In rabbits, black fur (B) is dominant over brown fur (b). If a rabbit has brown fur, what can you conclude about its genotype?
It is BB.
It is Bb
It is brown
It is bb.
Why are there no white rabbit babies?
The white gene is not present in any of the babies.
It takes two recessive genes to show the trait.
Grey is a better color.
Baby five will be white.

IA IB
ii
What inheritance patterns makes the blood type AB possible?
incomplete dominance
multiple alleles
codominance
total dominance

incomplete dominance
codominance
codependant
cooperative

D) Budding
In an experiment, a student wants to test the effect of different light intensities on the rate of photosynthesis in aquatic plants. Which of the following should be the independent variable?
A) The type of plant used
B) The rate of photosynthesis
C) The light intensity
D) The amount of water
A population of rabbits is studied over several generations. It is observed that the frequency of a particular allele increases in the population. Which of the following is the most likely explanation for this observation?
