∙ 11y agoTo determine if a particular plant is homozygous or heterozygous, you would need to perform a test cross with a homozygous recessive individual. If the offspring display the recessive trait, the original plant would likely be heterozygous. If all offspring exhibit the dominant trait, the original plant would likely be homozygous dominant.
To determine if a plant is homozygous or heterozygous, you would need to test cross it with a homozygous recessive plant. If the offspring show the recessive trait, the original plant is heterozygous; if all offspring show the dominant trait, the original plant is homozygous.
The scientist should perform a test cross between the organism and a homozygous recessive organism. If all offspring show the dominant trait, the original organism is homozygous dominant. If some offspring show the recessive trait, the original organism is heterozygous.
To determine the genotype of an individual who is heterozygous for a trait, you would need to perform a genetic cross with a homozygous recessive individual. By observing the phenotypes of the offspring, you can deduce the genotype of the heterozygous individual. This can help determine if the heterozygous individual is carrying one dominant and one recessive allele.
To perform a testcross, you cross an individual with a dominant phenotype (but unknown genotype) with a homozygous recessive individual. By examining the offspring's phenotypes, you can determine the genotype of the unknown individual through the principles of Mendelian genetics. This allows you to determine if the individual is homozygous dominant or heterozygous for a specific trait.
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.
To determine if a plant is homozygous or heterozygous, you would need to test cross it with a homozygous recessive plant. If the offspring show the recessive trait, the original plant is heterozygous; if all offspring show the dominant trait, the original plant is homozygous.

A testcross is a genetic cross between an individual with an unknown genotype and a homozygous recessive individual to determine the unknown genotype. This cross helps determine if the individual with the unknown genotype is heterozygous or homozygous for a particular trait.
A cross between two individuals that are homozygous for different alleles will only produce heterozygous offspring. This is because each parent can only donate one type of allele, resulting in all offspring being heterozygous for that particular gene.
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.
In a dihybrid cross, the expected genotypic ratio is 1:2:1 for homozygous dominant: heterozygous: homozygous recessive genotypes, respectively. In a monohybrid cross, the expected genotypic ratio is 1:2:1 for homozygous dominant: heterozygous: homozygous recessive genotypes, respectively.
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.
A test cross between a homozygous recessive and a heterozygous individual will yield 50% of offspring as homozygous recessive. This is because all the offspring will inherit one recessive allele from the homozygous recessive parent.
To determine the genotype of an individual who is heterozygous for a trait, you would need to perform a genetic cross with a homozygous recessive individual. By observing the phenotypes of the offspring, you can deduce the genotype of the heterozygous individual. This can help determine if the heterozygous individual is carrying one dominant and one recessive allele.
A cross between a homozygous recessive and an individual of unknown genotype is called a test cross.The homozygous recessive can only pass on a recessive allele to the offspring, and so any recessive in the other parent will show up in the phenotype (detectable characteristics) of some of the offspring.
To perform a testcross, you cross an individual with a dominant phenotype (but unknown genotype) with a homozygous recessive individual. By examining the offspring's phenotypes, you can determine the genotype of the unknown individual through the principles of Mendelian genetics. This allows you to determine if the individual is homozygous dominant or heterozygous for a specific trait.
The homozygous recessive individual is used in a test cross to determine the genotype of an individual with a dominant phenotype but unknown genotype. When crossed with a homozygous recessive individual, if any offspring display the recessive trait, it indicates that the unknown individual is heterozygous for that trait.
