The most likely explanation of as to why there is a high
proportion of winged individuals in a population of bean aphid was because
there is a presence of high population density or another reason is that there
is already a high population if before the aphids develop or has developed.
Answer:
The correct answer will be option-A.
Explanation:
Recombination is a process in which the DNA sequences get exchanged between two homologous chromosomes. It occurs during gamete formation and is the basis of genetic diversity.
The process requires many enzymes, the key enzyme of which is Recobinase A or RecA protein which catalyzes the homologous recombination using ATP as an energy molecule.
RecA binds to the single-stranded DNA at the break site and forms pre-synaptic structure. Thus, it initiates the reaction of strand exchange and is the correct answer.
