Whole-genome sequencing can be used for advances in:
Mariana [72]

Answer:

all of the above

Explanation:

When the human genome was sequenced, one of the first information generated was related to the structure of the genetic material. For example, it has been found that there are long repeated sequences in different parts of the DNA or regulatory parts of its functioning in other parts of the genetic material itself.

When determining the order of nucleotides of a living being and comparing it with others of the same species, we find some regions that accumulate more differences than others, that is, are more diverse than others. Very similar sequences, that is, conserved in all living beings of the same species, can determine essential characteristics of these organisms. These essential characteristics can be very important for many different sectors and improve the lives of humanity in unimaginable ways.

The discoveries made through the complete sequencing of a genome can cause immense improvements in the fields of medicine, agriculture, biofuels and many other fields.

Explanation:

                     Male reproductive system produce gametes in the testis which is the part of male reproductive system. Testis are two in number normally which compose of seminiferous tubules which have spermatogenic cell which are responsible for the production of spermatids with the help of sertoli cells present in the seminiferous tubules.After production  of gametes the spermatid are delivered to the female reproductive system by copulating organ which in human is penis.the sperm 1st produces in the semeniferus tubules then transfer in to the rate testies ,epidydemis then vas deference and then urethra and then outside the body.
