Black fur is dominant to white fur in guinea pigs. if two guinea pigs (bb) are crossed what color and in what percentage what is the probability of the cross resulting in black fur?

I believe that the odds are strong that the off-spring would be 1/4 black, 1/2 black and white, and 1/4 white:

Bb x Bb = ¼ BB (all black); ½ Bb (black and white ) ;¼ bb (all white).

good one: produce hormones that plants grow.

bad one: the problem with organic matter is that while plant nutrients are needed for crop growth, they can also stimulate excessive growth of the wrong plants – mainly, algae.

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less

hope i even just a little : )
