Types of procedures that could increase the validity of conclusions from experiements are ...

Single-blind procedures - the subject does not know which treatment they receive

Double Blind procedures - neither the experiementer or the subject know the treatments they receive

matched pairs experiements - used in experimental research in order for different experimental conditions to be observed while being able to control for individual difference by matching similar subjects or groups with each other.

experiments with a control and lots of trials and so fourth!

Purple flowers are dominant to white flowers. A heterozygous purple flower is crossed with a white flower. What are the probabil

Zanzabum

Answer:

50% probability of Pp (purple) or pp (white) genotype.

Explanation:

P = purple gene

p = white gene

Punnet squares show the possible genotypes and probabilities of each genotype in the offspring of a cross:

Purple flower genotype (heterozygous) = Pp

White flower genotype = pp

Punnet Square:

$\left[\begin{array}{ccc}&P&p\\p&Pp&pp\\p&Pp&pp\end{array}\right]$

Potential genotypes for offspring are Pp and pp;

According to the Punnett square, 2 of 4 offspring will have the Pp genotype and the other 2 will have pp genotypes;

This means 2 should be purple and 2 white;

Or, there is a 50% chance of having either genotype, of being purple or white.
