One can determine whether a genotype is heterozygous or homozygous by looking at the alleles present. If there are two different alleles for a particular gene, the genotype is heterozygous. If there are two of the same alleles, the genotype is homozygous.

To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is?
To determine the genotype of an individual showing the dominant phenotype, you would cross it with a homozygous recessive individual. This would help reveal whether the dominant phenotype individual is homozygous dominant or heterozygous for the trait.
What is the procedure in witch an individual of unknown genotype is crossed with a homozygous recessive individual to determine the genotype of the unknown individual is called?
This procedure is called a test cross. By crossing an individual of unknown genotype with a homozygous recessive individual and analyzing the offspring, geneticists can determine whether the unknown individual is homozygous dominant or heterozygous for a particular trait.
Which is a heterozygous or hydrid genotype?
A heterozygous genotype consists of a dominant gene and a recessive gene. Homozygous genotypes consist of two dominant genes (Homozygous Dominant) ro two recessive genes (Homozygous Recessive).Heterozygous: XxHomozygous: Dom. XXRec. xx
How can one determine whether an individual is homozygous or heterozygous using gel electrophoresis?
In gel electrophoresis, an individual can be determined to be homozygous or heterozygous by looking at the number and size of bands on the gel. Homozygous individuals will show only one band, while heterozygous individuals will show two bands of different sizes.
Diffrence between homozygous and heterozygous?
Homozygous refers to having two identical alleles for a particular gene, while heterozygous means having two different alleles for the same gene. In homozygous individuals, both alleles are either dominant or recessive, while in heterozygous individuals, one allele is dominant and the other is recessive.

To determine the genotype of an individual showing the dominant phenotype, you would cross it with a homozygous recessive individual. This would help reveal whether the dominant phenotype individual is homozygous dominant or heterozygous for the trait.

Is it easier to analyze genotype by observing phenotype in organisms with complete dominance or in organisms with incomplete dominance?
It is generally easier to analyze genotype by observing phenotype in organisms with complete dominance because the phenotypic expression directly reflects the genotype. In contrast, with incomplete dominance, the phenotype is an intermediate between the two homozygous genotypes, making it more challenging to accurately determine the genotype solely based on the phenotype.
Which is a heterozygous or hydrid genotype?
A heterozygous genotype consists of a dominant gene and a recessive gene. Homozygous genotypes consist of two dominant genes (Homozygous Dominant) ro two recessive genes (Homozygous Recessive).Heterozygous: XxHomozygous: Dom. XXRec. xx

How is a genetic test cross helpful?
A genetic test cross is helpful in determining the genotype of an individual with unknown genotype by crossing it with a homozygous recessive individual. This allows the alleles to separate and be observed in the offspring, providing information on the genotype of the individual being tested.
Is AA an homozygous or an heterozygous?
AA could be either homozygous or heterozygous, depending on whether the individual inherited the same allele (A) from both parents (homozygous) or different alleles (Aa) from each parent (heterozygous).
Is Ee a heterzygous or homozygous?
Based on the information provided, it is not clear whether "Ee" refers to a specific gene or trait. In genetics, "Ee" could represent a heterozygous genotype for a particular gene if one allele is dominant and the other is recessive. Alternatively, if "Ee" represents a homozygous genotype where both alleles are the same (homozygous dominant or homozygous recessive), it would depend on the specific context of the gene or trait.
Diffrence between homozygous and heterozygous?
Homozygous refers to having two identical alleles for a particular gene, while heterozygous means having two different alleles for the same gene. In homozygous individuals, both alleles are either dominant or recessive, while in heterozygous individuals, one allele is dominant and the other is recessive.
If you are Rh plus can you know your genotype for sure?
Knowing your blood type (Rh positive or negative) does not determine your genotype with 100% certainty. Specific genotyping tests are needed to determine the exact genetic makeup of the Rh factor (e.g., whether you are RhD positive or negative) in addition to your ABO blood type.
In pea plants inflated pods are dominant to constricted pods what crosses is a test cross?
A test cross would involve crossing a pea plant with a constricted pod (to determine its genotype) with a homozygous recessive plant (constricted pod), as this cross would reveal whether the first plant is heterozygous or homozygous dominant for the trait of pod shape.
How could the botanist best determine whether the genotype of the green-pod plant is homozygous or heterozygous?
The botanist could perform test crosses between the green-pod plant and a known homozygous recessive individual. If all offspring show the dominant green pod trait, the green-pod plant is likely homozygous. If the offspring display a mix of green and yellow pods, the green-pod plant is most likely heterozygous.
