The soil on a valley floor
The soil on the hillside can roll down because of rain, landslides, etc , and so it would continue to develop in the areas
The soil in the valley floor, however, should be staying in the same condition for most of the time
hope this helps
Answer: If crossing over did not occur during meiosis, there would be less genetic variation within a species. ... Also the species could die out due to disease and any immunity gained will die with the individual. Two types of gametes are possible when following genes on the same chromosomes. If crossing over does not occur, the products are parental gametes. If crossing over occurs, the products are recombinant gametes.
Explanation:
Probability = number of possible outcomes / total number of outcomes
Genetic engineering is due to the human selection of desired phenotypes, whereas natural selection is a slow process of differential survival and reproduction.
<h3>What does natural selection mean?</h3>
According to the evolution theory, natural selection is a slow process of differential survival of the fittest organisms in a given environment.
Conversely, genetic engineering refers to the molecular biology techniques used in the laboratory to produce organisms expressing desired phenotypes.
In conclusion, genetic engineering is based on human molecular biology techniques, whereas natural selection refers to differential survival and reproduction in nature.
