11. Other results point to the hypothesis of sex-linked genes , or, inheritance through the maternal chromosome. 12. That is, females carrying a sex-linked gene of dwarfism are always pure and exhibit the trait. 13. Here, a complex of proteins bind to the X-linked genes to effectively double their genetic activity. 14. Most of the phenotypical variation among breeds can be explained by the sex-linked gene " K ". 15. This mainly occurs with sex-linked genes ( i . e ., those on the sex chromosomes ). 16. The bead-linked genes are then rendered single-stranded so that each is ready to bind with its counterpart. 17. Histone acetylation and the consequent upregulation of X-linked genes in males is dictated by the MSL complex. 18. However, it is important to note that recombination frequency tends to underestimate the distance between two linked genes . 19. The current estimate of sequenced X-linked genes is 499 and the total including vaguely defined traits is 983. 20. In rare occasions, a dominant form of the X-linked gene mutation will affect both males and females equally.
