Essentially traits of both genes will be shown. Take heterochromia for example, where a person has a green eye and a blue eye, both have some part in developing a trait.

I answered a similar question before so I'm going to use an example from there. Two plants, a dark purple flower and a white flower create an offspring with dark purple and white petals on the flower. This is an example of the gene displaying codominance in effect.

Codominance allows for two genes to exist independently at the same time without mixing. Think of another example. Say your mother has blue hair and your dad has red hair. If you have both blue and red strands. That is codominance. The two colors who co-exist. If you got purple, you would have incomplete dominance. Notice that the purple is a mix and of blue and red. They are dependent on each other.

Hope that helps! :D

What is an advantage of performing a series of dilutions vs. a simple dilution?

Marrrta [24]

Answer:

The series dilution method is the step wise dilution technique where the dilution factors remain constant in each step.

The advantages of using the series of dilution method over simple dilution are stated below:

a) Aids in reduction of a dense culture of cells to a more usable concentration.

b) In every step of dilution the specific amount of bacteria is removed. 

c) Helps in the estimation of concentration of an unknown sample.

This sums up the advantage of using the series dilution technique.

Why is it necessary to complete the identification of a bacterium based?

Neporo4naja [7]

The trouble with identifying bacteria is that a lot of them look exactly the same. So, identifying by shape and such will only get you so far. However, two kinds of bacteria that look exactly the same under the microscope could have very different physiologists. One may be able to use a certain sugar as an energy source while the other one cannot, for example. Therefore, you can use morphology (physical characteristics) to narrow down the possibilities, but then you must complete the identification using the bacteria's physiology.
