What did Mendel use in his first experiment to test his hypothesis about genes?
testcross
How can you determine the genotype plant that displays the dominant form of a trait?
Do a testcross with a homozygous recessive plant.
How can you determine the genotype of a plant that displays the dominant form of trait?
Do a testcross with a homozygous recessive plant.
How can the farmer determine if his red tomatoes are pure or hybrid?
do a testcross. if they are pure, offsprings will be all red. if they are hybrids, half of the offsprings will be yellow.
Why does a cell perform fermentation if it does not produce any ATP energy for the cell?
Fermenation basically regenerate NAD+ from NADH, which is needed to produce more ATPs.
To perform a testcross scientists cross an organism with an unknown genotype with what kind of organism?
homozygous recessive
What perform a testcross on a tall pea plant. Half the offspring are short. What conclusion can you draw from this outcome?
The genotype of the tall pea plant is heterozygous!
A testcross determines what?
genotype
To perform a testcross scientists cross an organism with an unknown genotype with a organism.?
If an individual is of the dominant phenotype, its genotype can be either AA or Aa (letter A picked for demonstration's sake). To do a good test cross, we have to be able to unambiguously tell which one of the genotypes the individual is. The best test cross would be conducted with a homozygous recessive (aa) individual. This way, if the cross generates 100% dominant phenotype, then the original individual was homozygous dominant. If the cross generates 50% dominant and 50% recessive phenotype, then the original individual was heterozygous.
If all the offspring of a testcross are alike and resemble the organism being tested then is the parent homozygous?
If all the offspring of a testcross are alike and resemble the organism being tested then the parent is homozygous.

testcross
What equipment qould be needed to perform this experiment?
What equipment was needed for this experiment
In a testcross of a heterozygous tt unknown of the offspring would be Tt?
It would be around 50%.
