Answer:

The correct answer is option A- "Tampering with nature by mixing genes among species".

Explanation:

The advent of genetically engineered crops had bring several benefits including crops with resistance to adverse environment conditions and diseases. However, there are ethical considerations that should be taken into consideration before genetically engineered crops are released to the market. One of the considerations is the risk of tampering with nature by mixing genes among species. Crops transfer their genes constantly in nature, therefore is important to have the genetically engineering crops in confinement to avoid that genes could be mixed among species in nature.

If Darwin knew of Mendel’s work, how might it have influenced his theory of evolution? Do you think this would have affected how
Viktor [21]

Answer:

See explanation

Explanation:

Darwin proposed his theory of evolution on the premise of natural selection. According to him, organisms which possess favourable characteristics which enable them to survive in their environment are more likely to survive and reproduce, passing on these favourable characteristics to their offsprings.

According to Mendel, the unit of inheritance passed on from parents to offspring are genes. Hence Darwin's factors are Mendel's genes.

If Darwin knew of Mendel's work. It might have influenced his presentation of the idea of passing on favourable characteristics from parents to offspring in the light of genetics.

This would have made Darwin's work to have more empirical backing hence making it more widely accepted.
