What is the difference between homozygous and herterozygous?
Homozygous refers to having two identical alleles for a particular gene, while heterozygous means having two different alleles for the same gene. Homozygous individuals can be either homozygous dominant (two dominant alleles) or homozygous recessive (two recessive alleles), while heterozygous individuals have one dominant and one recessive allele.
What letters are used to represent a homozygous?
Two of the same letter. For example, if you have a homozygous organism for dominant red color, then the letters to represent their genotype would be RR. However, if the red color is a recessive trait, then a homozygous organism with that trait will have the genotype rr.
What is a Genotype in which both alleles are the same?
A genotype in which both alleles are the same is called homozygous. This means that the individual has two identical alleles for a particular gene (e.g., AA or aa). Homozygous genotypes can be either homozygous dominant (both alleles are dominant) or homozygous recessive (both alleles are recessive).
Organism possessing two identical genes for a trait is said to be?
An organism that has two different alleles of the same gene is a heterozygous organism. Due to the various effects of different alleles, an organism's traits do not reveal its genetic composition.
Differentiate between homozygous and heterozygous?
Homozygous refers to having two identical alleles of a particular gene, while heterozygous refers to having two different alleles of a particular gene. In homozygous individuals, both alleles are the same (e.g., AA or aa), while in heterozygous individuals, the alleles are different (e.g., Aa).
What type of alleles are presented in a homozygous genotype?
homozygous(different gene)-Rr heterozygous(same gene)-RR,rr
If a homozygous dominant parent and a heterozygous parent are crossed what percentage of the offspring are expected to be homozygous dominant?
Rr
What is the difference between homozygous and herterozygous?

Homozygous individuals can be either homozygous dominant (two dominant alleles) or homozygous recessive (two recessive alleles), while heterozygous individuals have one dominant and one recessive allele.
If R is dominant to r the offspring of the cross of RR with rr will be homozygous?
R R r Rr Rr r Rr Rr That is the Punnet Square. The genotype will be 100% Rr in the cross. The phenotype will be whatever phenotype is constituted by your dominant allele.
What letters are used to represent a homozygous?
Two of the same letter. For example, if you have a homozygous organism for dominant red color, then the letters to represent their genotype would be RR. However, if the red color is a recessive trait, then a homozygous organism with that trait will have the genotype rr.
A genotype consisting of two identical alleles of a gene for a particle trait?
A genotype consisting of two identical alleles of a gene for a particular trait is called homozygous. This means that both alleles are the same, which can either be dominant or recessive. Homozygous genotypes can result in the expression of a specific trait depending on the alleles involved.
What are the possible genotypes if you do a punnett square with one parent who is Homozygous dominant RR for being resistant to poison ivy and one parent who is allergic to poison ivy rr?
RR X rr 100% Rr Heterozygous resistant for poison ivy.
What is a Genotype in which both alleles are the same?
A genotype in which both alleles are the same is called homozygous. This means that the individual has two identical alleles for a particular gene (e.g., AA or aa). Homozygous genotypes can be either homozygous dominant (both alleles are dominant) or homozygous recessive (both alleles are recessive).
What is the genotype of a person that is homozygous non sicklier?
The genotype of a person who is homozygous non-sickler for sickle cell anemia would be HbAHbA, meaning they have two normal hemoglobin genes. This genotype does not carry the mutation that causes sickle cell anemia.
What is the difference fom heterozygous and homozygous recessive?
In genetics, you can either have a dominant allele (A) or a recessive allele (a). Being homozygous means that you have both of either a dominant or a recessive allele (ie you are either AA or aa). If the trait is a recessive trait, then you need to have it be homozygous recessive in order to express that trait. Hope this was helpful! :-)
A pea plant with round seeds has the genotype Rr you cross this plant with a wrinkled seed plant genotype rr what is the probability that the offspring will have wrinkled seeds?
To figure this out, use a Punnet Square.First, set up a test cross, like this:Rr x rrThis shows what you are crossing. Now you can make a Punnet Square.R rr Rr rr There is a 50/50 chance that the corn plant will have thegenotype rr.r Rr rr
