Unlike natural selection, genetic drift does not depend on an allele’s beneficial or harmful effects. Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are sampled to produce the next generation.
Every population experiences genetic drift, but small populations feel its effects more strongly. Genetic drift does not take into account an allele’s adaptive value to a population, and it may result in loss of a beneficial allele or fixation (rise to 100\%100%100, percent frequency) of a harmful allele in a population.
The founder effect and the bottleneck effect are cases in which a small population is formed from a larger population. These “sampled” populations often do not represent the genetic diversity of the original population, and their small size means they may experience strong drift for generations.
Molecules with similar shapes have similar biological effects, because shape (structure) dictates effects (functions).
The image of this question is missing, so i have attached it.
Answer:
Explained below.
Explanation:
From the image attached, we can deduce that;
- The air temperature of Delta will be warmer than Alpha.
- The reason is because the wind will push ocean water that's turning and following the coasts and thereby making energy to be transferred from the ocean to the air at Delta and also from the air to the ocean at Alpha.
