Imagine two closely related, but separate, species of fish reproduce and the hybrids offspring have higher fitness than either o
f the parent species. Given enough time, the most likely outcome will be: Group of answer choices The two original species will eventually fuse into a third new species, and disappear. The two original species will remain, and a third new species will appear. Nothing: the two original species will remain, and the hybrids will eventually disappear.
The two original species will eventually fuse into a third new species, and disappear.
Explanation:
According to Darwin's theory of evolution, species that are better adapted to their environment have greater chances of surviving long enough to reproduce and pass on these favourable characteristics to their offspring. This is known as 'survival of the fittest'.
The original species lack the resilience of the new hybrid species hence the two original species will eventually disappear and fuse into the third specie.
No; only a small percentage of variants cause genetic disorders—most have no impact on health or development. For example, some variants alter a gene's DNA sequence but do not change the function of the protein made from the gene.
