A paragraph on how selective breeding is better than cloning plz 100 POINTS
harkovskaia [24]

Answer:

Selective breeding is used to promote the benefits of both animal and plant breeding inheritance. It is essentially done by controlled breeding. However, it has its own set of disadvantages, like any other agricultural method-although it is supposed to offer benefits to society. If you want to selectively breed your crops and cattle, weigh them down and decide whether that’s a good way for you.

No company patent is required.Anyone working in farming can start breeding selectively whenever they want. It is a way for him to create more profits every year, as he can grow animals and plants with different characteristics such that they can be generated over centuries, which is good for businesses. And since he is free, he only needs to be knowledgeable and well equipped in the process to achieve the best result.

It makes higher profit possible.Selective breeding encourages more beneficial plant and animal characteristics for farmers. If they have selectively bred cows, for example, these animals can produce more milk than the typical cows and the gene can be transferred to their descendants. If the method is used on crops, more than the typical ones will also be grown. Promoting these advantages will certainly increase their product’s market value. Selective breeding is certainly an perfect choice for farmers who are in a major company.

Mitochondria and chloroplasts have a number of features in common. Which of the following is NOT one of them? (A: Both are surro
likoan [24]

The best answer is C.

Chloroplasts are not found in all eukaryotic cells but only in plant cells. Animal cells are eukaryotic in nature but animals do not have chloroplasts in their cells because they do not engage in photosynthesis.

Photosynthesis is the process by which plants make their own food. Chloroplasts  contain chlorophyll which is essential in t trapping sunlight from which supplies the energy for photosynthesis. 

Animals do not make their own food like plants but eat ready made food so their cells  lack mechanisms for food manufacture.

After hundreds or even thousands of generations both alleles for sickle cell anemia are still common in those of african ancestr
zhannawk [14.2K]
After hundreds or even thousands of generations both alleles for sickle cell anemia are still common in those of African ancestry. This is supported by two mechanisms: heterozygote advantage and gene flow.

Heterozygote advantage
When an allele is said to be heterozygous, it is carrying one copy of a gene. For example if one carries a copy of sickle cell allele, it will stay in the population even after many generations — natural selection will not be able to remove it and it will be passed on through generations. So, having one copy of that allele is advantageous but not deleterious.

Gene flow
With humans migrating throughout the different parts of the world, sickle cell allele is passed from one person to another or in different populations. It is actually advantageous to have one copy of this allele especially if there’s malaria in the area, which the allele is resistant.
