Light and dark moth natural selection experiment

Biology
1 answer:
S_A_V [24]3 years ago
3 0

Answer:

The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism. Later, when pollution was reduced, the light-coloured form again predominated. Industrial melanism in the peppered moth was an early test of Charles Darwin's natural selection in action, and remains as a classic example in the teaching of evolution.[1][2] In 1978 Sewall Wright described it as "the clearest case in which a conspicuous evolutionary process has actually been observed."[3][4]

The dark-coloured or melanic form of the peppered moth (var. carbonaria) was not known before 1811. After field collection in 1848 from Manchester, an industrial city in England, the frequency of the variety was found to have increased drastically. By the end of the 19th century it almost completely outnumbered the original light-coloured type (var. typica), with a record of 98% in 1895.[5] The evolutionary importance of the moth was only speculated upon during Darwin's lifetime. It was 14 years after Darwin's death, in 1896, that J.W. Tutt presented it as a case of natural selection.[6] Due to this, the idea widely spread, and more people believed in Darwin's theory.

EastWind [94]
DNA mutations that actually originate in the gametes is mainly responsible for genetic biodiversity existing in modern organisms. The term biodiversity actually refers to the variety as well as variability of life that is found on the planet earth. his variety can be seen between species, the ecosystem and within the species.<span />

xenn [34]

Answer:

<em>The correct option is D) need to be aware that if any of his garlic plants became diseased, it could very likely infect the entire crop</em>

Explanation:

If cloves from a bulb are taken and grown, then the plants formed will be identical to each other. As a result, there will be no genetic varieties in the garlic plants being produced. Hence, when a diseases eradicates, it will affect the entire plants of the garden as they would be genetically identically, Variations would have allowed some of the plants to be resistant for the disease and hence some of the plant species could be saved by genetic variations.
