What is the smallest number of traits that are needed to test Mendel's law of independent assortment?
Two traits are needed to test Mendel's law of independent assortment, such as seed color and seed shape in pea plants. By observing the inheritance of these two traits in offspring, one can determine if they are inherited independently of each other, which is a key principle in Mendel's law of independent assortment.
What did Gregor Mendel test for?
Gregor Mendel tested for inheritance patterns in pea plants, specifically looking at traits such as seed shape, flower color, and plant height. His experiments helped establish the basic principles of heredity and laid the foundation for modern genetics.
Why is important to inoculate a single tube per organism when performing a MRVP test?
Inoculating a single tube per organism ensures that the test results are specific to that particular organism. Mixing multiple organisms in one tube can lead to inaccurate results due to potential interactions or competition between the different organisms during the test. Keeping the organisms separate helps to maintain the test's reliability and accuracy.
What is the purpose of sodium azide in the Bile Esculin test?
Sodium azide is included in the Bile Esculin test to inhibit the growth of Gram-negative organisms, which could interfere with the test results. Sodium azide helps to maintain a selective environment that favors the growth of group D streptococci, the target organisms for the test.
What experiment did mendel perform to test inheritance?
a. purebred crosses b. dihybrid crosses c. monohybrid crosses d. testcrosses (B)
