Answer: A . Has its collagen fibers randomly orientated.
Explanation:
In the microscopic anatomy of the bone, an osteon (basic microscope unit of the bone) can be arranged into two categories; woven bone or lamellar bone.
As the name suggests woven bone is characterized by the random orientation of the collagen fibers . These collagen fibers haphazardly form to give the visual appearance of an intertwined (woven) network of collagen fibers.
Due to the randomness of the collagen fibers orientation woven bone is thus mechanically weaker than lamellar bone. Woven bone is formed/produced when osteoblasts produce osteoids rapidly within the bone matrix thus woven bone has the ability to form quickly as needed.
Woven bone is thus immature bone or pathologic bone with no stress orientation, it has a high percentage of osteocytes per unit volume and a high rate of turnover.
Answer:
The inheritance pattern is CODOMINANCE
Explanation:
Codominance is a type of non-mendelian inheritance i.e. does not follow Mendel's principles of inheritance, in which two alleles of a gene are both dominant, hence, they are both simultaneously expressed in that gene.
Examples or cases of codominance are the AB blood type in humans where alleles A and B are both expressed in the gene. Also, red and white striped flowers in certain plants is an example of codominance as red and white alleles are both expressed.
Answer: Always and always
Explanation:
Within any large animal population there is always a variety of traits seen in the population. When there is a large number of individuals in a population then there are chances that there a genetic diversity.
Sexual reproduction in the organism can lead to the genetic variation in the organism. There are chances to have more variation in the population having more organism.
Two different organism are genetically different and there are variety of traits seen in the two animals that belongs to different species.
Crossing over is termed as a process by which genetic materials are exchanged by non-sister chromatids during meiosis.
Crossing over results in the new combination of information in genetic for, the cell for a specific trait.
It ensures that organisms are identical from one generation to another. Genetic recombination allows variations in genetic materials which are passed through generations.
