Χ Chromosome Analysis (Χ-STR)

This test strengthens the results of biological relationship testing

Description

Males have one X chromosome which they transmit as such to all female offspring. This means that sisters with common biological father will share one identical x chromosome.

Females have two X chromosomes, each of which can be transmitted to both male and female offspring. Due to genetic recombination phenomena that appear between these 2 chromosomes in females, information transmitted from the mother to her offspring may be slightly or largely different.

The use of specialized analysis software which takes into account the basic principles of X chromosome inheritance mentioned above makes X-STR analysis suitable as a complementary tool to basic analyses of biological relationship in order to strengthen the results.

Analysis of 12 X chromosome genetic markers (STRs)

DNAlogy analyses include the study of 12 X chromosome genetic markers (STRs) to ascertain the biological relationship.

Results

The results of laboratory analyses are entered in special software which taking into consideration all necessary parameters process the data to compute the final results.

Expert Report

Analysis and interpretation of results is carried out by 2 special experts in our laboratory, who also sign off the final expert report that contains the laboratory results and the detailed conclusions.

The results of analyses are notified only to the person that submitted the request in 5-7 working days, or 2-3 working days (Express procedure).
