During prophase 1 of meiosis, these pairs form a tetrad in a process called

Why aren't the stains like crystal violet and safranin washed away with water during simple staining?

Why was the sample heated in step 5? describe the chemical principles involved in the reasoning behind this step?

In fruit flies, gray bodies (g) are dominant over black bodies (g), and brown pigments (n) are dominant over yellow pigments (n). each individual possesses two alleles for each trait. if a fly that is homozygous dominant for both traits is crossed with a fly that is homozygous recessive for both traits, what is the predicted genotype of the offspring.
