Answer:
1) They wil be BR (100% of them)
Punnett square:
R. R
B. BR. BR.
B. BR. BR
a) there is a 0% chance
b) there is a 0% chance
c) there is a 100% chance
Explanation:
a) because on the punnet square we got no "BB"
b) because on the punnett square we got no "RR"
c) because on the punnet square all of the crosses resulted in "BR", hence 100%
Answer:
Not passed along or it is recessive
Explanation:
There are two reasons for the shift in tail length in mice. The first reason could be that the tail length of mice is a recessive trait. In a population where there are also dominant traits, these traits may not show but still be in the population via the heterozygous individuals. The second reason that there may be fewer mice with short tails is that this phenotype causes some survival incompatibility that they may not survive to reproductive years or are not chosen by other mice to cross with. The short tail then does not get passes on.

Explanation:
I abreviated the text in each box, but you should get the gist of which belongs in which categories. Let me know if you need further explanation on what warrants classification in the observation, classification, and experimentation categories.
