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.

Polar ice cap

Explanation:

The polar ice cap is an area on the earth that extends from 66.5° north and south of the equator to the poles.

The polar ice cap is an area of very low temperature and the surface is mostly covered by ice.

  • The vast polar ice caps the earth's northern and southern limits.
  • This is the region of the Arctic and Antarctic circle.
  • This region receives diffused solar radiation from the sun.
  • This is why they rarely warm up.
  • The region of the equator has no ice because they receive direct sunlight.
  • The soil here is frozen.
