Description
-
Put one strip on your tongue for 10 second and if you taste bitterness you have this characteristic homozygous dominant or heterozygous
-
100 x 1.75 inch pre-cut strips (which can each be cut in half) enable you to test all of your friends, family, and classes very economically
-
Perfect for demonstrating genetic pedigrees and learning about genotypes and phenotypes
This
product is all you need for a demonstration of genetics and heredity.
These strips can be used to help determine if a person is a ‘supertaster’
and can be used to effectively demonstrate the effects of heredity on
taste. PTC (pheylthiocarbamide) can help you gain an understanding of
someone’s genetic pedigree. The strip can taste anywhere from bland to
incredibly bitter for individuals depending on their genotype and
phenotype.
PTC
Paper has been used widely since its discovery to detect genetic variation
in tasting abilities. Phenylthiocarbamide (PTC) is a chemical which causes
a bitter flavor to some people. This is a genetic variation which normally
occurs in a ratio of 75% who can taste PTC versus 25% of those who cannot.
Research suggest it is related to an enzyme which is produced by cells on
the tongue. Though not essential for survival, this condition might
explain why some people are more sensitive to bitter tastes than others.
Instructions:
1.Remove a PTC taste test paper from the vial.
2.Stick out your tongue, and place the strip on your tongue.
3.There are three basic results: bland, bitter, or vile.
PTC
Taste Test Paper is perfectly safe to use. Any possible toxicity of PTC
would be in grams per kilogram of body weight, which is millions of times
greater than anything which would be found in our taste test strips.
Phenylthiocarbamide (PTC) is present at only 20 micrograms per strip. At
this level, the compound is negligible and harmless.
