One of the factors that promote invasiveness in exotic species is if<u> such species lack natural predators or competitors</u>. In other words, <u>the invasiveness of a nonnative species can be promoted when they occupy a previously unoccupied niche, resulting in a lack of competition. </u>The presence of a competitor will either results in <u>a competitive exclusion</u> that might not favor the newly introduced species or <u>resource partitioning</u> that sort of limits their growth.
Hence, in the case of the nonnative fish introduced into a lake, sharing a niche with another species can prevent it from becoming an invasive species.

Assuming both parents have genotype Bb, this would lead to the Punnett square (in this case a monohybrid cross) as shown in the image below. We have four outcomes, three of which are unique. Those offspring genotypes are: BB, Bb, and bb.
An offspring with B or b on its own is not possible because both parents contribute genes.
