Homozygotes for one allele are favored over all others.
Antigen challenge and clonal selection are most likely to occur in the secondary lymphoid organs, such as the lymph nodes and spleen. These organs are where antigens encounter immune cells, triggering an immune response and the selection of specific immune cell clones.
directional selection and disruptive selection both decrease genetic variation - apex
Darwin's most important idea was the theory of natural selection, which proposed that organisms that are better adapted to their environment are more likely to survive and reproduce. This concept is at the core of his theory of evolution by natural selection.
Disruptive selection is most likely to produce an African butterfly species with two strikingly different color patterns in the wild. In disruptive selection, individuals with extreme phenotypes are favored, leading to the maintenance of distinct color patterns in a population. This can be advantageous for butterfly species to better blend in with their environment or attract mates, enhancing their survival and reproductive success.

Homoygotes for one allele are favored over all others.
Homoygotes for one allele are favored over all others.
Aside from decreasing genetic variation they both are not normal Gaussian curves. Disruptive selection has two normal curves at either end of the distribution. Directed selection has an abnormal curve with most of the data distributed is a skewed manner from the mean of distribution.

Aspirin is the NSAID that is most likely to cause ulcers.
A convenience survey or a self-selection survey is most likely to be affected by bias
Some are directional like the eagle F1, however most are not directional.
When the largest organisms are most fit, it shows a pattern of directional selection, where individuals at one extreme of a trait distribution have higher fitness. This can lead to a shift in the trait distribution over time, favoring the larger size.
Carelessness and inattention is most likely the cause of someone to fall overboard.
The eccentric muscle contraction is most likely to cause discomfort in q5.
