<span>First determining if the cells in the tumor have common and the unique genetic and biochemical marker and if they are present, that would clearly mean that they all were created from a initially mutated cell and formed the marker and these are considered as monoclonal. If that is not the case and cells do not have a common origin, these are called as polyclonal.</span>
The purpose for which a pedigree chart might be prepared is to identify the pattern of inheritance of a particular trait.
This pedigree chart is created so as to see which traits this new offspring has inherited from its ancestors and which may possibly be transferred onto a new offspring later on in its life. It is formed in order to find patterns of inheritance and see what the most important traits that get inherited are.
Answer:
Explanation:
f(a) = freq of recessive allele
f(A) = freq dominant allele
f(a)^2 = (140/500) = 0,28 -> f(a) =
= 0,53
f(A) = 1 - f(a) = 0,47
f(aa) = f(a)^2 = 0,28
f(AA) = f(A)^2 = 0,22
f(Aa) = 1- 0,28 - 0,22 = 0,50
Answer:
A plant cell.
Explanation:
Plant cells are part of multicellular organisms. They form tissues and are differentiated. If we see a section of plant cells, we can see that they have a box-like shape. <u>This happens because plant cells, besides the membrane, are surrounded by a </u><u>cell wall</u><u>, which is rigid and gives the cell this form</u>.
They also do photosynthesis, which is a metabolic process where they obtain energy from the radiation of the sun. To capture the photons they have pigments, especially a green pigment called chlorophyll. <u>The chlorophyll is not free in the cytoplasm, it is contained in a bean-shaped organelle called chloroplast, and therefore they give the </u><u>chloroplast this distinctive green color. </u>
