Abstract:
Haplotype frequencies for 11 Y-chromosomal short tandem repeats (STRs) included in the PowerPlex Y Systems (Promega) were determined in a sample of 275 unrelated healthy male individuals of Chinese Manchu ethnic group living in Liaoning (northeast of China). A total of 238 haplotypes were identified, of which 215 were unique, 14 were found in two individuals, 6 were shared in three individuals, 1 was shared in four individuals, and 2 were shared in five individuals. The observed haplotype diversity value and discrimination capacity were 0.9985 and 0.8654, respectively.

Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size. Today,...
X and Y Chromosomes
The germline cells such as egg and sperm cells carry only half the number of chromosomes, i.e., 22 autosomes and one sex chromosome. All eggs have an X chromosome, while sperm cells can carry an X or...
