The random change in allele frequencies is called ____________ . Genetic drift can lead to the fixation of an ____________ and o
ccurs rapidly in ____________ populations. When populations are reduced following a major disaster the resulting random change in allele frequencies is called the ____________ . If the population returns to its pre-disturbance size, genetic variation is generally ____________ than in the original population.
1. Genetic drift refers to the random or uncontrolled process which changes the allele frequency and becomes one of the evolutionary force like a natural catastrophe.
2. This lead to the fixation of the allele in the population as the selected population with allele survive.
3. The process of genetic drift is observed in the small population as the small population is easily affected by the natural catastrophe.
4. Bottleneck effect is observed when the large portion of the population is eliminated and the surviving allele of the living population is passed on to the generation.
5. If the population returns to its pre-disturbed state then the genetic variation is lower in the population as compared to the original population because the population genetic drift eliminates the allele and changes frequency.
<u>'Roll call vote'</u> in simple simple terms is described as the trend when each member's vote is being recorded. Such a voting reflects the unity in a party as their votes are officially taken into account. These votes are also known as 'recorded votes' and these votes are often called when it is requested by at least one-fifth of a quorum of legislators. Such a voting reflects that how the legislators(representatives) have voted on specific grounds. Thus, 'roll call vote' is the answer.
The cement company most likely embrace the idea of sustainable development.
Explanation:
Companies use sustainable methods of production to reduce the harmful impact of the company's processes on the environment. This does not only help the environment but also helps the business in gaining customer trust and loyalty as customers are more inclined to businesses involved in ethical production practices. Also, it gives an competitive edge and improved the company's image.
