Answer: Polygenic means that most traits are controlled by an additive effect of two or more genes on a single phenotype.

Explanation: Polygenic inheritance or quantitative characters are those that vary in the population along a continuum. For example, height, skin color, etc.

Often, penetrance, pleiotropy, epistasis, expressivity and environmental factors are involved in producing a continuous distribution of phenotypes.

Traits such as height that show a continuous range of variation and do not behave in a single Mendelian fashion are known as quantitative or complex traits.

What do you notice is the main difference between the structure of the connective tissues and the structure of the epithelium? m
FinnZ [79.3K]

The connective tissues and the epithelial tissue differ in their structure in the way their cells are organized. The cell of the epithelial tissue are organized in a closed-packed pattern, while the cells of connective tissue are organized in spread out pattern. Moreover, the connective tissues has blood vessels, but the epithelial tissue does not.

The epithelial tissues serve the purpose of protection. Protective layering is formed by the epithelial tissues in the body. The connective tissue such as bone provides support to the body. The blood vessel connectivity helps in the transfer of the newly formed blood cells.

The appearance of a person is determined by the tissues and other components. The skeletal determines the basic structure of the person. The epithelial tissues give more specificity to the figure of a person. The fats helps in determining the shape of the eyes and cheeks.

The fat in the cheeks is supposed to help the new born infants to suckle and chew. Moreover, it provides padding to the temporalis muscle while chewing. The fat behind the eyes helps in preventing damage to the eyes which may be caused if they rub with the bones of the skull.

It will be hard to open and close one's mouth if the temporalis muscle of a person is damaged. This will make forming words properly difficult. The damage to orbicularis oculi will make the blinking extremely difficult. The facial expressions will be distorted in such cases. The damage to the orbicularis oris will make the movement of the mouth difficult, which will cause poor articulation.
