Answer:
0 mya, 175mya, 250mya, 400mya
Explanation:
The substance which highest million year ago should be more in-depth in the soil hence 400mpa should occupy the highest depth below the ground.
Answer: Option A
Explanation:
In Prokaryotes the the rate of new mutations is much more as compared to the eukaryotes. The rate of accumulation of mutation is slow in case of eukaryote because their generation is long as compared to prokaryotes.
Prokaryotes have short generation time and large population size which enables them to accumulate the mutation quickly.
The machinery is also not that complex when it comes to prokaryotes. Transduction, conjugation and tranposable elements. So, the changes during these processes leads to mutation in the prokaryotes and can be observed quickly due to their small generation.
Answer:
B. As the distance between loci increases, some multiple crossovers go undetected such that the relationship between recombination frequency and map distance ceases to be linear.
Explanation:
When calculating recombination frequencies, and hence, map distances, we might notice that these distances are not completely additive. They might vary. <em>For example, let us say that we have three genes, A, B, and C, in that order. </em>We calculated that the <em>distance between A and B equals 5.9</em> MU and that <em>B and C are 19.5 MU apart.</em> According to this, we might say that the <em>total distance between A and C is 25.4 MU (5.9 + 19.5). </em>However, after a<em> two-point calculation between A and C, the value equals 23.7 MU. </em>
The recombination frequency between these two genes located in the extremes and far apart underestimate the actual genetic distances between them because there might occur other crossing-overs that were not detected. This is <em>when calculating the distance between A and C, we probably will not detect the occurrence of a double recombinant between them, and hence, we might sub-estimate the real distance.</em>
The relationship between the actual map distance (number of crossing overs) and the recombination frequency between two loci, is not lineal. The farther apart are the two genes, the worse is the distance estimation.
