Both parents' genotypes are Bb (brown blue)
the punnet square would be
BB(kid one) Bb(kid two) Bb(kid three) bb(kid four)
kid one will be homozygous for brown eyes. kid two and three will be heterozygous for brown eyes. kid four will be homozygous for blue eyes
in other words, 75% will have brown eyes. 25% will have blue eyes
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.
