|Heterozygous||One dominant allele and one recessive allele||Tt|
|Homozygous dominant||Two dominant alleles||TT|
What is the genotype TT an example of?
If the two alleles are the same (TT or tt), the genotype is considered purebred. If the two alleles are different (Tt), the genotype is considered hybrid. This example shows the inheritance of a single characteristic (height). A cross that shows the inheritance of a single characteristic is known as a monohybrid cross.
What is your genotype if you are heterozygous?
An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb. Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb.
Is TT a hybrid?
The petrol-powered Audi TT – first introduced in 1998 – will be replaced with an electric sports car in a few years’ time, company chairman Bram Schot has said. … As such, both plug-in hybrid and fully-electric TTs are under consideration.
What is an example of heterozygous?
Your genes are made of DNA. … If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair.
What does genotype TT mean?
The genotype is represented by letter combinations, such as TT, Tt, and tt. When an organism has two of the same alleles for a specific gene, it is homozygous (homo means “same”) for that gene. … If an organism has two different alleles (Tt) for a certain gene, it is known as heterozygous (hetero means different).
Which allele is always written first?
The alleles are represented by letters. The letter chosen is usually the first letter of the trait.
