Answer:
The visible DNA fingerprint can help extract DNA which, after analysis, can accurately identify the suspect or perpetrator of the crime.
Explanation:
DNA Fingerprinting:
- DNA fingerprinting is a molecular analysis tool that can help identify a suspect in a crime through DNA extracted from fingerprints.
- Specific patterns in the DNA, known as polymorphisms, can be identified through DNA fingerprinting.
- The DNA fingerprinting process involves:
- Extraction and purification of the DNA from the fingerprint.
- PCR amplification to obtain high yield.
- Fragmentation of the DNA by use of restriction enzymes.
- Gel electrophoresis analysis of the fragmented DNA.
- Analysis of gel to compare the size of the bands.
Answer:
2 out of 4
Explanation:
Let the allele for cleft chin be represented by A, while the alternate recessive version would be a.
A parent that is heterozygous for cleft chin would have the genotype Aa.
A parent without cleft chin would have the genotype aa.
Aa x aa
Aa Aa aa aa
Aa - cleft chinned = 2/4
aa - normal chin = 2/4
Thus, two out of every four (2/4) of their offspring would have cleft chin.
<span>The ritual of strolling leisurely around a walkway is called a promenade. Did you know that the event known as high school prom originated from this custom of promenading? The word prom is derived from the word promenade. During a prom, people dress up and display themselves socially, just as people do when they go to a plaza in the Spanish-speaking world.

The answer is c. Natural selection is when inheritable traits that they need to survive is passed down to the next generation. Biological revolution changes the environment so the organism's offspring has to change with it through genetic variations. If you increase it's life span than you may not have genetic variation over a period of time.
