Question

A group of scientists determines that a mitochondrial DNA sequence shared by two species has a constant mutation rate. The sequences of mitochondrial DNA for the two species are shown below.

Species A: GACTGGGCATTA
Species B: GACCGGACATGA

Using the principles of molecular clocks and a known mutation rate for this sequence, the scientists determine that these species diverged from a common ancestor 30 million years ago. Based on this information, how much longer do you predict it would take these species to differ by a total of seven base pairs?

Answer 1

60 million years

20 million years

140 million years

80 million years

Answer 2

60

Answer 3

Could you explain this to me? Thank you. :)

Answer 4

the first DNA is 30 million year right to find the second one it take 60 million years

Answer 5

Thanks! What about this one:
How are the results of genetic drift similar to the results of gene flow?

Both result in a loss of individuals from the affected population.

Both result in an increased rate of mutation within the population.

Both result in a change in allele frequencies in the affected population.

Both result in a loss of genetic diversity in large populations.

Answer 6

u didnt give medala

Answer 7

thanks

Answer 8

No problem. What about the second question?

Answer 9

where is my medalia

Answer 10

The answer turned out to be incorrect. Sorry.
