Gregor Mendel's research consisted of using parent pea plants that were pure breeds. What genotype(s) would be considered pure breeds? (use the letter "B" and/or "b" in your genotype) *

Answer:

The genotypes thatwould be considered pure breeds are BB and bb

Step-by-step 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.
