Suppose a geneticist isolates two bacteriophage mutants. One mutation causes clear plaques (c), and the other produces minute pl
Nesterboy [21]

Answer:

The mentioned parental types are c+m- and c-m+. Thus, the recombinants will be c+m+ and c-m-.  

Now, the given distance between c and m is 8 map units. Thus, the recombinant frequency is 8% or 0.08.  

The total recombinants from 1000 plaques will come out to be 80,  

Thus, the recombinants of each type will be 40.  

Total parental type will be 920, and therefore, each parental type count will be 460.  

Thus, expected c+m- = 460, expected c-m+ = 460, expected c+m+ = 40 and expected c-m- = 40.

<h3>How are fossils dated?</h3>

The process of dating fossils is done by analyzing the sedimentary rocks that are formed around the animal for thousands of years, an analysis is also made of the atoms of the fossil of the animal, to give a certain accuracy to the research data.

With this information, we can conclude that Luke can use this information to sort the photos into four batches excluding the time period when it is not possible for all participants to be in the photo.
