During sexual reproduction, traits from both parents of an organism combine to form a new set of traits. For a given set of selection pressures in the surroundings of a population, the combinations of genes dictate whether the organism has favorable or non-favorable traits. Thus, natural selection is dependent on reproduction.
Answer:
The correct answer will be option-Crossover region
Explanation:
Recombination is a complex process which leads to the exchange of the genetic material between sister chromatids.
The recombination process is mediated by the recombinase enzyme which recognize the specific sites and allows the formation of the protein-DNA complex called synaptic complex.
The synaptic complex contains the short asymmetric sequence called the crossover region, which represents the rejoining and the DNA cleavage site.
Since crossover region represents the recognition sequence which is flanked is known as the crossover region.
Thus, the crossover region is the correct answer.
Freshwater, ocean water, and terristrial.
There are three broad categories of ecosystems based on their general environment, as those that were mentioned above. Within these broad categories are individual ecosystem types based on the organisms present and the type of environmental habitat.
Answer:
The first blood transfusion in which the donor blood type is A+ and recipient blood type is A- would not be successful as the donor blood is A+, which signifies that the blood comprises both Rh factor and antigen A, while the recipient blood group is A-, which signifies that the blood does not comprise Rh factor and possess only antigen A. Therefore, at the time of transfusion, the Rh factor of donor blood will be regarded as a foreign body by the recipient, and thus, will generate antibody against the donor Rh factor provoking immune rejection and agglutination.
On the other hand, the second blood transfusion in which the donor blood type is O- and the recipient blood type is AB+, the blood transfusion would be successful as the blood group O- is a universal donor, as it neither possesses any A or B antigen nor Rh factor. This blood group is accepted by all the blood group recipients.
