that dioecious species possess higher genetic diversity than hermaphroditic species, challenging the dead-end hypothesis. To evaluate whether dioecy is indeed advantageous, further studies are needed in systems with diverse sexual systems such as the genus Cylindropuntia (Cactaceae). It encompasses species with sexual separation observed solely in polyploids. Notably, these polyploids (C. wolfii and C. chuckwallensis) share similar ploidy, flower colors, and geographic proximity raising speculation about their shared ancestry. Moreover C. wolfii has been reported to have a low seed ..., , , # SNP reports of Cylindropuntia species from Dartseq used for population genetics analysis

## Description of the data and file structure

This dataset was generated using DArTseq, a reduced-representation sequencing method, to investigate genetic diversity and population structure in Cylindropuntia species. Fragments of cacti were collected from 251 individuals and SNPs were identified to assess genetic differentiation and population connectivity.

### Files and variables

File name: Report_DCylin23-8324_SNP_2.csv and Report_DCylin23-8324_SNP_3.csv\
File type: SNP

File description: SNP 2 Rows Format: Each allele scored in a binary fashion (\"1\"=Presence and \"0\"=Absence). Heterozygotes are therefore scored as 1/1 (presence for both alleles/both rows)

### Metadata columns in the file:

AlleleID - Unique identifier for the sequence in which the SNP marker occurs
AlleleSequence - In 1 row format: the sequ...,
