Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

If the overall diversity of a population is measured that had gone through a recent bottleneck and then rapidly recovered its former population size, it would have a lower than expected diversity based on its population size.
<h3>What is Population Bottleneck?</h3>
- A population bottleneck is a situation where the population is substantially reduced. A variety of occurrences, such as an environmental catastrophe, the extinction-level hunting of a species, or the destruction of an organism's habitat, might result in the bottleneck.
- Due to the loss of many alleles, or gene variants, present in the initial population, the population's gene pool decreases as a result of the population bottleneck.
- The event has resulted in an extremely low amount of genetic variation in the remaining population, which indicates that the population as a whole has few genetic traits.
- When a population bottleneck occurs and there are alleles present, the residual population is more susceptible to genetic drift.

Answer:
The wise use of crop genetic diversity in developing improved crops can contribute significantly to protecting the environment. Crop varieties that are resistant to pests and diseases can reduce the need to apply harmful pesticides. More vigorous varieties can better compete with weeds, reducing the need for applying herbicides .
