Hypertensionor high blood pressure, appears to be Y-linked in the hypertensive rat. The extra genetic material in these cases can lead to skeletal abnormalities, decreased IQ, and delayed development, but the features of these conditions are variable.
In females, the effect of the mutation may be masked by the second healthy copy of the X chromosome. Many genes are unique to the Y chromosome, but genes in areas known as pseudoautosomal regions are present on both sex chromosomes. Geneticists use diagrams called idiograms as a standard representation for chromosomes.
Protein structure prediction for the male-specific region of the human Y chromosome.
Categories : Genetics. Am J Med Sci. The sex chromosomes form one of the 23 pairs of human chromosomes in each cell. Epub Feb Ann Med. Hum Genet. It is a form of sex linkage.
European Journal of Human Genetics. Retrieved The extra genetic material in these cases can lead to skeletal abnormalities, decreased IQ, and delayed development, but the features of these conditions are variable. Unsourced material may be challenged and removed. Extra copies of genes from the pseudoautosomal region of the extra X and Y chromosomes contribute to the signs and symptoms of 48,XXYY syndrome; however, the specific genes have not been identified.
In general, traits that exist on the Y chromosome are Y-linked because they only occur on that chromosome and do not change in recombination. Males with 47,XYY syndrome have one X chromosome and two Y chromosomes in each cell, for a total of 47 chromosomes.
Epub Feb Stern detailed in his paper genes he suspected to be y-linked. Idiograms show a chromosome's relative size and its banding pattern, which is the characteristic pattern of dark and light bands that appears when a chromosome is stained with a chemical solution and then viewed under a microscope.
