Flashcards in Susceptibility to Periodontal Diseases Deck (11):
1

The magnitude and quality of tissue changes are determined by the bacteria, ________, and ______.

genetics
environmental modifier
(bacteria is necessary but not sufficient for disease)

2

What is mendalian inheritance?

1:1 interaction (monogenic)
having a gene = show the phenotype

3

Conditions caused by many contributing factors are called ______ disorders.

complex/multifactorial

4

Describe phenotypes for a polygenic trait.

the will exist along a wide range (bell curve data)

5

What is a chromosome disorder?

An abnormal condition due to something unusual in an individual's chromosome; such as downs syndrome

6

Describe the characteristics of a Complex Genetic model.

Traits are common in the population
No clear familial transmission
adult age onset
environmental factors
combines many genetic and environmental factors

7

There are many genetic ______ associated with periodontitis.

polymorphisms

8

True or False: A single gene polymorphism may be diagnostic for periodontitis.

False: it is not realistic to expect a single gene to be diagnostic for a complex genetic disease

9

In a complex genetic disorder, each gene is _______.

individually small and cannot cause disease on its own

10

In a complex genetic disorder, at what age is it typically evident?

adult

11

True or False: Disorders within the Complex Genetic Model show clear familial transmission.

False
