An organism that has two identical alleles (like two capitol “T’s” or two lowercase “t’s” for example) is called
TT would be a dominant Allele. tt would be a Recessive Allele. Example: Blue eyes are recessive Bb so if one parent has blue eyes and the other has brown eyes brown would be dominant BB. So you would most likely have brown eyes BB. Unless both parents have blue eyes then you would most likely also have blue eyes bb.
bb is blue. BB is brown. Bb is also brown.

An organism that has two identical alleles (like two capitol “T’s” or two lowercase “t’s” for example) is called ________________(homozygous or heterozygous)
homozygous I think. If you don't believe me look up the definition of both words.
An organism that has two identical alleles is called a homozygote. It can be homozygous dominant (TT) or homozygous recessive (tt), depending on whether the alleles are dominant or recessive.
To determine if an organism is homozygous, you need to examine its genotype, which refers to the specific combination of alleles it carries for a particular trait.
To find out if an organism is a homozygote:
1. Identify the trait you are interested in and the alleles associated with it. For example, let's consider the trait for flower color, where the dominant allele (T) results in purple flowers, and the recessive allele (t) results in white flowers.
2. Observe the organism's genetic makeup or genotype. This can be done through genetic testing or by analyzing the characteristics passed down from parents. Let's say we are examining an organism with purple flowers, and its genotype is TT.
3. Determine if the organism has two identical alleles. In this case, the organism's genotype is TT, indicating that it has two identical dominant alleles. Therefore, it is a homozygote.
On the other hand, if the genotype were Tt, it would be a heterozygote because it has two different alleles (one dominant and one recessive) for the trait.
Remember that the term homozygote applies to any organism that has two identical alleles, whether those alleles are recessive or dominant.
