In a species of flowers red petals are dominant to orange petals. If two plants heterozygous for red petals are crossed what are the possible genotypes of the offspring

The possible genotypes of the offspring when two plants heterozygous for red petals are crossed is RO × RO   → RR, OR, RO, OO or

1 homozygous for red petals, 2 heterozygous for red petals and 1 homozygous for orange petals.

Explanation:

To solve the question, we note that

The red petals are dominant to the orange petals

Let R = Red and

O = Orange

Therefore we have

RO × RO

That is

                                            R                                O

                               R           RR                               OR

                               O           RO                              OO

RO × RO   → RR, OR, RO, OO

That is possible  genotypes of the offspring when the  heterozygous for red petals are crossed, RO × RO   is  RR, OR, RO, OO

Given one homozygous for red petals, two  heterozygous for red petals and one homozygous for orange petals.

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.
