It is produced by transformed bacteria.
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:
The genes are linked, and the arrangement is coupled (one homolog has both dominant alleles; the other homolog has both recessive alleles).
RY
/
ry
Explanation:
R_= colored aleurone
rr= colorless aeurone
Y_= green plant
yy= yellow plant
They do a testcross between a plant of unknown genotype and phenotype and a plant that is homozygous recessive for both traits (yr/yr) the following F1 is obtained:
- 88 Colored, green (RY/ry)
- 92 colorless, yellow (ry/ry)
- 8 colorless, green (rY/ry)
- 12 colored, yellow (Ry/ry)
If the genes assorted independently, all of the possible offspring phenotypes would appear in the same frequency. However, they obtained 2 phenotypes much more abundant that the other two. Since recombination is a rare event during crossing over, when two genes are linked the recombinant gametes are produced less frequently than the parentals.
We can propose that the phenotypes Colored, green (RY) and colorless yellow (ry) are the parental gametes, and the unknown plant has the arrangement RY/ry, with both genes linked.
