Answer: The correct answer for the blank is -
1.) A. Phenotype
B. Genotype
Phenotype corresponds to the physical appearance of a particular characteristic or morphological form in an individual.
Example - Hair color, plant height, skin color.
On the other hand, genotype corresponds to the genetic makeup of an individual. It is depicted by the gene that is present in the individual organism. Example- Genotype for dwarf height in pea plant is 'tt', which carries both recessive gene variants.
Thus, we can physically see the phenotype of a trait, but not the genotype.
Answer:
True (although question is not clear enough)
Explanation:
Adaptive radiation occurs when <u>organisms evolve from the same ancestor. This process takes place as a result of environmental changes or when they are introduced to or colonize a new environment.</u> These changes become challenges that force these individuals to adapt to these new conditions.
Therefore, <u>this results into a faster evolution that creates different new forms</u> that possess a diversity of variations adapted to their new feeding habits, environment, and behavioral needs.
<em>One of the most famous examples of adaptive radiation is the formation of new forms of Galapagos finches.</em> These striking finches, which arose from a common ancestor, evolved different beak sizes and shapes that were especially adapted to different types of food. As different as they may appear, they are closely related!
