When neither gene in a genotype pair is dominant and neither gene is recessive, the genes are said to be

c.more precipitation,but only when emission levels.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave
