They do not produce d.seeds
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.

The work done is 20J
<u>Explanation:</u>
Given:
Force, F = 10N
Distance, x = 2m
Work done, W = ?
We know,
Work = Force X distance
On substituting the value we get:
W = 10 X 2 J
W = 20J
Therefore, the work done is 20J
