Suppose you have found a new species of plant. Some of the plants have yellow flowers, and some have red flowers. You cross a red-flowering plant with a yellow-flowering plant. All of the offspring have orange flowers. Suggest a possible genotype for the offspring.

Explanation:

1.  Let  red flower as R;

and yellow flower as r;

2. As given, while crossing red plant with yellow plant, all the offspring have orange flower.

So both the parents must be homozygous for their color.

So red is homozygous RR and yellow is homozygous rr.

3. crosse between RR × rr

So  all progeny is heterozygous Rr ( orange flower)

4. It is the example of INCOMPLETE DOMINANCE ,

Heterozygous individuals show a mixed intermediate phenotype ( Rr = orange flowers, not red or yellow).

answer: a) a compound microscope has a greater magnification ability than a simple microscope.
