Answer:
The genotypes thatwould be considered pure breeds are BB and bb
Explanation:
The genotype of an organism refers to an organism's complete set of genetic material or genes.
Genes are units of DNA that carries information for a particular physical or functional trait or character in an organism. Some genes act as instructions to make proteins while some genes do not code for proteins. The proteins made by a gene expresses the traits and characters of that organisms. Genes for a particular trait may have one or more variants known as alleles.
In Gregor Mendel's research using pea plants, flower colour in a pea plant had two different alleles; one for red flower colour and one for white flower colour. If a plant had the same allele for flower colour, the plant was considered a pure breed.
For example, given B was the allele for red flower colour and b was the allele for white flower colour, a plant having the two alleles for white flower colour bb, is a pure breed. Similarly, a plant having the two alleles for red flower colour, BB is a true breed.

These organelles group together to eventually form cells, or the basic units of all living things.
Organelles are specialized structures in the cytoplasm of cells which provide essential cell functions and are composed of different molecules (macromolecules). Cells as the smallest basic units of life are then grouped in tissues (similar cells which provide a specific function), layers of different tissues work together to provide specific function and form organ, organ group in organ systems which then compose the whole organism.
