That depends on the gene: some genes have only a few alleles, some genes have hundreds or even thousands of alleles.
Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.
an organism that has two different alleles for a trait is heterozygous
Hybrid
In the study of genetics, we often refer to things call Alleles. These things can help us work out the chance of a particular person having a particular characteristic.In genetics we call lower case letters recessive alleles, for example 't'However, alleles always come in pairs, one from the mother, one from the father so it would be tt.I don't want to over complicate things but there are also dominant alleles which are shown as upper case letters, so 'T'.tt is basically the recessive genotype of a particular characteristic.We call the two alleles together a genotype.Hope this helps!
The answer to your question, "What is an organism with 2 of the same alleles for a trait called?" is homozygous. it is just homozygous-By SciienceFreak
We call these genes the genome.
Genotype
You're looking at a gene which contains 2 alleles (meaning variations of that gene). Let's call it "A."Remember that you get 2 copies of EACH gene (one from mom, one from dad).
alleles.
When an allele creates a visible trait, it is called a dominant allele. Dominant alleles mask the expression of recessive alleles when present in a heterozygous individual.
genotype
Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.
Codominace
Homozygous recessive.
an organism that has two different alleles for a trait is heterozygous
The different forms of a gene are called alleles.
