It doesn't need to be a triplet (3 letter) code rather than a quadruplet (4 letter), but a triplet code is more efficient as it means the genome can be shorter. There are only 20 amino acids used in protein translation and there are 64 different possible codons with three letters (more than enough), so four letters would be unnecessary.

What gene is always expressed?

Does a recessive allele need another recessive allele to be expressed?
Yes, a recessive allele needs to be paired with another recessive allele in order to be expressed. This is because recessive alleles are only expressed when an individual has two copies of the recessive allele, one from each parent. If an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele will be expressed.
Why are the rainfall measurement expressed in terms of depth and not volume?
Rainfall is expressed in terms of depth (in inches or millimeters) rather than volume (in liters or gallons) because depth measurement provides a more standardized and comparable way to quantify the amount of rain that falls across different locations and time periods. It allows for easier comparison and analysis of rainfall data without the need to account for variations in surface area or other factors that volume measurement would entail.
Can a individual carry a gene that is not expressed?
not usually, most books fit into the normal genres: mystery, fiction, nonfiction, adventure etc. I believe this person is referring to "genes," not "genres." To answer the question, then: yes, you can have genes that are not expressed. Recessive genes, for example, will not be expressed in heterozygous individuals; they will only be expressed in homozygous recessive individuals. For example; if you have the genotype Aa, the recessive gene - "a" - will not be expressed because the genotype contains a dominant allele, and the dominant allele will always be the one expressed. The only way that the "a" allele will be expressed is, again, if you are homozygous for that recessive gene (your genotype would be aa).
