Answer:
Symbiotic relationship
Explanation:
An average human body between 20 to 30 year of age with a weight of 74 kg and 170 cm contains about 30 trillion cells. The number of bacterial cells in the same man counts for about 39 trillion that is higher than the cell of the body.
The ratio between the bacterial cell to the human cell is about 1.3:1 which is almost equal or higher than the human cells.
Although the number of bacteria is almost equal or higher than the human cell, the main reason behind this relation is that these bacteria live in the symbiotic or mutually beneficial relationship with humans.
Thus, a Symbiotic relationship is the correct answer.
Varieties of plants in which self-fertilization produces offspring that are identical to the parents are referred to as true-breeding. In this process the parents will pass down specific phenotypic trait of their offspring. True bred organisms will have pure genotype (genetic make up of an organism) and will therefore produce certain phenotype.
