If round pea shape is dominant to wrinkled pea shape, which of the following genotypes would produce the wrinkled phenotype?
A. RR
B. Rr
C. rr

C. rr

Explanation:

The dominant genotype will always be denoted by the capital version, or in this case R.

The round pea shape is dominant to the wrinkled pea shape, which means that, in the Punnett Square, the combinations of RR, Rr, rR, will all come out to be round pea shape.

The last box, rr, would be the one that gives the wrinkled phenotype.

In this case, by ratio, wrinkled phenotype show up 25%

                    by ratio, round phenotype show up 75%.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
