However, heterochromatin in condensed chromosomes can be stained differently from euchromatin after special procedures that typically utilize Giemsa stain. Fridolfsson AK, et al. However, this pattern did not hold in all tissue comparisons.

However, because the number of X chromosomes differs in males and females, there is a problem with the dosage of genes on the X chromosome. Although there is variation in the amount of polymorphism within each breed, the effect of reduced heterozygosity is not evident when gene-expression variation is compared across the breeds Table S4.

Important for this review, De Vries and colleagues have shown in FCG mice that the sexual dimorphic portrait of immunoreactive vasopressin in the lateral septum is also dependent on sex chromosome complement.

A somewhat higher rate of gene loss 8. During interphase, chromosomes are decondensed to form an apparently homogeneous mass of chromatin that consists of long DNA double helices associated with proteins.

  • Chromosomes are thread-like molecules that carry hereditary information for everything from height to eye color.
  • They consist of strands of DNA wrapped in a double helix around a core of proteins.

  • In humans, male sex cells or spermatozoa sperm cells , are relatively motile.
  • Do you know the sex of your cells? Not a question that is frequently heard around the lab bench, yet thanks to recent research is probably one that should be asked.

To identify whether the stickleback Y chromosome also contained genes shared with autosomes, but not the X chromosome, we first used the MAKER gene annotation pipeline [ 50 , 51 ] to assemble a complete set of coding regions across the Y chromosome reference sequence.
