Gn 301 Test 2

Front 1

Testicular Feminization

Back 1

Female with xy chromosomes intersexed with testes in the abdomen that produce sperm but can never be activated. Female features. Faulty x-chromosome. It causes developmental confusion.

Front 2

Mutagen

Back 2

any agent which elevates the mutation rate above the spontaneous level. ie. x-ray, gamma ray, UV, sudden temp chgs.

Front 3

Y-linked characteristic

Back 3

characteristic that develops from the same chromosome. In this case Y-male development control gene TDF/SRY.

Front 4

Gene interaction

Back 4

when 2 or more loci interact and give an enexpected phenotype.

Front 5

Frameshift mutation

Back 5

addition or deletion of 1 or more base pairs

Front 6

On keeping our genes clean

Back 6

Dr.McKenzie's Presentation to the Watauga Club on genetic mutations->due to environmental/mutaGEN,carcinoGEN/teratoGEN/conditions or exposure

Front 7

Barr Body

Back 7

Inactive x-chromosome

Front 8

Adrenal Virilism

Back 8

condition caused by overproduction of male/male like hormones

Front 9

Albinism

Back 9

autosomal RECESSIVE characteristic involving a block in the pheylalamine metabolic pathway

Front 10

Reduced Penetrance

Back 10

Not all Pp individuals are polydactylous

Front 11

Hemizygous Dominant

Back 11

male with normal red-green color vision

Front 12

Kline felter syndrome

Back 12

Individual with an extra x-chromosome, xxy karyotype

Front 13

Turner Syndrome

Back 13

Condition where an individual is missing a sex chromosome, ie. has and xo karyotype

Front 14

TDF/SRY

Back 14

Y-linked male development control gene
