If you're talking about a Pedigree tree, the circle or square is only half coloured in (it will be white on one side and black on the other)
If you're talking about symbols for a Punnett square, usually it's a capital letter followed by the un-capitalized version of the same letter (for example, Hh, or Gg)
A heterozygous allele combination is typically shown using letters to represent the alleles of a gene. For example, if the alleles for a gene are "A" and "a," a heterozygous individual would be represented as "Aa." This signifies that the individual has one copy of each allele.
Alleles are represented as: Gg Where G is the dominant trait and g is the recessive trait Therefore, homozygous dominant would be: GG Homozygous recessive would be: gg and heterozygous would be Gg
In a punnet square it is usually represented by a capital letter.
The individual with two of the same allele is "homozygous" for a trait.
The allele pair of someone with a genotype TT is homozygous dominant.

homozygous
A synonym for homozygous recessive is "homozygous for a recessive trait." This term refers to an individual who has two identical recessive alleles for a particular gene. In genetic notation, it is often represented as "aa," where "a" signifies the recessive allele.
The individual with two of the same allele is "homozygous" for a trait.
lowercase allele
The allele pair of someone with a genotype TT is homozygous dominant.
They will produce gametes that are also homozygous.
Homozygous is the term used to describe an organism with two allele pairs that are identical, in reference to dominant characteristic traitÊin heredity.
homozygous
A homozygous recessive individual (ss) carries two copies of the recessive allele and does not possess a dominant allele. Therefore, when this individual produces gametes, all gametes will carry only the recessive allele (s). Consequently, the probability of a homozygous recessive individual producing a gamete with a dominant allele is 0%.
