Answer: A short incubation time runs the risk of a false negative on the VP test, since not enough time may have elapsed to produce an adequate amount of acetoin to give a positive result. The pH change associated with mixed acid fermentation occurs fairly quickly and is less likely to be affected by shorter incubation.
b) The VP test would benefit most from a longer incubation time because it takes a while for the 2,3-butanodiol to be produced.

Answer:
Explain how genes are expressed for a particular trait?
Genes are expressed phenotypically as it reflects through dominant gene which are represented through physical means such as height, skin color, shape e.t.c
Explanation:
Answer:
The cell type I work with (chondrocytes) are really similar between different species. The tissue they make is very similar between species and that is why they are a great model for looking at human joint tissues. In terms of the basic elements of the cell, all animal cells are very similar, i.e. they do not have a cell wall and they have a nucleus. Dogs have different features to us because they have adapted and evolved to have the features they have. For example, when a puppy is developing, cells receive signals to move to one end of the puppy and develop the tail. A long time ago our ancestors had tails but over millions of years we have lost that feature because we don’t need it to survive.
