How can an organism benefit from asexual reproduction?

1 answer:

8 0

The reproduction asexual refers to the time when an organism one cell follows and that is capable of forming an individual identical to the original organism. Nuclei of sex cells or gametes do not intervene in this type of reproduction. There is only one parent. Even so, science is trying to use this knowledge about asexual reproduction to apply it from a medical point of view in aspects that can be much more positive and important for the life of the human being. One of these applications and, perhaps, the most important, is to create clones of tissues and organs of any person from cells. This opens up an infinity of possibilities, one of the most important applications being that of organ transplants

Alenkasestr [34]

Answer:

Note the fragments from DdeI restriction –

I. AA individuals have two copies of normal b-globin allele.

b-globin allele ----DdeI-----------> 176 bp + 201 bp + 600 bp

Since there are two copies of b-globin allele, the restriction of AA genome would produce 2 copies each of 176 bp, 201 bp and 600 bp fragments.

II. AS individuals have one normal and one mutated copy b-globin allele. So, following fragments would be obtained -

b-globin allele ----DdeI-----------> 176 bp + 201 bp + 600 bp

b-globin allele ----DdeI-----------> 376 bp + 600 bp

So, for such genotype, four fragments of MW as shown above would be produced.

III. SS individuals have two mutated copy b-globin allele. So, following fragments would be obtained -

b-globin allele ----DdeI-----------> 376 bp + 600 bp

So, for such genotype, two copies each of the fragments of MW as shown above would be produced.

Answer:

It will decrease their ability to exchange air into and out of the lungs, decreasing gas exchange.

Explanation:

Muscular dystrophy is a rare genetic disease of the skeletal system which occurs early in childhood. Other symptom of muscular dystrophy include impaired learning,muscle stiffness and pain. The rib cage protects and houses the lungs. When the muscle of the rib cages gets impaired then it affects how gases are inhaled and exhaled.
