1. Asexual reproduction does not have genetic diversity. With sexual reproduction, this has been a man advantage since mixing a gene pool can produce diversity.
2. There is less variation produced with the offspring. The organism becomes less adapted to certain environmental changes. The entire communities of the genetically identical organisms might not survive such changes.
3. Asexual reproduction usually leads to struggle for existence as well as overcrowding.
The main distinction of asexual reproduction from sexual reproduction is that there is no need for two parents as well as special cells to reproduce. It means that special mechanisms have been essential to combine sex cells and allow fertilization are no longer required. This form of reproduction process has been simply mitosis. This results to copying of a parent organism. Most of the time, plants are thought to undergo reproduction. However, you have to know that there are also several kinds of animals that can reproduce asexually. By simply learning about the advantages and disadvantages of asexual reproduction, it will be easier for you to take care of other organisms around you.
True! Hydrogen bonds hold two stands of DNA together by forming nitrogenous bases. <span>A (adenine) can </span>form hydrogen bonds<span> only with T (thymine)</span>
Because artificial selection is the one made by humans like dog breeds.
Disruptive selection is when extreme values for a trait in a population are favored like big and small sizes. Stabilizing is when the trait is pushed towards the average. Sexual selection is when the trait aids in competition among individuals for access to preferred mates.
I believe it is D. the genetic variations are in the phenotype of the organism. The reason why I say this is because the phenotype is the physically noticeable characteristics in an organism, this allows them to mutate differently and only the ones who are fit enough and have the best phenotypes will survive.
