The correct answer is a cell.

The basic life building block is the cell.

The cell is termed as the biological, functional and structural unit of every living organisms. They are referred to as building blocks.

Cell biology is the study of cell. Cytoplasm is being found in the cell which is enclosed in a membrane. The biomolecules which are contained in a cell include nucleic acids and proteins.

There are organisms which contains single cell for example, bacteria and those which are multicellular for example, animals and plants.

Flower color in snapdragons results from the amount of the pigment anthocyanin in the petals. Red flowers are produced by plants

USPshnik [31]

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.
