Answer:
Explanation:
In artificial selection, breeders select parent organisms with desired characteristics, in the hopes that when they are crossed, the desired variations will appear in the offspring. ... If the organism is "fit" it does survive and reproduce, thus possibly passing its traits to future generations.
The statement that would best describe the hypothesis that was created by Gregor Mendel in regards to the gametes would be that a gamete carries only one allele for a single gene. Hope this answer would be of big help.
The answer is B)<span> </span>temporal isolation.
<span>
<span>Temporal isolation is a type of reproductive isolation, which could be prezygotic or postzygotic. Temporal isolation is prezygotic reproductive isolation since it occurs before fertilization and zygote production. Temporal isolation is result of temporal differences in breeding. In this example, the breeding season of Rana aurora lasts from January to March while the breeding season of Rana boylii lasts from April to July. So, these two breeding seasons do not coincide and these species could not mate.</span></span>
