Answer:
Duchenne muscular dystrophy is a genetic disease caused by infection of the X-Chromosome. Males have only one copy of the X chromosome from their mother and one copy of the Y chromosome from their father. If their X chromosome has a DMD gene mutation, they will have Duchenne muscular dystrophy. Females have two copies of the X chromosomes. Since females have two copies of this gene, if one copy does not work, they have a second back up copy to produce the dystrophin protein. People with Duchenne muscular dystrophy do not make the dystrophin protein in their muscles. DMD affects the muscles, leading to muscle wasting that gets worse over time.
The two arteries that support the brain are the vertebrals and internal carotids. Hope this helps!

Answer:
DNA and fingerprint technology is said to be very accurate as it uses chemicals to separate strands of your own unique DNA to reveal the unique parts of your genome. which is your genetic make-up
This technology emerged in 1984 and invented by Professor Sir Alec Jeffreys who realized that you could detect variations in human DNA, in the form of these mini-satellites to produce a pattern unique to an individual
Human error still plays a role in terms of lab staff who make errors in conducting the DNA analysis, interpreting it or reporting the results of the analysis sometimes it occurs in entering the resulting DNA profile into a DNA database system which may result from a failure to comply a procedure, misjudgement, or some other mistake. There are protocols and precautions which can be introduced to minimise the opportunity for error during analysis or interpretation, however, the potential for human error cannot be fully eliminated.
Answer:
Meiosis is a special type of cell division in sexually-reproducing organisms used to produce the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome.
