The neutral theory of molecular evolution proposed that most evolutionary changes are the result of the fixation of neutral mutations by genetic drift. Hence, in this model, most genetic changes in a population are the result of constant mutation pressure and genetic drift.
Answer:
This statement is true
Explanation:
Technologies associated with agriculture systems have greatly enhanced crop yields around the world. An example of this is the "Green revolution" in 1950-1960, where the combination of genetic improvement methodologies with the use of fertilizers was critical for the amazing increase in crop yields, particularly in new varieties of rice and wheat. Indeed, the agronomist who developed some of these high yielding varieties of wheat, Norman Borlaug, was awarded the Nobel Peace Prize for his contribution to the extensive increase in crop production, thereby helping to alleviate world hunger.

the man has a letter A in his blood group and the woman doesn't, instead she got an O
Answer:
Scientist obtain the primers from the DNA polymerases that preform the synthesis which must have an existing strand of nucleotides already in order to attach new DNA nucleotides. The existing strand of new DNA nucleotides is the primers
Explanation:
In order to happen DNA synthesis of a wanted portion of DNA in laboratory,
Scientist obtain the primers from the DNA polymerases that preform the synthesis which must have an existing strand of nucleotides already in order to attach new DNA nucleotides. The existing strand of new DNA nucleotides is the primer. To that existing strand of nucleotides we call primer. In a lab, scientists produce DNA primers through specific sequences that bind to other sequences of a single-thread DNA molecule and these are the primers commonly used to perform PCR.
