401 of these offspring are expected to have long plumage.
To calculate the number of these offspring that are expected to have long plumage the following cross multiplication calculation must be performed:
- Total birds = 72 + 252 = 324
- Long plumage birds = 55 + 75 = 130
- 324 = 130
- 1000 = X
- 1000 x 130/324 = X
- 130000/324 = X
- 401.23 = X
Therefore, 401 of these offspring are expected to have long plumage.

The variation that involves contracting each muscle group repeatedly with progressively less tension with each contraction is incremental muscle relaxation.
<h3>What is incremental muscle relaxation?</h3>
Incremental muscle relaxation is a type of variation during a physical exercise aimed at relaxing the muscles.
Incremental muscle relaxation is a fundamental component in any training exercise program.
Incremental muscle relaxation consists of relaxing certain groups of muscle fibers that have undergone rhythmic contractions.
