The three types of cloning are recombinant DNA technology (DNA cloning or gene cloning), reproductive cloning, and therapeutic cloning. A wide range of biological materials, such as genes, cells, and organisms have been cloned. Cloning has raised many ethical concerns.
Answer:
The correct option is: A) sympatric speciation
Explanation:
Sympatric speciation is a type of geographic mode of speciation. It refers to the evolution of two or more than two new or descendant species from the existing common descent. The new species and the ancestral species all live in the same geographic area or location.
The common example of this speciation is insects like moths that become dependent on different plants belonging to the same geographical area.
Answer:
We could feed them with another type of food free of silver salts.
Explanation:
When talking about a phenocopy, we are referring to individuals who genotypically should be expressing a determined phenotype, but due to environmental influence, they express another phenotype. This is a non-inheritable phenotype, so it is not considered a mutation.
If we grow thy flies feeding them another type of food that does not include silver salts, and let them mate and reproduce, they will express the real phenotype, because they will not be influenced by the food. In the following generation, there will be dark individuals carrying the dominant allele, and yellow individuals, with the recessive genotype.
