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.

homozygous recessive
Why is it important for scientists to be able to remove DNA from and organism?
It's important for scientists to be able to remove DNA from an organism because it'll help scientists identify genetic disorders or diseases.
Is it true that tissues are groups of similar cells that perform a specific function in an organism?
True.
What is tissue in a living organism?
a group of similar cells that perform a common function
What is basal dilation?
Basal dilation is when you perform dilation on an organism while it is at basal level. That is when its level of activity is low.
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!
When trying to find an unknown genotype you must perform a?
Perform a test cross. Cross the organism with an organism with a homozygous recessive genotype and use the phenotypes of the offspring and a Punnett square to figure out the unknown genotype.
What cross should a scientist perform in order to determine if the organism is heterozygous or homozygous dominant?
Scientists use a test cross to determine if an organism is heterozygous or homozygous dominant.
Why is it important for scientists to be able to remove DNA from and organism?
It's important for scientists to be able to remove DNA from an organism because it'll help scientists identify genetic disorders or diseases.
What do scientists perform to collect data?
Scientists perform experiments to collect data.
Where do scientists perform their work?
In a laboratory.
Can a one-celled organism perform all the activities of a multicelled organism?
Yes
