Answer:
While penetrance is a quantitative estimate, reduced expressivity (transmission) is a qualitative estimate.
Explanation:
<u>Penetration
</u>
Some individuals who carry the deleterious allele (for example, in an autosomal dominant disease) do not show the expected phenotype: in that case we say that the penetrance is incomplete. This is the case in which the number of individuals presenting an abnormal phenotype is less than the number of individuals carrying the mutation causing this phenotype. Penetrance is a quantitative estimate.
For example, in the case of neurofibromatosis type I, its penetration is estimated to be 80% although it is often difficult to detect mild variants of the disease. Therefore, in these cases it would be useful to be able to detect the different mutations in the affected families and thus establish more precisely the value of their penetrance.
<u>Expressiveness (transmission)</u>
The observed phenotype can be more or less severe among the different affected individuals. In this case it is said that the deleterious allele has a variable expressiveness. Expressiveness is a qualitative estimate.
In the case of Marfan syndrome, for the same mutation present in a family, some individuals show a severe form of the disease that affects the cardiovascular, ocular and skeletal system while others show only a high height and arachnodactyly, without eye problems or of aortic aneurysm.
Reduced penetrance and incomplete expressivity are mainly described in autosomal dominant diseases.
Do not confuse an isolated case due to poor penetrance with a sporadic case due to the appearance of a mutation.
Endoplasm<span> generally refers to the inner (often granulated), dense part of a cell's cytoplasm. This is opposed to the </span>ectoplasm<span> which is the outer (non-granulated) layer of the cytoplasm, which is typically watery and immediately adjacent to the plasma membrane.</span>
If the Na+ voltage-gated channels in a muscle cell open, the Na (sodium) ions rush inside the muscle cell and makes the cell more positive as Na ions carry positive charge on it. Due to the entry of positively charged ions inside the cell, the cell becomes less negative and more positive. This is called depolarization of cell.
Answer:
It will be full black bc the full color has dominat agents all the other rabbits
Explanation:
The sum total of the interactions of the variety of organisms in the biosphere is called biodiversity.
The term "biodiversity" describes the wide range of organisms that are alive today, including flora, fauna, bacteria, and fungi.
The vast variety of life on Earth is referred to as biodiversity. It can be applied more precisely to all the species found in a given area or ecosystem. Every living creature, which include plants, microbes, animals, and people, is referred to as biodiversity. Around 8.7 million species of plants and animals are thought to exist, according to scientists. However, to date, only about 1.2 million species, the majority of which are insects, have been recognised and described. This means that the identities of millions of other organisms are still unknown.
