Answer:
No, not all genetic change is adaptive.
Explanation:
This is because genetic changes happen in many ways and this can be adaptive or not.
The main form of genetic change happens through genetic mutations, and these mutations are not always adaptive.
One might think, for example, of a river polluted with a chemical reagent that causes mutations in the scale genes of the local fish population, mildly damaging the way they swim. Despite being a nonadaptive genetic change of fish, they have continued to reproduce so that this change is part of their population.
Although this happens, it is important to note that this rarely happens. Since natural selection ends up selecting the most suitable in the long run.
Answer:
This is 25%
Explanation:
Analysis, Since the dominant brown eyed parents produce blue eye child, this shows they are heterozygote dominant
However,this fraternal twin is not genetically identical, due to the blue eye color,(recessive) but the fact remain that they are the parents.(because he inherited the recessive allele from each of the parent)Therefore the probability is 25%.
This is because he is the only one out of the 4 kids( based on Mendelian fashion) this is 1/4,25%
