<span>Catalase is a common enzyme very important in reproductive reactions and is found in almost all living organisms exposed to oxygen. There are different catalase activities, pH optimum of which between 4 and 11 depending on the species. However, the optimum pH for human catalase is approximately 7.0 (letter C). </span>
C. Because ecosystems consist more of animals
Crossing a BB male with a Bb female:
The Punnett Square will look like this:
BB BB
Bb Bb
The percentage will be as follows:
- You will have 50% homozygous dominant (BB)
- You will have 50% heterozygous (Bb)
Now, for the phenotype, you will have 100% black fur, since B is dominant and is prevalent in 100% of all the breeds.
For the genotype, you have 50% BB and 50% Bb
