In guinea pig short hair is dominant to long hair two guinea pigs that are heterozygous for short hair are crossed what is the phenotypic ratio for this cross

1 homogeneous short hair, 2 heterogeneous short hair, 1 homogeneous long hair.

Explanation:

HH = dominant

Hh = dominant recessive

hh = recessive

they float because they are less dense than the water itself

something denser than water, like a rock, will sink to the bottom

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
