D)None of the above

Answer 1

A

Question 2

Consultation with a genetic counselor may be helpful for speech-language pathologists and audiologists if their client has

A)Traumatic brain injury
B)Tongue thrust
C)Pierre Robin Syndrome
D)Aphasia

Answer 2

C

Question 3

Syndrome

A)A recognizable pattern of abnormalities that indicate a particular trait or disease
B)The visible pattern of an organism's chromosomes
C)Slight variations in our genes that contribute to individual differences
D)The sum of all genes,estimated to contain 30,000 genes

Answer 3

A

Question 4

Human genome

A)A recognizable pattern of abnormalities that indicate a particular trait or disease
B)The visualization of an organism's chromosomes
C)Slight variations in our genes that contribute to individual differences
D)The complete set of genes,estimated to be 30,000 in number

Question 5

Constructing pedigrees for a family that has a child with a genetic disorder is one clinical service provided by audiologists and speech-language pathologists.

Question 6

Highly expressive traits are seen in one child to higher degrees than they are seen in siblings.

Question 7

Each time a gene is passed from one generation to the next,some alterations occur.

Question 8

Chromosome 1 is the largest human chromosome but has the fewest number of genes.

Question 9

Slight variations in our genomes that are responsible for our individual differences and predisposition to disease and disorder are called

A)SNPs small nucleotide proteins)
B)SNPs single nucleotide polymorphisms)
C)MMPs multiple nucleotide polymorphisms)
D)MNMs multiple nucleotide mutations)

Question 10

Gene expression refers to the passing on of traits from parents to children.

Question 11

Research linking genetics with communication disorders include identifying genetic markers for speech delay,laryngeal paralysis,and autism.

Question 12

The Gene Expression Nervous System Atlas GENSAT)helps investigators understand which genes are critical in the nervous system and how they function.

Question 13

Changes within genes can produce proteins that don't work normally or don't work at all,which may result in disease or disorder.

Question 14

Recessive inheritance

A)Inheritance is passed on to children by both parents
B)Inheritance is passed on to children by one parent
C)Inheritance is not passed on to children
D)Inheritance is passed on to children,but symptoms are not expressed

Question 15

Genes

A)A set of 46 rod-like structures in the nucleus of a cell composed of DNA and protein
B)Specific units of DNA that determine and transmit hereditary characteristics from parent to offspring
C)Carry DNA's instructions for protein formation
D)Structural,functional or metabolic abnormalities

Question 16

Genetics

A)A branch of biological science that examines the role of communication in disease and disorder
B)A branch of biological science that studies the inheritance and function of genes
C)A branch of biological science that describes the development of communication disorders
D)A branch of physical science that describes the acoustical properties of communication

Question 17

Genes are composed of DNA and are found on specific locations of the chromosomes.

Question 18

Birth defects

A)Are characterized by structural,functional or metabolic abnormalities
B)Occur in approximately 150,000 babies each year
C)May lead to communication disorders
D)All of the above

Question 19

Specific genes have been associated with deafness and Alzheimer's disease.

Question 20

Dominant inheritance

A)Inheritance that is passed on to children by both parents
B)Inheritance that is passed on to children by one parent
C)Inheritance that is not passed on to children
D)Inheritance that is passed on to children,but symptoms are not expressed

Question 21

Speech-language pathologists and audiologists may consult with genetic counselors to assist families with preventing some communication disorders.
