A punnet square uses letters to represent dominant and recessive alleles.
I am pretty sure the recessive and dominant alleles you are talking about are covered in Biology. Recessive alleles are basically alleles that are received from both parent's DNA that are carries, (dd). However, dominant alleles are (exactly what it says) always expressed. If there is one dominant allele and one recessive allele the dominant allele overpowers the recessive. (DD) and (Dd)overpowers (dd).
homozygous dominant means two alleles that are the same that are capital letters, heterozygous recessive means that to alleles are different BUT the same letters in lower case. (alleles for gender) EX: TT, Tt is homozygous dominant tt, tt is heterozgous recessive
Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.
In genetics, BB represents a homozygous dominant genotype, where both alleles are dominant. Bb represents a heterozygous genotype, where one allele is dominant and one is recessive. bb represents a homozygous recessive genotype, where both alleles are recessive.
Dominant alleles :-)
capital letters, such as PP equals two dominant alleles, pp equals two recessive alleles.
Yes, geneticists use letters to represent alleles of organisms. Typically, uppercase letters are used to represent dominant alleles, and lowercase letters are used to represent recessive alleles. For example, "A" may represent a dominant allele and "a" a recessive allele for a specific gene.
Alleles can be dominant or recessive
heterozygous recessive

Alleles can be either dominant or recessive. They can be identical or different for any given gene in a somatic cell, and can represent alternative forms of a gene.
In genetics, homozygous means having two of the same allele whether it be two dominant alleles or two recessive alleles.
homozygous dominant means two alleles that are the same that are capital letters, heterozygous recessive means that to alleles are different BUT the same letters in lower case. (alleles for gender) EX: TT, Tt is homozygous dominant tt, tt is heterozgous recessive
"Heterozygous" and "homozygous" are terms that refer to alleles, which, in genetics determine what trait, from which parent, will appear in the offspring. Alleles can be either Dominant or Recessive. Every organism has two alleles, which can both be dominant, both recessive, or one of each.So,If an organism heterozygous, it has one recessive and one dominant allele.If an organism is homozygous then both of its alleles are the same; you need to specify if they are homozygous recessive (both alleles are recessive) or homozygous dominant (both alleles are dominant).
Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.
Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.
A gene pair that consists of 2 dominant or 2 recessive alleles is considered homozygous dominant or homozygous recessive.
