The answer is "variable-ratio schedule".
In operant conditioning, a variable-ratio plan refers to a calendar of fortification where a reaction is strengthened after an eccentric number of reactions. This timetable makes an enduring, high rate of reacting. Betting and lottery diversions are great cases of a reward in view of a variable ratio schedule.

Concentrate on pronunciation. (Kun-TROLE group) In a medical control, the group that does not receive the new remedy is being studied. This organization is compared to the group that gets the new remedy, to see if the brand new remedy works.
A control organization in a scientific test is a set separated from the relaxation of the test, in which the unbiased variable being examined can not affect the effects. This isolates the independent variable's effects on the experiment and can help rule out opportunity factors of the experimental effects
In a systematic observation, a managed institution is used to set up a reason-and-impact relationship by using keeping apart the effect of an independent variable. Researchers change the independent variable inside the treatment institution and hold it regularly within the control group. Then they examine the results of those agencies.

Answer:
RrYy x RrYy
Explanation:
Given
Round (R) allele is dominant over wrinkled allele "r"
and Yellow seed allele (Y) is dominant over green seed allele "y"
If I find a plant with round and yellow seeds and want to determine its genotype, then I will cross it with plant that has heterozygous genotype for both the characteristics i.e "RrYy"
Let us say that the plant I found is heterozygous dominant for both the traits i.e "RrYy"
If RrYy is crossed with another RrYy ,we get -
RY Ry rY ry
RY RRYY RRYy RrYY RrYy
Ry RRYy RRyy RrYy Rryy
rY RrYY RrYy rrYY rrYy
ry RrYy Rryy rrYy rryy
Thus, the possible gnotypes would be
RRYY-1
RRYy-2
RrYY-2
RrYy-4
RRyy- 1
Rryy-2
rrYY-1
rrYy-2
rryy-1
The phenotypic ration for this cross is
. This is a standard cross result between two heterozygous parents.
