A defective allele is more likely to be eliminated from a population if it is dominant. This is because it is immediately exposed to the effects of selection, as only one copy of a dominant allele is needed for it's characteristic to be developed.
If an allele is recessive it can survive in a population as it is 'hidden' from selection by the presence of the corresponding dominant allele. It will only beexposed to selectionif an individual inherits the recessive allele from both parents. If the recessive allele is rare, the chances of two individuals with the allele mating could be quite small. In this way a defective recesssive allele could survive at low levels in a population.
Prokaryotes evolve rapidly compared to eukaryotes because they have shorter generation times, larger population sizes, and higher mutation rates, allowing for quicker adaptation to changing environments.
The close proximity of people in crowded urban areas increases the likelihood of rapid disease transmission. High population density can facilitate the spread of infectious diseases and make containment efforts more challenging. Public health interventions must be efficient and timely to prevent a slow outbreak from escalating quickly in such environments.
Our population has rapidly grown and is still rapidly growing because we keep getting more and more babies it is said that every 5 seconds a new person is born. This is the reason that we have so many people walking on this earth and if people keep reproducing then we will run out of space on the earth for them to live, also we will run out of natural resources and food.
Slowly growing countries typically have a more uniform age distribution with a steady increase in population across different age groups. In contrast, rapidly growing countries often have a pyramid-shaped age structure with a larger proportion of younger individuals compared to older individuals. This reflects higher birth rates in rapidly growing countries leading to a larger population of children and youth.
When an organism reproduces quickly, the population increases rapidly. This can lead to competition for resources like food and space, potentially causing overcrowding. In the long term, it can result in environmental degradation and increased vulnerability to disease or predation.
Your "turn solenoid" is defective.
The mutation that has the greatest effect is one that is not only beneficial but that is heavily selected for by the environment. Ideally dominant as it will effect the population more rapidly than a recessive trait. Only traits that are selected for or against in a population change the frequency of the occurance of the alleles in the population.
It decreases rapidly.
The most rapidly increasing population is India the population is expected to overtake China by 2030. The most rapidly decreasing population is Latvia it's growth rate is -18.
Kenya
r-selective population
1,370 is the current population, rapidly decreasing
The population started to increase rapidly
It would be the opposite of a population explosion. The population would decrease drastically and rapidly instead of increasing.
Why world's population has increased rapidly in last hundred years and main problems will cause?
food and water shortage
They had good farming
