What is the concern with wild organisms in terms of health?
lianna [129]

Commercial potential of biotechnology is immense since the scope of its activity covers the entire spectrum of human life. The most potent biotechnological approach is the transfer of specifically constructed gene assemblies through various techniques. However, this deliberate modification and the resulting entities thereof have become the bone of contention all over the world. Benefits aside, genetically modified organisms (GMOs) have always been considered a threat to environment and human health. In view of this, it has been considered necessary by biosafety regulations of individual countries to test the feasibility of GMOs in contained and controlled environments for any potential risks they may pose. This paper describes the various aspects of risk, its assessment, and management which are imperative in decision making regarding the safe use of GMOs. Efficient efforts are necessary for implementation of regulations. Importance of the risk assessment, management, and precautionary approach in environmental agreements and activism is also discussed.

pshichka [43]

Answer:

Sexual reproduction is able to generate genetic variation in offspring by 1-independent assortment and 2-recombination during meiosis, and 3-random fertilization.

Explanation:

Sexual reproduction is a type of reproduction that increases the amount of genetic variation in offspring by three main mechanisms: independent assortment of homologous chromosome pairs and recombination during meiosis, and random union of gametes during fertilization. First, sexual reproduction is associated with the independent assortment of chromosomes during meiosis, i.e., the orientation of homologous chromosome pairs is a random process that is different for every cell that undergoes meiosis. In consequence, chromosomes assort randomly into gametes, thereby the segregation of alleles of a gene pair is independent of the segregation of another set of alleles of a different gene (as stated in the law of independent assortment). Second, sexual reproduction generates genetic variation by recombination, which is the exchange of genetic material between non-sister chromatids during meiosis I (prophase I). This genetic process (recombination) is able to generate new alleles in offspring. Third, sexual reproduction also involves the random union of two haploids (n) gametes during fertilization, which results in the formation of a diploid (2n) zygote that develops into a new individual. In humans, the sperm cell has 8 million possible (2²³) chromosome combinations, which fertilizes an ovum cell that also has approximately 8 million chromosome combinations, thereby producing a tremendous genetic variation in offspring (around 64 trillion possible zygote combinations).
