Keep it in an aerobic environment, meaning that there should be oxygen present. Fermentation is anaerobic, hence aerobic conditions will prevent fermentation from occurring.
Purpose:Extraction and successful PCR amplification of DNA from humanremains in historical and forensic cases have great importance. The purpose of this study is to demonstrate the efficiency of a method of DNA extraction and PCR amplification of embalmed dried human cadaveric skeletal fragments and teeth specimens from Sokoto, Northwestern Nigeria.
Materials and Methods: The efficiency of a method of DNA extraction and PCR amplification was tested on thirteen (13) embalmed dried human cadaveric skeletal fragments and nine (9) teeth specimens from Sokoto, Northwestern Nigeria were used in the study.
Results: Of the 13 embalmed dried human cadaveric skeletal fragments, 12 (92.3%) samples amplified with apparent bands. For the 9 embalmed dried human teeth specimens, 7 (78%) samples amplified with apparent bands.
<span>Conclusion: The study has shown that our method of DNA extraction and PCR amplification was efficient on embalmed dried human cadaveric skeletal fragments and teeth specimens, from Sokoto, Northwestern Nigeria.</span>
Answer:
It is homozygous at two gene loci.
Explanation:
An organism may be homozygous or heterozygous for a particular gene. The presence of two identical alleles of a gene in the genome of an organism makes it homozygous for the gene. On the other hand, the presence of two dissimilar alleles of a gene makes the organism heterozygous for the gene.
For instance, AA or aa are homozygous states since two copies of identical alleles (dominant and recessive respectively) are present. The genotype "Aa" is heterozygous since it has one dominant and one recessive allele for a particular gene.
The given genotype "AABbcc" is homozygous for "A" and "c" due to the presence of two copies of dominant and recessive alleles respectively. However, it is heterozygous for the second loci (Bb). Since the recessive allele is present in the homozygous state (cc), it will express itself.
