11. Therefore, Y-autosome interactions are ruled out in this type of hybrid sterility. 12. Aneuploidy of autosomes is not well tolerated and usually results in miscarriage of the developing fetus. 13. Sciara basically has 4 pairs of chromosomes 3 pairs of autosomes and one pair of allosomes. 14. In Haplodiploidy, males receive one half of the chromosomes that female receive, including autosomes . 15. The quantity and distribution of heterochromatin among both X chromosomes and autosomes is different as well. 16. Ainsworth describes sex determination in the genus as using " an X / autosome dosage type ". 17. The first 22 pairs are called autosomes which look exactly the same in both males and females. 18. "C . elegans " has five pairs of autosomes and one pair of sex chromosomes. 19. Specifically, in the DNA of a typical human, have all 22 autosome pairs have been recombinated? 20. In 1999, the entire DNA sequence of human chromosome 22, the shortest human autosome , was published.
