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.

h let me think

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
