Answer: A trait that masks another trait is called dominant trait.
A trait is a characteristic or a morphological form that is expressed in an organism. There can be two different types of traits according to Mendelian genetics that is Dominant and Recessive trait. They are expressed due to two different forms of a gene that is called allele.
A dominant allele usually represented by capital letter like T for tall, corresponds to dominant trait and this masks the expression of recessive trait. Example- Tall plant height.
On the other hand, recessive allele is represented by small letter like t for dwarf and corresponds to recessive trait. This trait does not express in the presence of dominant allele.
Example- Dwarf plant height.
Hi there!
It is necessary to rinse the inside of an Erlenmeyer flask with deionized water periodically to wash the flask without adding ions which could affect the titration.
If you wash an Erlenmeyer flask with regular tap water, you are adding ions, like sodium or chlorine, which could make you miss the equivalence point by only tenths of mL (that's a big difference when titrating). This is why when washing you use deionized water to clean the flask while ensuring that your titration is accurate.
Have a good day!
