What is the phenotype of a heterozygous dominate purple rat?

a. rr

b. rr

c. rr

d. purple


plzzz hurry 30 points

The answer is actually D. This is because the phenotype is really the trait that is determined by the alleles.

I believe it is B.

Remember that heterozygous refers to having two different alleles of a gene, and that dominant traits are represented by CAPITAL letters.

In this case, B is most likely correct. If not, than it has to be C.

Good luck!

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8
