Answer:
Please find the explanation of the four possible exceptions to Mendelian genetics below.
Explanation:
Genetics, generally, has to do with how genes are inherited or transferred from parents to offsprings. Gregor Mendel, however, explained this concept in his principles of inheritance called Mendelian genetics. There are, however, exceptions to this mendelian principle called Non-mendelian pattern of inheritance i.e patterns of inheritance that do not follow Mendel's principles. Four of them are explained below:
- Incomplete dominance- This non-mendelian inheritance pattern occurs when one allele of a gene does not completely mask its allelic pair, but instead forms an intermediate phenotype. This is in contrast with Mendelian genetics that proposes complete dominance. For example, a red and white flower produce a pink flower (intermediate).
- Codominance- This is another non-mendelian inheritance where two alleles of a gene are simultaneously expressed. For example, roan cattles is a combination of both red and white hairs.
- Multiple alleles: Some traits in a population are controlled by more than two alleles, as explained in mendelian inheritance. Examples of trait controlled by multiple alleles is height in humans.
- Sex-linked inheritance: Some traits are controlled by genes on sex chromosomes i.e. X and Y chromosomes. This genes exhibit inheritance pattern that are different from Mendel's. Example is haemophilia disease controlled by an affected gene on the X-chromosome.
I believe the answer is spores..
Answer:
The first way is when cells grow old or become damaged, they die, and new cells take their place. Sometimes this orderly process breaks down, and abnormal or damaged cells grow and multiply when they shouldn't, when this happens it is usually noncancerous (benign). The second way is when the body’s normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, when this happens more often then not the tumor is usually cancerous.

Answer:
Tetanus Neurotoxin ( TeNT)binds to the presynaptic membrane of the neuromuscular junction is internalized and transported retroaxonally to the spinal cord.The spastic paralysis induced by the toxin is due to the blockade of neurotransmitter release from spinal inhibitory interneurons.
Explanation:
The muscular rigidity and spasms of tetanus are caused by tetanus toxin(tetanospasmin) which is produced by Clostridium tetani, an anaerobic bacillus whose spores survive in soil and cause infection by contaminating wounds.
Tetanus Neurotoxin ( TeNT)binds to the presynaptic membrane of the neuromuscular junction is internalized and transported retroaxonally to the spinal cord.The spastic paralysis induced by the toxin is due to the blockade of neurotransmitter release from spinal inhibitory interneurons.
The tetanus shots is a safe and effective way to prevent tetanus and other dangeroud diseases occuring in most cases.
