what is the difference between conjugation and human reproduce?

Question

need helpp !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
please answer will be very helpfull!!!

Answer 1

Conjugation is the bacterial equivalent of human reproduction.

Bacterial conjugation is the transfer of DNA from one cell to the other, usually by direct cell contact. This is in the form of a plasmid (small circular DNA) which serves to compliment the genome. An example would be antibiotic resistance. A small plasmid for antibiotic resistance can be passed from one bacterial cell to another. It creates genetic variation

Human reproduction also creates genetic variation, but quite differently. As you know human reproduction is the fusion of sperm and egg. Both are haploid (half the genome) and become diploid (the whole genome). Depending on which sperm fuses with which egg the genome can be vastly different. Just look at brother and sisters.

A more in depth explaination of "bacterial conjugation" can be found on wikipedia

Answer 2

Taxonomically advanced animals like humans reproduce sexually by the fusion of heterogametes (specialized cells that are dissimilar) , e.g., sperm & egg. The monoploid gametes form a diploid zygote.
Lower forms of life reproduce by a relatively primitive form of sexual reproduction called conjugation. This process involves the entire organism, not specialized cells. Some examples: Paramecia align themselves side- by -side, exchange micronuclei (isogametes, as opposed to heterogametes in higher forms) through their
oral groove. The exchanged micronuclei divide, and each paramecia proceed to split by binary fission. Conjugation seems to be a kind of rejuvenation process , giving them more resistance to environmental stresses and extending their life span. It also allows for genetic variation, not afforded by asexual reproduction (like binary fission) alone.

Spirogyra (green algae) strands line-up side-by-side, a conjugation tube grows between them . The contents of one cell (called the active or positive strain, not called male)moves through the tube into the adjacent cell (the passive strain, not female) and forms a "zygospore". This zygospore, or primitive zygote, eventually
produces a new strand or filament of Spirogyra.

Bread mold (Rhizopus) , a fungus, similarly forms a conjugation tube between two hyphae, producing a zygospore.

I believe that yeast (a fungus) are also capable of a form of conjugation. Usually though, they just reproduce asexually by budding.

Answer 3

In humans, the gametes (egg and sperm) have to fuse. However, in congutation, DNA is transmitted without fusion of gametes.
