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.

<h2><u>Answer:</u></h2>

Amid the Ordovician Period, the outside of the earth was drastically unique in relation to it is today. About all life on earth was in the seas.

The Ordovician Period started with a noteworthy eradication called the Cambrian– Ordovician annihilation occasion, about 485.4 Mya (million years prior). It went on for around 42 million years and finished with the Ordovician– Silurian elimination occasions, about 443.8 Mya (ICS, 2004) which cleared out 60% of marine genera.  

The timeframe that occurred 488 to 443 million years back. Amid the Ordovician time frame, some portion of the Paleozoic time, a rich assortment of marine life thrived in the tremendous oceans and the primary crude plants started to show up ashore—before the second biggest mass annihilation ever finished the period.
