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 that shows the dominant phenotype you would cross that individual with one that is homozygous recessive. A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance would probably result in a phenotype ratio is 3 dominant 1 recessive.
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?
They refer to the alleles in a genotype. For the basics of genetics, we can say that each allele is either dominant or recessive. Dominant is represented by an uppercase letter, and recessive a lowercase. If the genotype is AA, it is homozygous dominant. If it is aa it is homozygous recessive. If it is Aa, it is heterozygous. Simply, homozygous means that both of the alleles are the same and heterozygous means it has one of each allele.

Is it easier to analyze genotype by observing phenotype in organisms with complete dominance or in organisms with incomplete dominance?
It is easier to analyze genotype by observing phenotype in organisms with incomplete dominance (also known as codominance), because in incomplete dominance the individual will show a specific phenotype for each situation, whether it is homozygous dominant, heterozygous, or homozygous recessive. For example, in flowers, such as the ones that Mendel studied, a homozygous dominant flower will be red, a homozygous recessive flower will be white, and a heterozygous flower will be pink. In complete dominance, a heterozygous will only express the dominant phenotype, as opposed to incomplete dominance, in which a heterozygous individual will express a phenotype that is representative of both of the dominant and recessive traits. Because heterozygous individuals in complete dominance express the dominant phenotype, it is hard to determine whether the genotype is homozygous dominant or heterozygous for the trait. Hope this helps!

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).
When can you use a test cross?
A test cross is used to determine the genotype of an organism exhibiting a dominant phenotype. By crossing this organism with a homozygous recessive individual, the offspring's phenotypes reveal whether the dominant organism is homozygous or heterozygous. If any recessive phenotypes appear in the offspring, the dominant parent is heterozygous; if all offspring display the dominant phenotype, the parent is likely homozygous. This method is commonly employed in genetics to assess inheritance patterns.
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.

How could a boxer dog breeder determine whether a wire-hair boxer dog is homozygous or heterozygous for this trait?
A boxer dog breeder can determine whether a wire-hair boxer is homozygous or heterozygous for the wire-hair trait through genetic testing or by performing a breeding test. By breeding the wire-hair boxer with a known homozygous recessive dog (that exhibits the opposite coat type), the breeder can observe the offspring's traits. If all offspring display the wire-hair trait, the original dog is likely homozygous; if any offspring exhibit the other coat type, the original dog is heterozygous. Additionally, genetic testing can directly reveal the dog's genotype for the wire-hair trait.
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.
