F Ff Ff
f ff ff
There are two Ff and two ff
Thus, the percentage of their offspring that would be expected to have feather shanks is 
100 = 50%
The test organism ferments sucrose best under reduced oxygen conditions.
The sample was incubated less than 24 hours, which allowed for only limited fermentation.
The media was contaminated.
The organism is an obligate aerobe and therefore can only grow inside the Durham tube.
The media was prepared wrong.
The organism is limited in its ability to ferment sucrose. Since diffusion is restricted within the Durham tube and it contains only a small volume of media, it turned yellow first.
The test organism did not ferment sucrose.
1)The test organism ferments sucrose best under reduced oxygen conditions.
2)The sample was incubated less than 24 hours, which allowed for only limited fermentation.
3)The organism is limited in its ability to ferment sucrose. Since diffusion is restricted within the Durham tube and it contains only a small volume of media, it turned yellow first.
The long-run aggregate supply curve will shift to the right if a given economy experiences technological advancements.
<h3>What is the aggregate supply curve?</h3>
The aggregate supply curve is a graphical representation that makes reference to all processes that add value to the productive chain.
The aggregate supply curve is mainly influenced by technological inputs that increase productivity.
In conclusion, the long-run aggregate supply curve will shift to the right if a given economy experiences technological advancements.
