The Ratio of X Chromosome to Autosomes02:45

The Ratio of X Chromosome to Autosomes

10.0K
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.  
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...

Dosage Compensation

In animals, gender is determined by the number and type of sex chromosome. For example, human females have two X chromosomes, and males have one X and one Y chromosome, whereas C.elegans with one X chromosome is a male, and the one with two X chromosomes is a hermaphrodite.
In addition to sexual development, the X chromosome has genes involved in autosomal functions such as brain development and the immune system. Therefore, males and females with  distinct numbers of X chromosomes will...

Inheritance of Chromatin Structures

7.8K
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

Area of Science:

  • Developmental Biology
  • Evolutionary Biology
  • Genetics

Background:

  • Runx genes are highly conserved across metazoans, playing vital roles in development.
  • Studying simpler organisms provides valuable insights into complex Runx gene functions.
  • Functional redundancy in vertebrate Runx genes necessitates simpler models for detailed analysis.

Purpose of the Study:

  • To review the role of Runx genes in invertebrate model organisms.
  • To highlight conserved Runx functions across different phyla.
  • To explore evolutionary insights derived from comparative Runx studies.

Main Methods:

  • Comparative analysis of Runx gene sequences and functions.
  • Focus on Runx genes in diploblasts (sea anemones, sponges) and lower triploblasts (sea urchin, nematode, planaria, insect).
  • Utilizing model organisms like C. elegans with a single Runx gene.

Main Results:

  • Runx genes are present in a wide range of invertebrates, including diploblasts and lower triploblasts.
  • Functional conservation of Runx genes is observed across diverse phyla.
  • Recent findings indicate Runx gene presence in protists, expanding their known evolutionary range.

Conclusions:

  • Invertebrate model organisms are invaluable for understanding fundamental Runx gene biology and function.
  • Comparative studies of Runx genes yield significant evolutionary insights.
  • Unifying themes in Runx function during development and regeneration are emerging from invertebrate research.
