In genetics, capital letters typically represent dominant alleles of a gene. For example, in a gene with two alleles, one dominant (represented by a capital letter, such as "A") and one recessive (represented by a lowercase letter, such as "a"), the presence of at least one capital letter indicates that the dominant trait will be expressed in the organism's phenotype. In contrast, lowercase letters represent recessive alleles, which are only expressed when two copies are present.
Recessive
a pair of recessive genes
A dominant gene is always expressed in an individual's phenotype when present, while a recessive gene is masked by a dominant gene and only expressed when two copies are present. Dominant genes are represented by capital letters (e.g., A), while recessive genes are represented by lowercase letters (e.g., a) in genetic notation.
Most are represented by two letters. It would be impossible for most to be represented by one letter as there are more than twice as many elements as there are letters.
Dominant alleles are written in upper case (i.e, 'A'), while recessive alleles are lower case (i.e, 'a')
capital genes are dominant genes as they are written by capital letters
Angles are represented by capital letters. Small letters refer to sides.

In the English alphabet, there are 26 letters. Each letter has a capital and a lowercase form, resulting in 52 distinct forms. Therefore, the fraction of the alphabet represented by capital letters (26) is equal to the fraction represented by lowercase letters (also 26), making them equal. Thus, neither fraction is greater; they are both equal at 1/2 of the alphabet.
nitrogen is an element.It is represented by N (only in capital letters).
Recessive
In a punnet square it is usually represented by a capital letter.
Dominant traits are represented as capital letters (D, R, H, J, etc) and recessive traits are represented as lower case letters (d, r, h, j, etc)

No, dominate traits do not have capital letters. The term "dominant traits" refers to the phenotype that is expressed when an individual has one dominant allele for a particular trait. It is not capitalized unless at the start of a sentence.
You decide that. All you have to do is define them before you start. The dominant gene is denoted by a capital letter, the recessive one by a lower case letter. It is better to pick a letter which has different forms for the capital and lower case letters (like A and a; not S and s).
