Answer:
To put it simply, the amount of radiation from one adult chest x-ray (0.1 mSv) is about the same as 10 days of natural background radiation that we are all exposed to as part of our daily living.

Should I Become a Genetic Counselor?
Genetic counselors help educate people about their chances of inheriting genetic disorders or diseases using information from a patient's family medical history. They explain possible testing options and provide support to patients and family members. They also might educate other healthcare professionals, students, and the public about genetic disorders. Sharing potentially upsetting results with clients can be stressful.

Steps to Become a Genetic Counselor
Step 1: Earn a Bachelor's Degree
A bachelor's degree in biology or a healthcare-related field typically is a requirement for enrolling in a genetic counseling master's degree program. These programs provide students with the science and math knowledge needed for a career in genetic counseling. Coursework focused in genetics, biochemistry, and statistics is valuable to future genetic counselors.
Some schools offer internships or summer programs for students interested in genetic counseling. These programs provide students with a chance to gain experience at clinics or hospitals and prepare them for a graduate degree program. Also consider doing volunteer work or providing counseling. Performing work for a crisis hotline or reproductive counseling service can help provide the skills and qualifications needed for a graduate program in genetic counseling.
Step 2: Earn a Master's Degree
A master's degree in genetic counseling usually is required for genetic counselor positions. These programs typically provide coursework in human genetics, lab work, counseling, and research. Students develop the skills needed to research, counsel, and consult with patients, their families, and members of the healthcare community to provide information on genetic conditions. Admission requirements usually include a bachelor's degree with credits in genetics, biochemistry, and statistics. Some schools require applicants to have performed some type of counseling work.
Step 3: Get Certified/Licensed
The American Board of Genetic Counselors (ABGC) offers a certification program. This certification is technically voluntary; however, some states require it for licensing, and some employers prefer it. In addition, some states require genetic counselors to become licensed before performing work with the public. Certification requirements include completion of a graduate degree program in genetic counseling through an ABGC-accredited program and passage of a written exam. ABGC certification can serve as proof of competency and give job candidates an edge in employment.
Step 4: Gain Work Experience
Entry-level positions allow genetic counselors to work under supervision, assessing patients, and providing counseling. More advanced positions allow genetic counselors to work independently at these duties, in addition to performing research and providing education to the public and healthcare professionals. The National Society of Genetic Counselors (NSGC) provides individuals with online education resources and opportunities to network with other members of the field. Courses go over self-marketing, mentoring, and instructional guides on starting a clinic.
Genetic Counselors need a field-specific master's degree, and certification and state licensure might be required.
I) Locus- the chromosomal site where a specific gene is located. A locus is a fixed position on a chromosome, like the position of a gene or a marker. Each chromosome carries ,many genes; human's estimated haploid (n) protein coding genes are about 20,000, on the 23 different chromosomes.
ii) Interference; the observed double crossover frequency differs from the expected double crossover frequency. Cross over interference is used to refer to the non-random placement of crossovers with respect to each other during meiosis. It results in widely spaced crossovers along chromosomes. Interference may exert its effect across whole chromosomes. As chromosomes in many eukaryotes are large, interference must be able to act over megabase lengths of DNA.
iii) Linkage- the tendency for genes located in close proximity on the same chromosome to be inherited together. Normally when two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.
iv) Recombination- the process by which a new pattern of alleles on a chromosome is generated. Genetic recombination is the production of offspring with combinations f traits that differ from those found in either parent. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes.
