When mendel crossed peas with rr and rr genotypes (where r is dominant and produces wrinkled peas and r is recessive and results
LuckyWell [14K]
I think your question all turn into lowercases, uppercases, and lowercases are important in genetics because it can differentiate between the dominant and recessive forms. 
let me explain at least how to calculate the offspring percentage:
for example, you have Rr crossed with another Rr (R for wrinkled peas and r for smooth peas), you just have to match between the four letters, and you will have four possibilities:
R and R
R and r
r and R
r and r
you will have RR, Rr, Rr, and rr
if we convert into percentages, it will give: 
25% RR
50% Rr (there's two Rr so 25 + 25)
25% rr

What would happen to an organism if mitosis did not occur? Check all that apply.
vitfil [10]

The correct options are:

The organism would not grow.

If an organism were cut or burned, the damaged area would not heal.

The organism would not produce new cells.

The mitosis is essential for the division of the cells. The division of the cells allow the organism to grow and heal the damaged cells. The division of the cells replace the old cells and multiply the number of the cells in an organism. hence, in any condition, the organism would be affected and in the absence of the mitosis, the organism cannot heal and cannot grow, due to non-production of new cells.
