In rabbits, the allele for black fur color (B) is dominant to the allele for brown fur color (b), and the allele for short fur (F) is dominant to the allele for long fur (f).
If a cross between two rabbits that are heterozygous for both traits results in 16 offspring, how many of the offspring can be expected to have short brown fur?

Active transport
A forest is cut down for farming. What is likely to happen to the biodiversity in that area?
Biodiversity will decrease due to habitat loss and reduced resources
What biomolecule makes up the majority of the cell membrane?
Lipids
What is the function of a vaccine
to expose your immune system to a weakened virus so it learns to fight it
