In rabbits, coat color is governed by four alleles: C for dark gray, Cch for chinchilla, Ch for himalayan, and c for
white. This is an example of:
epistasis.
X-linked genes.
•
codominance.
multiple alleles.

Ithink the answer is d.

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature

Ithink its because more have died recently than in the past.
