How is a dominant trait written?
A dominant allele is denoted by a capital letter (A versus a). Since each parent provides one allele, the possible combinations are: AA, Aa, and aa. Offspring whose genotype is either AA or Aa will have the dominant trait expressed phenotypically, while aa individuals express the recessive trait.
What is the symbol for a dominant gene?

What are dominant alleles represented by?
Dominant alleles are represented by capital letters and recessive alleles are represented by lowercase letters. For example, blue eyes are a recessive trait and brown eyes are a dominant trait.
How do you write dominant and recessive traits?
The way people write out dominant and recessive traits is the dominant one gets a capital letter and the recessive one a lower case letter. So for eye color, brown is B and blue is b. As I said above, people have two versions of each gene so you can be BB, Bb, or bb–BB and Bb have brown eyes, bb, blue eyes.

What do daughters inherit from fathers?
Girls get two X chromosomes, one from Mom and one from Dad. This means that your daughter will inherit X-linked genes from her father as well as her mother. When your daughter inevitably ends up with his X chromosome, does that mean she’ll inherit all of his X-linked genes and traits? Genes, yes.
What personality traits can you inherit from your parents?
Among the traits found most strongly determined by heredity were ambition, vulnerability to stress (neuroticism), leadership, risk-seeking, a sense of well-being and, surprisingly, respect for authority.
