Visualization: A Closer Look at Low Endurance Horses

Let’s observe another animated model to understand what happens to the genetic information for a horse that inherited two different alleles from its parents – a high endurance allele and a low endurance allele.

How does the genetic information get expressed into muscle fibers?

As you observe the animated model below, write five ideas, one about each of the following:

• the allele combination
• the role of the messengers
• the role of the ribosome
• the role of protein(s)
• the proportion of high and low endurance muscle cells.
