When performing a Testcross with the unknown genotype one can distinguish quizlet?

The ratio of the genotypes that appear in offspring is called the genotypic ratio. (1 BB : 2 Bb : 1 bb.) You could perform a testcross, in which an individual of unknown genotype is crossed with a homozygous recessive individual. One allele was completely dominant over another, a relationship called complete dominance.

What does a test cross determine?

A test cross is a way to explore the genotpye of an organism. Early use of the test cross was as an experimental mating test used to determine what alleles are present in the genotype. … Consequently, a test cross can help determine whether a dominant phenotype is homozygous or heterozygous for a specific allele.

How can you determine an unknown genotype of a tall plant?

We can determine the genotype of the plant by observing the phenotypes of the offsprings resulting from test cross.
