I remember seeing this so i thought i would share

Genetically modified foods, also known as genetically engineered foods, or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering.

The most common GMO crops include soybean, maize, cotton, canola, and alfalfa. The following GMO crops were also planted in different countries in 2018: papaya, eggplant, potato, apple, safflower, pineapple, and sugarcane.

For centuries, farmers have bred crops for certain desirable traits. Genetically Modified (GM) crops offer improved yields, enhanced nutritional value, longer shelf life, and resistance to drought, frost, or insect pests.

Genetic modification of plants involves adding a specific stretch of DNA into the plant's genome, giving it new or different characteristics. ... The gene of interest is transferred into the bacterium and the bacterial cells then transfer the new DNA to the genome of the plant cells

GMOs have helped farmers reduce their environmental footprint by allowing them to use fewer inputs and enabling a shift to reduced tillage. These practices have led to less time spent on a tractor, less fuel used and fewer emissions.

Answer:

Genetic modification decreases the genetic variation of the modified organism.

Explanation:

Genetic modification is widely used in agriculture for increasing productivity and to make crops resistant to diseases but along with advantages there are some disadvantages of genetic modification that involve decreases the genetic variation of the modified organism.

<em>This is so because the DNA or genetic material of the modified organisms will have very less diversity as they have grown with the same process and the DNA among the organisms will become similar to each other.</em>

Hence, the correct answer is "Genetic modification decreases the genetic variation of the modified organism."

The presence of paired chromosomes makes a <u>diploid </u>cell, while a single member of a pair of chromosomes makes a<u>haploid </u>cell.

Diploid cells. Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number. </span>

Some organisms undergo asexual reproduction through mitosis, while others reproduce sexually, and their cells undergo meiosis to
Sav [38]
The answer is <span>A. Meiosis: It increases genetic variation, which helps ensure the species will survive.

Meiosis increases genetic variation. This means there is a great variety of genotypes among the population. Hence, there are organisms able to survive in a wider range of temperature. If </span><span>there were drastic changes in temperature in an ecosystem, some of the organisms will survive because their genotype allows them to live in such conditions. If there were no variety thanks to meiosis, all of the organisms would die. And that is not beneficial to a species.
Imagine on the other hand that mitosis occurred. Mitosis does not provide a variety of genotypes and all of the organism will be the same. </span><span>If there were drastic changes in temperature in an ecosystem, all of the organisms would die because all of them could respond to the change in the same way.</span>
