William and Quentin are fraternal twins. This means they share, on average, what % of genes with one another?
nordsb [41]

Answer:

The correct answer is 50%

Explanation:

Fraternal twins are the twins which are produced from the fertilization of two different eggs by two different sperms. These eggs are released at the same time.

So as fraternal twins are produced from fertilization of two different eggs therefore they share 50% of genes with each other just like other siblings. They are also called dizygotic twins

Identical twins are produce from a sigle fertilized cell which later divides into two cell mass. Indentical twins share 100% gene. Therefore the correct answer is 50%.

The molecular clock has limited usefulness for estimating divergence times among species in part due to the saturation of DNA se
Greeley [361]

<u>Answer:</u>

<em>In highly diverged lineages, the substitutions process will occur at sites that have been substituted previously</em>.

<u>Explanation:</u>

Molecular clock uses the mutation rate to reduce the time in prehistory when the life forms are diverged. <em>The molecular clock uses the sequence of amino acids and nucleotide sequence for the DNA.</em>  

This clock does not measure any time but the number of mutations, and other changes over certain time.  <em>Sometimes its useful property might be limited due to the highly diverged lineages.</em>
