What letters are used to represent a homozygous?

Two of the same letter. For example, if you have a homozygous organism for dominant red color, then the letters to represent their genotype would be RR. However, if the red color is a recessive trait, then a homozygous organism with that trait will have the genotype rr.


What do the letters along the top and the bottom of the punnett square represent?

The letters to the left are the two alleles (the genotype) of one parent and the letters above is the other parents genotype. If the letter is capital it means the trait is dominant and if the letter is lowercase, it's recessive


A plant with the genotype TT is called?

Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.


What represents heterozygous A?

To represent a heterozygous genotype, you would you two DIFFERENT letters. Whether it would be lower case or upper case depends on if it's dominant or not.


How can one effectively write a genotype in a scientific report or research paper?

When writing a genotype in a scientific report or research paper, it is important to use the correct format. This typically involves using the specific letters that represent the alleles for a particular gene. For example, if discussing a gene with two alleles, one dominant and one recessive, you would write the genotype as two letters, with the dominant allele capitalized and the recessive allele lowercase. It is also important to provide context and explain the significance of the genotype within the study.


Is the genotype for free earlobes reprented with two capital letters or two lowercase letters?

one capital letter and one lowercase letter


What type allele are present in an organism with a QQ genotype?

Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.


What are the homozygous letters of a tall parent?

Uhh.. theoretically, if you were to represent a tall parent's genotype they would be something like TT, but it's much more complicated than that. Height is a multifactorial polygenic trait that can't be expressed as a single genotype, practically.


What is one or two letters called that represent an element?

The chemical symbol is one or two letters that represent an element.


Which is a heterozygous or hydrid genotype?

A heterozygous genotype consists of a dominant gene and a recessive gene. Homozygous genotypes consist of two dominant genes (Homozygous Dominant) ro two recessive genes (Homozygous Recessive).Heterozygous: XxHomozygous: Dom. XXRec. xx


How do you write the genotype for a trait?

Genotypes are written differently depending on what gene you are referring to. A capital letter means that allele is dominant over an allele written with a lower case letter. For example B is dominant over b. Some genotypes are written using a superscript, such as IAIB for the genotype of a person with blood type AB. Or HbsHbs for a person with sickle cell anaemia (compared to HbSHbS for a person without sickle cell). In this case Hb stands for haemoglobin. Usually the letters chosen relate to the trait involved... for example, if talking about tall plants T would be used to represent the tall allele and t would represent the short allele.


Why are genotypes written with two letters?

Because a genotype is symbology for the actual alleles of a particular gene. Since all genes come in pairs (on the 22 pairs of body chromosomes), one from each chromosome. Examples: BB Bb or bb . Usually capital letters are used to describe dominant alleles and lower case for recessive alleles.
