capital letter
A capital letter in a phenotype typically stands for the dominant allele or trait. This means that if an organism has at least one copy of the dominant allele, the corresponding trait will be expressed.

In genetics, "l" in the FOIL method stands for "last." The FOIL method is a mnemonic used primarily for binomial multiplication, which stands for First, Outside, Inside, and Last. In the context of genetics, it's often used to help remember how to combine alleles from two parents when analyzing genetic crosses, particularly in Punnett squares.
It stands for square kilometre which is a unit if measure of area. 1 sq km = 1 million square metres.
That is called an acronym poem, where each letter in the poem represents a word or phrase.
Capital letters on Punnett Squares represent dominant genes, while lowercase letters represent recessive genes. For example, if the trait "T" is a tall gene and the trait "t" is a short gene. When you get your results (if both parents are heterozygous for tallness, Tt) you get four possible results, 1 TT (homozygous tall), 2 Tt (twice, heterozygous tall Tt), and 1 tt (homozygous short). If there is a dominant gene there, that gene will be displayed. Only if there are two recessive genes will the recessive trait be displayed.
a CAPITAL letter
A punnett square looks like this. Lets say that you had 2 flowers, and you wanted to find the likelihood that their offspring would be purple. Purple is dominant over white. You have one pure purple plant, (PP), and one hybrid purple plant, (Pp). The big P stands for purple, and the little p stands for white. You take the PP and put it on the top, one P over each of the top squares. Then you take the Pp and put each p on one of the side squares. You take one letter from each part of the square, so your four possibilities would be PP, PP, Pp, and Pp. There is no way that the plant could be white.
A small letter stands for a recessive allele.
A capital letter in a phenotype typically stands for the dominant allele or trait. This means that if an organism has at least one copy of the dominant allele, the corresponding trait will be expressed.
a recessive allele is shown using a lower case letter a dominant allele is shown using a capital letter
recessive
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.
A capital letter in a punnet square stands for a domminant trait, or one that will most likely appear. --Stew Pidacel
Physicality stands out as his dominant trait
It's impossible to say without more information. The genotype AA is called homozygous dominant for the trait that is encoded by the letter A (or a). Whatever trait A stands for on your homework, the answer is the dominant one is expressed in the phenotype.
Circle stands for female and square stands for male.
