There are some organelles which are found in plant cells but which are not found in the animal cells, these structures will provide a positive identification of a plant cell under a microscope.
The structures which would provide a positive identification of a plant cell under a microscope are CENTRAL VACUOLE, CHLOROPLAST [PLASTIDS] AND CELL WALL. These structures are only present in plant cells.
The answer is C DNA and that is the answer
Answer:
The genotypes found in the F2 offspring will be An1An1, An1An2 and An2An2.
Explanation:
In the example given in the question, the color of the petals of snapdragon flowers are given with the An1 allele having full activity and the An2 allele being the null allele. For the F1 offspring, two snapdragon flowers are crossed, one with red petals which is An1An1 and one with ivory petals which is An2An2. All the genotypes for the F1 offspring will result in An1An2.
Then using this F1 offspring, the F2 offspring is found and the genotype of the F2 offspring will be An1An1 / An1An2 / An1An2 / An2An2.
So the genotypes found in the F2 offspring will be An1An1, An1An2 and An2An2. One red petal snapdragon, 1 ivory snapdragon and 2 pink snapdragons.
I hope this answer helps.
The nucleus is what houses the cells genetic information. Hope this helps!
