How are homozygous and heterozygous allele combinations for a particular trait in plants different?
A homozygous trait is expressed when 2 of the same alleles make up the genotype. For example, if two alleles (A and a) were present, the homozygous trait would be either AA or aa. In general, a fully recessive trait is only expressed when it's homozygous.
What are organisms that have two different alleles?
When you have two identical alleles you are said to be homozygous for that particular trait. If the trait is dominant, then you are homozygous dominant. If the trait is recessive, then you are homozygous recessive.
How do you identify a homozygous ressive genotype?
See if the parent organisms have the same trait as the offspring. Those traits have to be recessive.
A genotype consisting of two identical alleles of a gene for a particle trait?
it is a homozygous or heterozygous ( RR or rr)
How do you prove if something is heterozygous?
The carrier must be Homozygous because if he were hetero it must be Hh and the dominant gene is expressed but homozygous gives them the possibility of hh (only a carrier) or HH (definitely a carrier) Don't totally understand the previous answer; however, I understand the question to mean that you want to know if you are homozygous or heterozygous for a certain trait. If you express a recessive phenotype, that is you have blue eyes for example, you are definitely homozygous for that trait. If one of your parents has a recessive trait, like blue eyes, and the other parent expresses a dominant trait, like brown eyes, AND if you have brown eyes, you can be sure that you are heterozygous. Otherwise it is impossible to tell until you have children. Then you can work backwards from you and your spouse, look at their parents and your parents and then figure the only possible way all those conditions could exist is if you are heterozygous or if you are homozygous for that trait.
Organisms with two identical alleles for a specific trait are what?
homozygous
Organism that have two identical alleles for a particular trait are said to be?
Organisms that have two identical alleles for a particular trait are said to be? homozygous
What does it mean to be homozygous dominant heterozygous or homozygous recessive?
Homozygous means "same" so a homozygous recessive trait would be a same [with parents] trait that is not the stronger trait which is dominant. Dominant is stronger showing trait, recessive is weaker trait. If you are dealing with Punnett squares then tt is homozygous recessive and TT is homozygous dominant. Hope this helped...
What does it mean to be homozygous for a trait?
both chromosomes from your parents are the same
An individual with two identical alleles of a gene is?
An organism that has two identical alleles for a trait is known as a homozygote or a homozygous organism.
How are homozygous and heterozygous allele combinations for a particular trait in plants different?
A homozygous trait is expressed when 2 of the same alleles make up the genotype. For example, if two alleles (A and a) were present, the homozygous trait would be either AA or aa. In general, a fully recessive trait is only expressed when it's homozygous.
What are organisms that have two different alleles?
When you have two identical alleles you are said to be homozygous for that particular trait. If the trait is dominant, then you are homozygous dominant. If the trait is recessive, then you are homozygous recessive.
An organism that has two identical alleles for a trait?
Are known as homozygous. Homozygous individuals can also be called 'purebred'. Organisms with two different alleles are known as heterozygous.
Are homozygous true breeding for a particular trait?
yes. no matter whether they are homozygous dominant or recessive.
How can offspring inherit a recessive trait?
An offspring can inherit a recessive trait if both of its parents are homozygous for the dominant allele.
What is an allele that produce a trait in the heterozygous condition is?
homozygous
Describes organisms or genotypes that are homozygous for a specific trait and thus always produce offspring that have the same phenotype for that trait?
True-breeding
