Question

Genetic Technology: Write a scientific explanation to explain the multiple technologies that humans

can use to affect traits in organisms. Use evidence to describe the processes and give examples. Give
at least two examples

Answer 1

Examples of genetic technologies:

- High-yield maize varieties by conventional breeding

- Production of hormones by transgenic or genetically engineered microbes

Step-by-step explanation:

Genetic improvement refers to the use of technologies in order to develop and select individuals with desired phenotypic traits. These genetic technologies can be divided into 1-conventional genetic improvement approaches based on the development of individuals (e.g., new plant varieties) by crossing together individuals with desired characteristics and subsequent rounds of artificial selection, and 2-modern genetic technologies where genes are directly manipulated in the laboratory through genetic engineering technologies such as, for example, the use of transgenic methods (e.g., DNA microinjection, retrovirus-mediated gene transfer, etc), or the CRISPR-Cas9 genome editing system (which can be used to edit target genes of interest), etc.
