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.

The varieties of chrysanthemums containing all multiples of nine chromosomes are autopolyploids. Their karyotypes share the feature of an even number of basic haploid chromosome sets.
Autopolyploids are described as the chromosome sets of an individual when more than two sets of chromosomes are present. They are specifically from the same specie. They can occur when pair of homologous chromosomes have not separated into different nuclei during meiosis. Since, during meiosis, the chromosome sets are separated equally thus karyotypes have an equal number of haploid chromosomes.
Organisms with 27 chromosomes are Triploids(3n) that are sterile because Trivalents at meiosis 1 would form a high number of unbalanced gametes to be formed.
