Conjugation is the transfer of genetic material between two bacteria. It is referred to as horizontal gene transfer as it occurs through the formation of a horizontal connection or a pilus.
Conjugation occurs when the donor bacterium, containing the fertility factor (F factor; it is the gene required for pilus formation) initiates pilus formation.
This tube-like structure then joins the two bacteria and transfer of genetic material occurs.
Plasmids containing antibiotic resistance genes are also transferred in this manner.
A heterozygous cat has a genotype Hh A hairless cat has a genotype hh When crossed, the results could be any of the following: Hh (with hair) hh (hairless) There is a 50:50 chance or 1: 1 ratio that the offspring will have hair.
One way in which classification is used at school is the separation of different subjects and subject materials. For instance one day you may go to a math class, while another day you may go to a french class.
