Knockout mice

... gene. The mouse will likely produce the protein from the wild-type copy of the gene, but depending on how the gene is regulated it is likely that expression of the protein will be below wild-type levels.

How dominance works at the DNA/RNA/protein

... together, so you do cross-pollination. Your new generation receives one copy of each chromosome from yellow pea plant and one copy of each chromosome ... subtle way or drastically on the DNA level – the main difference is in expression. That can be due to different transcription efficiencies (mRNA), ...
