Genome Size Evolution in New Zealand Triplefin Fishes

Article Abstract:

Research on New Zealand triplefins is presented. Genome size was found to be significantly plastic, with a size difference of 50% between the largest and the smallest genomes and variation of up to 20% occurring within genera. Genome size does not appear to be linked to neoteny, longevity, or morphological complexity as in other organisms.

Retention of Latent Centromeres in the Mammalian Genome

Article Abstract:

The article examines hypotheses that may explain centromere location permutability within a mammalian chromosome, incorporating the commonness of centromere repositioning in karyotypic evolution. Human studies and the tammar wallaby are used to assess these hypotheses.

Genome Sizes in Afrotheria, Xenarthra, Euarchontoglires, and Laurasiatheria

Article Abstract:

The article presents genome size measurements for 12 house-mouse species and 15 armadillo species in a comprehensive data set. Discussion focuses on repetitive elements and their role in adaptation.
