Atrait is a feature or quality of an organism. all organisms have a unique set of traits that they inherit from their parents. each parent supplies one half of the needed to determine the traits of their offspring.

chromosomes.

Explanation:

Chromosomes are structures formed by DNA that are located in the nucleus of the eukaryotic cell. It is also on the chromosome where the genes are located.

The number of chromosomes varies from species to species. In humans, there are 46 chromosomes in somatic cells (all cells in the body except reproductive cells). In reproductive cells, there are only 23 chromosomes, half the number of the species. This is important because at the time of fertilization, sperm and oocytes fuse together, so the number of chromosomes is restored. In this case we can state that during human reproduction each parent provides half of the chromosomes needed to determine the characteristics of their children.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

common management practices in dairy and poultry farming are: (i) proper shelter facilities and their regular cleaning. (ii) some basic hygienic conditions such as clean water, nutritious food, etc. (iii) animals are kept in spacious, airy, and ventilated place.
