Plant sex chromosome evolution of dance in Savannah

Capture Hi-C promise to impact our understanding of gene interactions and expression networks of autosomal and sex-linked genes plant sex chromosome evolution of dance in Savannah], with implications for testing hypotheses of dosage compensation [ 11 — 13 ], and the role of sex chromosome—autosome interactions in adaptation and speciation [ 34 ].

Many animals and some plants have sex chromosomes. It was not until the early s that the sex chromosomes were first associated with sex determination. Chromosoma 15— We cannot exclude the possibility that the low ovule number observed may be a consequence of the smaller size of the flower meristem in males [ 29 ], and that the Y chromosome need not be solely responsible for it.

The Y chromosome in the liverwort Marchantia polymorpha has accumulated unique repeat sequences harboring a male-specific gene. Segregation types can also be determined if one has access to genotyping data from many at least 80 individuals, using a Bayesian method that ascertains the segregation type of a marker based on the inferred ploidy: autosomes are diploid in males and females, the X chromosome is diploid in females and haploid in males, the Y chromosome is specific to males and haploid and mitochondria are haploid in males and females fig.
