Deoxyribonucleic acid otherwise known as DNA. traits are controlled by commonalities in DNA structure between two separate sequences
Genes
Acquired Trait
A genetic trait.
Heterozygous
two or more genes
That organism has two recessive alleles for that trait, one from each parent. It will display the recessive trait.
The traits an organism displays is a result of their genetics. Recessive traits tend to not show in many organisms.
An organism can have/carry a gene but without espressing this gene.
If the the trait is controlled by only one allele and the allele is completely dominant then once inherited the offspring with exhibit that phenotype
An organism with two like alleles for a trait is homozygous for that trait.
Non-Mendelian traits are:A trait with no clearly dominant alleleA trait with four allelesA trait controlled by many genes
A recessive trait is one that is not expressed when paired with a dominant trait. It may only be visually evident when both copies of the gene carry the recessive form.
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
an organism that has two different alleles for a trait is heterozygous
A trait controlled by many genes
A homozygous trait is controlled by only one kind of allele, while a heterozygous trait is controlled by multiple allele types.
A trait controlled by four alleles is said to have multiple alleles.
