What are the mechanisms by which aneuploidy and polyploidy are caused? What are the mechanisms by which aneuploidy and polyploid

y are caused? The principal cause of aneuploidy is chromosome nondisjunction during mitosis or meiosis. Polyploidy in nature can result either from the duplication of euploid chromosome sets from a single species or from the combining of chromosome sets from different species. The principal cause of aneuploidy is paternal chromosome nondisjunction during meiosis. Polyploidy in nature results from the combining of chromosome sets from different species. The principal cause of aneuploidy is chromosome nondisjunction during mitosis. Polyploidy in nature can result from the deletion of one chromosome set during meiosis or during the first mitotic division. The principal cause of aneuploidy is maternal chromosome nondisjunction during meiosis. Polyploidy in nature results from the deletion of one chromosome set in somatic cells.

The correct answer is:

The principal cause of aneuploidy is chromosome nondisjunction during mitosis or meiosis. Polyploidy in nature can result either from the duplication of euploid chromosome sets from a single species or from the combining of chromosome sets from different species.  

Aneuploidy is a phenomenon when there is the presence of an abnormal number of chromosomes in a cell (an extra or missing chromosome). Usually it appears as a result of improper cell division (chromosomes don’t separate) and it can cause many genetic disorders.

Polyploidy refers to a state when there are more than two sets of chromosomes (one from mother one from father). Triploid (three sets of chromosomes) and tetraploid (four sets of chromosomes) chromosomes are examples of polyploidy. This phenomenon is most common in plants.

Answer:

I HOPE IT WILL HELP U

Explanation:

Majority of the people in the poorest regions of the tropics rely on poultry production as their major source of protein supply. However, poultry production is hindered by the harsh environmental conditions in this regions therefore, reducing the daily supply of protein. It is believed that understanding heat stress in birds by paying detail attention to the sources of heat generation in a poultry house can help manage the heat stress situation in this region. This text reviews the internal climatic conditions of the poultry houses, how the birds respond to them, and their implications for heat management in poultry production. Thus, it provides pertinent information for guidance on parameters for open poultry houses architectural design that ensures optimum climatic conditions that will alleviate heat stress problem in poultry production in hot and humid climate.

The atria of the heart merely need to allow blood to flow into the ventricle, and therefore aren't very muscular. 

The ventricles of the heart need to actually pump blood to the rest of the body, whether to the lungs or the the rest of the body.
