We review knowledge about the roles of sex chromosomes in vertebrate hybridization and
speciation, exploring a gradient of divergences with increasing reproductive isolation …

Triploids are rare in nature because of difficulties in meiotic and gametogenic processes,
especially in vertebrates. The Carassius complex of cyprinid teleosts contains sexual …

Parthenogenesis is asexual reproduction without any required participation from males and,
as such, is a null model for sexual reproduction. In a comparative context, we can expand …

Unisexual animals are commonly found in some polyploid species complexes, and most of
these species have had a long evolutionary history. However, their method for avoiding …

Unisexual reproduction is generally relevant to polyploidy, and unisexual vertebrates are
often considered an evolutionary “dead end” due to the accumulation of deleterious …

Obligate parthenogenesis evolved in reptiles convergently several times, mainly through
interspecific hybridization. The obligate parthenogenetic complexes typically include both …

Hybridization is a common evolutionary process with multiple possible outcomes. In
vertebrates, interspecific hybridization has repeatedly generated parthenogenetic hybrid …

The completion-of-tumor hypothesis involved in the dynamic interplay between the initiating
oncogenic event and progression is essential to better recognize the foundational …

Parthenogenetic species of Caucasian rock lizards of the genus Darevksia are important
evidence for reticulate evolution and speciation by hybridization in vertebrates. Female‐only …

Historical variations in climate and landscape configuration are the main aspects known to
generate and maintain diversity. Taxa associated with open habitats within broader forest …
