Genetic diversity on the Z chromosome relative to the autosomes in three independent contrasts of shorebirds (least sandpipers vs. white-rumped sandpipers, western sandpipers vs. pectoral sandpipers, and red-necked phalaropes vs. Ruffs) was consistent with a reduced effective population size of males relative to females in polygynous species

During prophase I, the homologous chromosomes condense and become visible as the x shape we know, pair up to form a tetrad, and exchange genetic material by crossing over. In metaphase I, the tetrads line themselves up at the metaphase plate and homologous pairs orient themselves randomly.

Finally, genetic diversity may be higher in PARs than in regions that do not recombine in both sexes if recombination increases the local mutation rate (Perry and Ashworth 1999; Hellmann et al.

Kon et al. provide genome-wide evidence of evolution and diversity of goldfish. Three groups were identified based on domestication history. Six genetic loci associated with five goldfish phenotypes are described, showing that differential evolution of subgenomes in goldfish is likely to have contributed to the diversity of goldfish phenotypes.

a. Chromosomes are in unseparated, sister-chromatid form, at the end of the phase(s) _____. b. Sister chromatids separate during _____.
