Having two different alleles for a trait is called heterozygous.
alleles
The different forms of a genes for a single trait are known as alleles there can be a dominate allele which always shows up when present and a recessive allele which only shows up when both alleles are recessive or there is no dominate allele
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 has two alleles for one trait. If the two alleles are the same, the individual is homozygous for that trait, and if they are different, the individual is heterozygous.
When the alleles present for a trait are the same, it is called Homozygous
if the two alleles are the same in the same box in the punnett square then that trait is expressed. when there is a double in a punnett square then that gene is always expressed
An organism that possesses two different alleles for a trait is said to be heterozygous for that trait.
Having two different alleles for a trait is called heterozygous.
The trait could show up in two different forms. Alleles are individual units that determine what trait will be expressed in an offspring. Alleles exist for most traits such as hair color or wing size. Having two alleles simply means that the trait can be expressed in different variation. One trait can have several different alleles.
When there are multiple alleles present for a trait a variety of phenotypical outcomes is possible. These traits can be dominant, recessive, co-dominant, or incompletely dominant.
