<span>Molecular clock is a scale which uses a technique whereby evolutionary time for different life forms is deduced from the mutation rate of biomolecules. Biomolecular data used for calculations in order to come up with the prehistoric time scale normally uses nucleotide sequences for DNA or amino acid sequences for proteins.
Hence, in order to develop a molecular clock, one would need: a sequence of molecules, the rate at which changes occur in a type of molecule and how much total change has occurred in a type of molecule from different species.</span>
Answer: Option B) Yes, the solution is hypotonic, causing the cell to burst.
Explanation:
Because a hypotonic solution is of lower concentration to its surrounding, a cell placed in such solution absorbs the content of the solution, swells and then burst due to the uncontrolled inflow of the solution through its cell membrane.
Thus, the answer is Yes, the solution is hypotonic and cause the cell to burst.
Answer:
Incomplete Penetrance. Some genes are incompletely penetrant.
Sex-limited genes are ones that are inherited by both men and women but are normally only expressed in the phenotype of one of them. The heavy male beard is an example.
Pleiotropy. A single gene may be responsible for a variety of traits.
Stuttering Alleles.
