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.

An individual who is homozygous is what?
It is a genetic similarity between two organisms.
Condition of being heterozygous for a recessive trait?
If you are heterozygous this means you carry both a dominant and recessive allele. if you are heterozygous for a recessive trait then you will have a dominant and recessive allele. example: let T represent tall and t represent short. a person with heterozygous for a recessive trait will have 'Tt'.
Why is a son who receives the allele for color blindness from his mother always colorblind?
Color blindness is a sex-linked trait that is carried on the X chromosome. Since males inherit their single X chromosome from their mother, if the mother carries the allele for color blindness, her son will inherit it and be colorblind. Females need two copies of the allele to be colorblind, so they can be carriers without exhibiting the trait.
Describe the principles of dominance segregation and independent assortment based on Mendel's experiments?
The law of dominance states that one trait has domination over another trait unless they are both recessive genes. The law of segregation states that two copies of the genes separate and the offspring has one factor from each of the copies. The law of independent assortment states that the law of chance chooses which traits an offspring will gain based off of its parents traits.
What is hom and het?
Hom and het are abbreviations commonly used in genetics to refer to genotypes. "Hom" stands for homozygous, indicating that an individual has two identical alleles for a particular gene. "Het" stands for heterozygous, indicating that an individual has two different alleles for a particular gene.
What oranism has two different alleles for a trait?
An organism that possesses two different alleles for a trait is said to be heterozygous for that trait.
When a pair of chromosomes contains different alleles for a trait that trait is called a what when a trait has two identical alleles it is called?
2 different alelles - heterozygous Same alelles - homozygous
What is a organism that has two different allels for a trait?
an organism that has two different alleles for a trait is heterozygous
Organism that has two diffrent alleles for a single trait?
An organism that has two different alleles for a single trait is called heterozygous. This means that the organism inherited different versions of the gene responsible for that trait from each parent.
Organisms that has two different alleles for a trait?
An organism with two different alleles for a trait is said to be heterozygous for that trait. This means that it has one dominant allele and one recessive allele. The dominant allele will usually determine the organism's phenotype for that trait.
What has two identical alleles for a trait?
Homozygous individuals have two identical alleles for a specific trait. This means they can be either homozygous dominant (two dominant alleles) or homozygous recessive (two recessive alleles). Homozygosity results in the expression of either the dominant or recessive trait.
How many alleles for one trait are normally found in the genotype of an organism?
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.
Organisms with two different alleles for a trait?
The organism that has two different alleles for the same trait is called heterozygous. This also refers to a cell or an individual that has two different forms of gene.
Which term means the state of having two different alleles for the same trait?
Two different alleles for the same trait are heterozygous. No, Its homozygous. This answer is incorrect as homo = same.
What are two different alleleles for a trait called?
Different alleles for a trait are known as gene variants. For example, two different alleles for the gene that determines flower color in pea plants are purple (P) and white (p). When an individual has two different alleles for a trait, it is known as heterozygous.
What does it mean if there are 2 different alleles for a trait?
A Trait Could Show Up In Two Different Forms
An organism that has two different for a trait is heterozygous?
alleles
